Abstract (en)
[origin: WO2019113036A1] An angle adjustment mechanism for a pump and a motor includes a base, two eccentric bushings and a fixed link. The base has a hinge disposed between a motor flange and a pump flange and a pair of spaced apertures disposed opposite the hinge. The first eccentric bushing has a body portion received in a first of the apertures of the base and the second eccentric bushing has a body portion received in one of a second of the apertures of the base or an inner bore of the first eccentric bushing. The axial center line of the inner bore of the first eccentric bushing is offset from an axial center line of the body portion by a first distance and the axial center line of the inner bore of the second eccentric bushing is offset from an axial center line of the body portion by a second distance, wherein the second distance is different from the first distance.
