    摘要: A bent axis type variable displacement hydraulic machine employing hydrostatic radial bearings for supporting hydraulic reaction forces exerted on the cylinder block. In a hydraulic machine of this sort, the number of pistons which are located in the high pressure are varies with the rotation of the cylinder block, and the resultant force of hydraulic reaction forces has an acting point at a position off the axis of the rotational shaft. Therefore, the hydrostatic radial bearings are located in such positions as to balance the moment loads which occur about the rotational shaft in relation with the acting point of the resultant force of radial hydraulic reaction forces on the drive disc of the rotational shaft. As a result, it becomes possible to lead to suppression of oil leaks from the sliding surfaces to a minimal rate and to prevent abnormal abrasive wear of each of the sliding surfaces.

    摘要: A variable displacement hydrostatic axial piston machine has a cylinder barrel which is rotatable in a yoke and has a plurality of circumferentially spaced cylinder bores in which are mounted pistons which with the ends of their associated piston rods are journalled in a drive disk on a machine shaft rotatably mounted in the casing of the machine. The yoke is mounted in said casing pivotable about a transfer axis through the drive disk center by means of an adjustment device for varying the displacement and possibly also the mode of the operation of the machine, in the yoke and the machine casing furthermore being disposed a pair of hydraulic fluid connecting conduits. For obtaining a lighter and more compact design of the machine the yoke is formed with a guiding segment instead of another leg, said segment being adapted to be moved in a curved guide path in the casing located in a plane perpendicular to the pivot axis of the yoke, one of the connecting conduits for hydraulic fluid to the cylinder barrel extending within said yoke leg while the other is formed by a hollow space in the machine casing, and the adjustment device comprises two cylinder bores in the yoke with adjustment pistons therein and an adjustment valve for selectively connecting one of said pair of adjustment cylinder bores with one of the hydraulic fluid conduits for adjusting the yoke.

    摘要: A hydrostatic machine, in particular of bent axis design comprises a clutch which is provided between the drive shaft and the pistons. The force necessary for clutch engagement is produced by hydraulic pressure forces which are either applied to the pistons or delivered by the pistons depending on whether the machine operates as a motor or as a pump. When the machine neither produces a moment nor receives a moment the clutch is automatically disengaged due to the reduction of the hydraulic pressure forces. According to the invention the clutch helps to prevent hydraulic losses of the machine while running idle and improves the overall efficiency.

    摘要: A multicylinder hydraulic machine of the split-shaft kind comprises a rotatable shaft and a drive plate fixed on the shaft and linked to piston and rod units received in the cylinders of the drum. Liquid flow is through orifices in a distribution plate non-rotatably positioned around the shaft, through ducts in the drive plate and through the piston and rod units which are hollow. The shaft is rotatably mounted and axially located by conical bearings. The distribution plate is mounted in an axially floating manner and a hydraulic abutment is developed between the distribution plate and the drive plate during operation of the machine so as to reduce the force on the shaft bearings.

    摘要: An axial piston pump arrangement in which pistons are guided in cylinders provided in a cylinder block. The latter has channels for releasing liquid pressure within the cylinders in an area between kidney-shaped control openings that are arranged in the distributor plate. The channels are arranged in the cylinder block and feed into the cylinders at a location on the cylinder walls, which is uncovered by the pistons when the swash plate actuating the pistons, is at a substantially large inclination. These channels lead from the outside of the cylinder block to the internal walls of the cylinders, and are arranged radially in the cylinder block in the form of bores. At least two of the channels are arranged at various distances from the distributor plate in the area of the cylinder walls, so that an increasing number of channels is uncovered with increased inclination of the swash plate. The channels may have increasing diameter at increasing distance from the distributor plate.

    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.
