    摘要： An axial piston machine includes a housing, a drive shaft, and a cylinder drum. The drive shaft is mounted in the housing so as to be rotatable with respect to a first axis of rotation. The cylinder drum is mounted so as to be rotatable with respect to a second axis of rotation. The cylinder drum has at least one cylinder bore that linearly guides an elongate piston. The piston has a first end connected to the drive shaft by a ball joint and a section in the form of a circular cone which tapers toward the first end. The piston also has a spherical section at the second end that is situated opposite the first end. The cone-shaped section merges without offsets and kinks into the spherical section. The piston has a flat end face at the second end which defines a plane that intersects the spherical section.

    摘要： In a bent axis hydraulic machine, a back plate and cylinder barrel vary in distance from a drive plate as a stroke angle of the cylinder barrel changes, thereby minimizing unswept fluid volume in the cylinders of the barrel at any stroke angle. Distance is controlled by one or more rollers, engaging respective tracks that define a profile of contact that determines the distance as a function of the stroke angle. Telescoping fluid supply channels are employed to maintain a fluid supply to the cylinder barrel as the distance changes.

    摘要： A floating cup pump assembly incorporating a tilted swashplate structure with cup elements projecting away from either side of the swashplate structure. The swashplate structure is positioned between a first group of matedly engaged piston elements and a second group of matedly engaged piston elements. The piston elements rotate around a first axis and the cup elements rotate around a different axis causing the cups to reciprocate relative to the piston elements.

    摘要： A hydrostatic module is disclosed, including a pair of shafts rotatably supported by a frame. Two yokes are pivotally mounted on the frame, each having complimentary surfaces to the other yoke and to the frame, minimizing the space occupied by the yokes. Stop means are provided on the yokes and on the frame to limit the pivotal movement of the yokes. A hydrostatic power unit is carried by each yoke, each connected to one of the shafts. A control system, having a single piece control housing containing servo pistons, pivots the yokes. The servo pistons independently determine the orientation of the yokes. A single piece fluid control porting plate is secured to the control housing to route hydraulic fluid to multiple locations within the control housing. A fluid manifold serves as a main structural element, with intimate proximity between the manifold and the control housing allowing simplified fluid exchange therebetween.

    摘要： Sufficient pressure is produced in a pocket of a hydrostatic bearing when a corresponding cylinder is about to switch from a suction stroke to a discharge stroke in order to prevent solid contact of sliding faces. A plurality of cylinders are arranged on a circle around a center axis of a cylinder block rotatably supported in a housing. Pistons reciprocates in the respective cylinders. A suction port and a discharge port provided to the housing selectively communicate with the respective cylinders in accordance with a rotational position of the cylinder block. A drive shaft inclined relative to the center axis of the cylinder block, a rotation transmitting mechanism for transmitting rotation of the drive shaft to the cylinder block for rotating the cylinder block synchronously with the drive shaft, and a rotating disk rotating together with the drive shaft and cooperatively engaged with the pistons are further provided. A fixed sliding contact face is formed in the housing to have a sliding contact with a rear face of the rotating disk. Pressure pockets are formed on the rear face of the rotating disk in correspondence with positions of the respective pistons. Pressure paths for conducting hydraulic pressure in the respective cylinders to the respective pressure pockets via the pistons are further provided. There is further provided a pressure introducing mechanism for introducing a high pressure fluid to a pocket moving along the fixed sliding contact face along with the rotating disk at a position in which a corresponding cylinder is about to switch from a suction stroke to a discharge stroke.
