ABSTRACT:
An elongate rotor operated by a crank and rotating within a generally triangular chamber to act as a positive displacement pump or fluid motor. Sliding the rotor axially through a close-fitting hole in a plate which is free to move radially but not axially causes the displacement of the triangular chamber to vary. System fluid pressure may be used to vary the displacement.
