摘要： An axial piston machine of the swashplate type has a movable valve plate at the piston end of the cylinder block, and displacement of the valve plate by a stroke control mechanism changes the tilt of the block. The valve plate has a front face subjected to the hydraulic end thrust of the cylinder block and a back face shaped conformably to and engaged with a cylindrical slideway in the machine body. The valve plate is guided against displacement in the direction of the axis of tilt by side surfaces of the machine body. At least one of the front and back faces is spherically arched to cause the hydraulic end thrust to urge the valve plate in a direction to keep one of its sides in continuous contact with a cooperating side face in the machine body. This prevents jamming and wedging of the valve plate in the slideway when the tilt of the cylinder block is adjusted, regardless of the existing load.

摘要： The invention relates to a method of producing concave, self-contained bearing surfaces, which are at least part of spherical indentations which extend beyond the sphere equator, by means of machining involving the removal of material of pre-formed indentations in workpieces by means of a tool having a tool cutting edge orbiting around a tool axis of rotation with an orbit diameter which is equal to the length of a chord extending up to a deepest point of the bearing surface, whereby the cutting movement is made up of the orbital movement of the tool cutting edge and a rotational relative movement between workpiece and tool around a vertical axis through the sphere center, and the feed movement is a movement of the tool relative to the workpiece along the tool axis of rotation which is obliquely set at the same angle of inclination relative to the vertical axis as is the chord set to the sphere equator. For reducing manufacturing times and increasing the dimensional exactitude of the bearing surface it is proposed in accordance with the invention that the chord (S) originates from the sphere equator (A), and the regions of the indentation (7) to the two sides of the sphere equator (A) are machined with two separate feed movements. The invention further relates to a bearing surface as product of this method.

摘要： An axial piston machine whose pistons are formed as stepped pistons and which bound a first cylinder space and a second cylinder space, wherein the pistons are driven on the driving side via an axially displaceable driving surface on which they slide in a sliding bearing with a pressure pocket which is connected to the first cylinder space by a passage, is arranged so that the loading of the sliding bearings is reduced depending on the operating condition of the axial piston machine. This is achieved by connecting the second cylinder space to a second pressure pocket on one of the two sliding surfaces by a second passage separate from the first passage.

摘要： The invention relates to a pressure averager for providing an averaged working pressure from the operating pressures of at least two sources of pressure medium, there being provided to average the operating pressures a differential piston of which the number of step faces which face the same direction and which are of equal size corresponds to the number of operating pressures to be averaged, of which the oppositely directed working face is equal to the sum of the step faces, and which is displaceably guided in a correspondingly stepped housing which is provided with supply lines for the operating pressures, and its object is to develop the pressure averager in such a way that an additional pressure relief valve is not required for its function within a hydraulic installation. This is achieved in that annular grooves in each case associated with a control edge of the respective step faces are provided in the housing, and in that leading away from the annular grooves there are discharge lines which are connected to a common line for the averaged pressure which is connected in turn to the working face.

摘要： An axial piston machine has a central bore connected via a connecting duct with the pressure carrying duct of a mirror member. The central bore together with the central pivot acts as a pressure cylinder which exerts a central bearing pressure on the cylinder drum and the mirror member and acts against lifting forces which threaten to lift the mirror member off its slideway. With this additional force it is possible to enlarge the orifices or slots on the rear side of the mirror member so that the area of tilt of the cylinder drum with the mirror member is enlarged. The additional central bearing force applied by the present invention is supported on the drive flange via the central pivot and urges the mirror member against the slideway so as to ensure at all times a secure engagement of the mirror member even when the pressure sides change, that is, a changing direction of tilt of the cylinder drum in a reversing pump.

摘要： The invention relates to a control and regulating device for a hydrostatic transmission which comprises a reversible hydraulic pump that can be driven by a driving motor, at least one hydraulic motor that is connected via two working lines to the hydraulic pump, and an adjusting device that can be acted on by an adjusting pressure for adjusting the volume and direction of displacement of the hydraulic pump, together with a displacement-direction control valve for controlling and regulating the action of the adjusting pressure on the adjusting device, can be actuated as desired both by a control signal that is proportional to the speed of rotation of the driving motor and predetermines the direction of displacement of the hydraulic pump and by a working pressure signal that is proportional to the working pressure in the working line then carrying the high pressure. To enable a load that has been decelerated to a standstill both to be maintained at a standstill and also to be shunted without mechanical braking, even when actuation of the displacement-direction control valve by the control signal is interrupted, the invention provides for switching over the working pressure signal applied to the displacement-direction control valve in the absence of the control signal.

摘要： The invention relates to a braking valve arrangement for a hydrostatic drive operated in open circuit, in particular for vehicle drives, wherein a hydraulic pressure medium is supplied to the hydraulic motor from the hydraulic pump via a reversing directional control valve as desired through one of two branches each containing a pressure limiting valve and a braking control valve, and the pressure medium is discharged to the tank through the respective other of the two branches. The braking control valve controls the flow of hydraulic medium through the respective branch depending on the pressure in the respective other branch and has parallel with it a non-return valve opening into the hydraulic motor. To reduce the outlay in the valve and lines a valve unit is provided in each branch of which the valve body is formed as a closure body of the non-return valve, urged in the closing direction by a spring, as a control piston of the braking control valve and as the housing for the closure element of the pressure limiting valve, wherein the valve body is urged controllably towards the closure position depending on the pressure in the respective other branch, and thus acts as a control piston in cooperation with a valve seat to effect controlled throttling of the flow of pressure medium from the control chamber to the tank.

摘要： The invention is concerned with an axial piston machine, preferably an axial piston pump of the inclined disc or skew axis type, with a cylinder (9) which rotates about an axis of rotation and in which, on a pitch circle, several pistons (8) are movably guided in piston bores (11) extending substantially along the axis of rotation (3), by means of an inclined or driving disc, or the like, the piston bores (11) opening at the face of the cylinder (9) which is remote from the inclined or driving disc (5), the face resting against a control surface (13) in which there are arranged control openings (14), positioned on the pitch circle of the pistons (8) which, in set positions of rotation of the cylinder (9) are covered by the openings of the piston bores (11), loading cylinders (24) being distributed over the circumference and acting upon the cylinder (9) against the control surface (13), and of which loading cylinders the working spaces are connected, by means of connecting channels (27), each with a respective piston bore (11) and the cylinder (9) being supported radially, directly or indirectly, on a support (18) which is fixed relative to the housing (2) and which is spaced axially from the control surface. It is the purpose of the invention, to so arrange the axial piston machine that a balanced axial and radial guidance of the cylinder (9) is possible with maximum use of the piston performance. For achieving this it is arranged that the piston bores (11) open, without narrowing of cross section, at said face (23); that said face (23) is spherically concave and the control surface (13) is correspondingly spherically convex; that the axial portion (F.sub.SK) of a control surface force (F.sub.S), which acts upon the cylinder (9) in the direction of the inclined or driving disc, or counterbalances a loading force (F.sub.ER) which acts upon the cylinder in the opposite direction; and that the size of the radius (R) of the control surface (13) is such that the intersecting point (s) of the control surface force (F.sub.S) perpendicular to the control surface (13) and of the loading force (F.sub.ER) lies in a plane (A) which extends transversely to the axis of rotation (3) and which is arranged in the region of the support (18) of the cylinder (9).
