Abstract:
An adjustable stop assembly for limiting a maximum yoke angle of a hydraulic pump having a fluid displacement proportional to the angle of the yoke, said adjustable stop assembly including a control piston for inclining the yoke to define a desired yoke angle; a stop member defining a set of internal threads and being disposed within a cavity defined by said adjustment assembly, an adjustment screw disposed for rotational motion, comprising means operable to retain said adjustment screw reciprocally stationary relative to said adjustment assembly, said adjustment screw further comprising a first set of external threads for engagement with said internal threads of said stop member, whereby rotation of said adjustment screw causes axial travel of said stop member, thereby displacing said control piston, characterized by:(a) said cavity defining a generally cylindrical internal surface, and further defining a first axis about which said internal surface is concentric; and (b) said set of internal threads defined by said stop member defining a second axis, and said first and second axes being transversely offset.
