Abstract
A control system, method and apparatus are provided in which a rotatable wedge portion which is solidly mounted on a rotatable base engages piston and cylinder assemblies as the base rotates. The wedge is rotatable through various positions relative to the base, thus providing an adjustable tilt angle and different strokes for the pistons. In another embodiment, the single wedge is replaced by a double wedge assembly.

Apparatus for controlling an axial pump having a drive shaft with an axis of rotation and a plurality of pistons parallel to and surrounding an extension of said axis of rotation beyond said drive shaft, comprising:
- a. a base member surrounding said shaft and rigidly mounted on and rotatable with said shaft, said base member including a flat surface surrounding said shaft and facing said pistons, and
- b. a first wedge member rotatably mounted on said base member between said base member and said pistons, said first wedge member having first and second opposed nonparallel flat faces, said first of said opposed faces of said first wedge member engaging said flat surface of said base member and said second of said opposed faces of said first wedge member being in driving relationship to said pistons,
- c. whereby rotation of said first wedge member relative to said base member adjusts the angle formed by said axis and said second of said opposed faces of said first wedge member to control movement of said pistons.
