摘要： Proposed is a hydrostatic radial-piston motor (10) with an adjustable cylinder ring (18) which has integrated means designed to determine the eccentricity (20) between the cylinder ring (18) and the rotor (14). The eccentric position of the cylinder ring (18) leads, in conjunction with the rotating rotor (14) and the restraining of the guide shoes (17) on the cylinder ring (18), to a stroke action of the piston (16) in the radial direction. This, and kinematic conditions in the motor (10), leads to a change in the distance between two consecutive guide shoes (17). This change in distance takes place in proportion to the eccentricity (20) of the cylinder ring (18) and is determined by a measuring device. This measuring device has a signal transducer (27) which generates an amplified voltage signal as the guide shoes, which act as signal generators, move over it. This signal is fed to evaluation electronics (28) where it is used to determine the eccentricity, rotor rpm and other parameters.

摘要： An angle adjustment mechanism for a pump and a motor includes a base, an eccentric bushing and a fixed link. The base has a motor flange for mounting a motor, a pump flange opposite the motor flange for mounting a pump, a hinge disposed between the motor flange and the pump flange and a pair of spaced apertures disposed opposite the hinge. The eccentric bushing has a body portion received in one of the apertures of the base and an inner bore with an axial center line offset from an axial center line of the body portion. The fixed link has a first pin portion received in the inner bore of the eccentric bushing and a second pin portion received in the other of the apertures of the base. With this arrangement, rotation of the eccentric bushing changes the distance between the apertures of the base, thereby changing an angle between the motor flange and the pump flange about the hinge.

摘要： A rotary pump consists of a cam ring, a rotor disposed within the cam ring, and a pump body enclosing the cam ring and the rotor. The cam ring includes a cam surface having a centre of symmetry. The rotor has a centre of rotation which coincides with the centre of symmetry of the cam surface, and includes a plurality of fluid chambers. Each fluid chamber comprises an aperture opening into a circumference of the rotor, and a pump element sealingly disposed within the aperture. As the rotor revolves, each element remains in contact with the cam surface and moves over a stroke length between a first position adjacent the radial innermost portion of the respective aperture and a second position adjacent the radial outermost portion of the respective aperture. The pump body includes a fluid inlet and a fluid outlet respectively for transferring fluid to and fluid from the fluid chambers as the rotor rotates. Preferably, the pump also includes an actuator for rotating the cam ring about its centre of symmetry between a first angular position and a second angular position for varying the stroke length of the pump elements.

摘要： The invention concerns an adjustable hydrostatic pump (10), in particular a reciprocating pump, whose lifting ring (22) can be adjusted by means of a hydromechanical adjustment device (35) and which comprises an active noise-attenuation arrangement. The pressure chamber (39) of an adjusting piston (37), which acts on the lifting ring (22), is acted on by an additional control device (47), parallel to the hydromechanical pressure regulator (41), with pressure variations such that the oscillating effects of mechanical forces on the hydraulic clamping of the lifting ring (22) are reduced, so decreasing the development of noise of the reciprocating pump.
