ABSTRACT:
A hydraulic pump is disclosed having an adjusting member for varying yoke angle. The present adjusting member includes a control piston for displacing the yoke so as to define a desired yoke angle. A stop member is provided having threads and retained within the control piston. An adjusting screw for rotational motion is provided and includes an O-ring and a back up ring for sealing between the screw and the pump housing. The screw also includes a threaded portion for engaging the threads of the stop member. Rotation of the screw advances the threads while remaining stationary, displacing the control piston to limit the maximum inclination of the yoke.
