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