摘要： The invention relates to an axial piston machine of the swashplate type in which the drive shaft passes through the swash plate, the swash plate can be tilted about an effective tilt axis so that its working surface supporting the pistons has a radial component of motion relative to the drive shaft as it is tilted in the direction of which the effective tilt axis is displaced parallel as the swashplate is tilted. In order to adjust the swashplate to a larger tilt angle, according to the invention the effective tilt axis is adjusted radially in a direction opposite to the direction of the radial component of motion (R) of the swashplate working surface.

摘要： In a piston for piston machines comprising a hollow body, open at least at its free end, having an axial cavity in which there is a filler piece at least partly filling the latter and consisting of a material of lower specific gravity than the material of the piston, said filler piece being secured in the cavity and being held axially in the cavity by a locking element arranged at the free end of the hollow body and a spring arranged between the locking element and the filler piece, the filler piece is inserted axially and the axial securing and locking is effected solely by the spring, which is pretensioned by the locking element to such an extent that it acts against the filler piece with a spring force greater than the maximum inertial forces of the filler piece acting against the spring to be expected when in operation.

摘要： A control device for a hydrostatic drive for at least two actuators having a variable displacement pump whose adjusting device can be acted on as a function of the displacement and/or of the delivery pressure, wherein a control valve is associated with each actuator in its hydraulic supply line and the delivery flow for each actuator is determined by means of a pressure compensator as a function of the valve preset at the control valve, is simplified while ensuring accurate control. This is achieved by having the adjusting device always set the pump at a displacement which is slightly less than the sum of the actual instantaneous volume flows required by the actuators.

摘要： An axial piston machine of the skew axis type with at least two independent working streams is described. In this at least two groups of working pistons are arranged in cylinder bores, each on a circle, whereby each group of working pistons delivers an independent working stream or provides a working stream with medium. Such an axial piston machine is constructed as a machine in which the delivery volume is continuously adjustable, and in which the angle of inclination of the cylinder drum can be changed by means of an adjusting mechanism. The entrainment of the cylinder drum only takes place through one of the groups of working pistons.

摘要： In a rotary machine a piston member articulated to a rotary drive member reciprocates in a piston-reciprocation chamber in a piston block mounted for rotation obliquely to the drive member. The piston member comprises a first length, whose cross-section decreases with increasing distance in opposite directions from a plane of maximum cross-section corresponding to the chamber cross-section, and an adjacent length, whose cross-section decreases with increasing distance from the first length, engaging in the chamber for torque transmission between the drive member and the block via the piston member.
