摘要： The invention relates to a piston engine comprising a rotatably mounted cylindrical drum (2) provided with a plurality of cylindrical boreholes distributed over the circumference thereof and containing displaceable pistons. Said cylindrical boreholes (3,4) comprise cylindrical openings (35.1, 35.2, . . . 35.9) on one side, which are temporarily connected to one of two control nodules (9, 10) according to the angle of rotation of the cylindrical drum (2), said control nodes being respectively connected to a working line (27, 28). A reversing region (30, 31) is respectively embodied between the control nodules (9, 10), a first end (32) of a pressure compensation line (33) ending in one of the reversing regions (30, 31). A second end (34) of said pressure compensation line (33) ends in the output-side working line (27), the length (L) of the output-side working line (27) between the output-side control nodules (9) and the second end (34) of the pressure compensation line (33) being measured in such a way that a defined phrase relation counteracting the pressure variation exits between a pressure wave caused by a reciprocating motion of the piston (5, 6) and continuing in the output-side working line (27), and the angle of rotation of the cylindrical drum (2).

摘要： A hydrostatic power train includes a hydraulic pump, which is connected, via a first main pipe and a second main pipe, to a first hydromotor unit driving a front axle and to a second hydromotor unit driving a rear axle. The first and second hydromotor units can be adjusted in terms of their displacement via a first and second variation device. A direction of travel is defined as forward movement (F) or reverse movement (R) by a position of an operating lever. The first and the second variation devices are controlled by a control valve which takes up a first control position upon a forward movement (F) determined by the position of the operating ever and which takes up a second control position upon reverse movement (R) determined by the position of the operating lever and which takes up a second control position upon reverse movement (R) determined by the operating lever. In the first control position, the first variation device is controlled such that the first motor unit is adjusted for a smaller displacement and, in the second control position; the second variation device is controlled such that the second motor unit is adjusted for a smaller displacement.

摘要： The gear pump unit (100) comprises a pump cover (1), an internal rotor (16) mounted rotatably in a recess (9) of the pump cover (1) and formed in a rotationally fixed manner on a driven plug-in shaft (11), and an external rotor (19), which is rotatably mounted in the recess (9) of the pump cover (1) eccentrically relative to the axis of rotation (A) of the internal rotor (16). The external rotor (19) is in mesh with the internal rotor (16) only in a first angle-of-rotation range (α). In a second angle-of-rotation range (β) lying opposite the first angle-of-rotation range (α), the internal rotor (16) is in contact with an inner surface (25) of a web (23), which is disposed in the recess (9). The outer surface (26) is in contact with the external rotor (19). After closing of the recess (9) by a cover plate (27) fastened to the pump cover (1), an admission pressure chamber (21) and a low-pressure chamber (22) are therefore formed in the recess (9). A holding element (33), which is held in the pump cover (1), in the initial assembled state of the gear pump unit (100) holds the cover plate (27) at a fixed angle of rotation on the pump cover (1).

摘要： A hydrostatic machine with a cylinder block (6), within which sleeve holes (28b) are arranged, in which sleeves (28) sit, surrounding piston bores (28a) in which pistons (29) are mounted, such as to be displaced back and forth and the pistons (29) extend into the cylinder block (5) such as to define cylinders (26) with the front ends thereof. According to the invention, the risk of piston seizure can be reduced, whereby the sleeves (28) comprise an axially-defined recess (41) in the outer surface thereof, in the region facing away from the cylinder and the region with the greatest piston radial force, pressing the pistons (29) against the wall of the piston bore.
