摘要： The invention relates to a hydrostatic piston engine. The hydrostatic piston engine comprises a housing in which a cylinder drum is arranged in a rotatable manner. In the cylinder drum a first group of cylindrical bores and a second group of cylindrical bores are provided. Each cylindrical bore accommodates a piston that can move in a longitudinal direction and is supported on a swash plate, which is inclinable around at least one pivoting axis. The first group of cylinder bores is connected temporarily by means of first control slits (50, 51) of a control plate with a first hydraulic circulation during a rotation of the cylinder drum. Correspondingly the cylinder bores of the second group are connected temporarily via second control slits (57, 58) of the control plate (32') for a second hydraulic circulation during a rotation of the cylinder drum. The relative position of the first and/or of the second control slits (50, 51; 57, 58) relative to the minimum of one pivoting axis of the swash plate is adjustable.

摘要： The invention relates to a method for the production of a ball jointed connection between a guide shoe (10) and a cylinder piston (1) of a piston machine. A spherical cap-shaped recess (2) is first of all formed on the cylinder piston (1) and/or the guide shoe (10), whereby the recess (2) is undercut in such a way that the spherical cap-shaped recess (2) comprises a solid angle area (α) of over 180°, and the diameter (D) in the region of the equator plane (5) is greater than the diameter (d) of the recess (2). Furthermore, a spherical head (11) is formed on the corresponding counterpart, that is the guide shoe (10) and/or the cylinder piston (1). In accordance with a first version of the invention, the spherical head (11) is pushed into the spherical cap-shaped recess (2) in such a way that the edge area (6) surrounding the spherical cap-shaped recess (2) is elastically deformed when the spherical head (11) is pushed in, and the surrounding edge area (6) grips behind the spherical head (11). Alternatively, the spherical head (11) has a flattening (20) which is plastically deformed after introduction of the spherical head (11) into the recess (2).

摘要： The invention concerns an axial piston machine (1) which comprises a cylinder block (2) having cylinder bores (3, 4) in which pistons (5, 6) are movably guided, said pistons (5, 6) being supported on an inclined or wobble plate (25) in order to perform a lifting movement. The axial piston machine (1) further comprises a pivot device (31) for varying the inclination of the inclined or wobble plate (25) by pivoting about a pivot axis (27). The development according to the invention is provided with a damping element (41) which comprises a damping piston (40) which acts on the inclined or wobble plate (25) and is movably disposed in a damping cylinder (42) which is connected to a pressure fluid reservoir (48) via a throttle element (47) and a non-return valve (44) disposed parallel thereto. The non-return valve (44) enables pressure fluid to flow in an unthrottled manner from the pressure fluid reservoir (48) into the damping cylinder (42) and prevents the pressure fluid from flowing out of the damping cylinder (42) in an unthrottled manner by bypassing the throttle element (47). In this way, a damped pivot movement of the inclined or wobble plate (25) is brought about.

摘要： The invention relates to an axial piston engine (1) comprising a housing (2) and a cylinder drum (5) that is pivotably arranged in one interior space (3) of the housing. Several cylinder bores (6) are embodied in said cylinder drum (5). Pistons (7) are moveably guided in said cylinder bores (6) and rest on a swash plate (11) by means of guide shoes (8). The axial piston engine (1) also comprises a retracting device (15). The guide shoes (8) rest on the retracting device (15) when the pistons (7) are retracted. A restraint system (16) is accommodated in the housing (2), can be moved against a spring (40) and is used for supporting the retracting device (15) at the housing (2). The aim of the invention is to improve and stabilise the support of the retracting device (15). To this end, the retracting device (15) is supported by a support device (16a) which is situated behind the retracting device (15) at the side facing away from the swash plate (11). The support device is connected to the swash plate (11). The restraint system (16) supports the back of an essentially radial locating face (11a) at the swash plate (11) or an add-on piece thereof when the restraint system (16) is pushed into the interior space (3) of the housing.

摘要： The invention relates to an axial piston machine of skew plate construction, the pistons (7, 8) of which are supported on a sliding surface (11) acting as a skew plate of a cradle (12) pivotable about an axis (33). The pivoting angle of the cradle (12) can be adjusted by means of an adjusting device coupled to the cradle (12) via a connecting device (20). According to the invention, the connecting device (20) permits both coupling to a transverse adjuster (30) exerting a translation movement and to a rotating adjuster exerting a rotary movement. To this end, the connecting device (20) has a block (34) located eccentrically in relati on to the axis (33) which works together with a sliding element (32) for the transmission of the translation movement and with an eccentric component secured to a rotary shaft (50) for the transmission of the rotary movement.

摘要： An axial piston machine comprises a housing (1) which receives an eccentric disc (3) and a rotatably mounted cylinder drum (6) having cylinders (26, 28) and pistons (29) which can move to and fro in the former and the ends of which which protrude out of the cylinders (26, 28) are supported on the eccentric disc (3) via a sliding face (31) of a sliding disc (32), and also comprises a hold-down (36), by which the sliding face (31) is held in contact with the sliding disc (32). A pressure which prevails in a pressure space (40) under the sliding shoes (31) compensates partially for a pressure which is exerted on the sliding shoe (32) by the hold-down (36), via a connecting restrictor (43).

摘要： The invention relates to an axial piston engine (1), comprising a housing (2) in whose inner compartment (4) a cylinder drum (17) and a swash plate (26) located axially adjacent thereto are situated. Several piston bores (21) which extend approximately parallel to the central axis of the cylinder drum (17) are located in the same, pistons (23) being displaceably guided in said piston bores. The ends of said pistons facing towards the swash plate (26) are supported on said swash plate (26). A driving shaft (7) is rotatably mounted in the housing (2) and is connected to an engine part in a rotationally fixed manner by a multitooth coupling (19) comprising teeth (43a, 44a) and tooth spaces (43b, 44b) which alternate regularly in a peripheral direction and which engage with each other. At least one feedthrough channel (45) which extends essentially parallel to the axis of rotation of the drive shaft (7) and from one side of the multitooth coupling (19) to the other is located in the area of said multitooth coupling (19). The aim of the invention is to obtain a flow feedthrough and/or a mechanical feedthrough from one side of the multitooth coupling to the other while ensuring that the multitooth coupling is stable and simple to produce. To this end the feedthrough channel (45) is located between at least one tooth crown surface (43d) and a tooth space bottom (44d) located opposite.
