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.
Claims3
A variable displacement rotary fluid energy converter comprising:
- a rotor,
- said rotor being elongate and including a longitudinal slot,
- a generally triangular chamber,
- a crank,
- said crank moving back and forth in said longitudinal slot as said rotor rotates end over end within said chamber,
- a central plate,
- said plate serving to close one end of said chamber and being free to move radially and not free to move axially,
- said plate including an elongate hole shaped as the cross-section of said rotor and surrounding same,
- said rotor being free to slide axially in said elongate hole,
- a ring,
- the outer periphery of said ring being generally triangular as the cross-section of said chamber and located in same,
- a disk,
- said disk including a hole through which said crank passes,
- said disk being free to rotate with said crank inside said ring,
- said disk including porting means to conduct fluid to and from said chamber and said longitudinal slot,
- said disk and said ring serving to close the other end of said chamber and being free to slide axially with said rotor,
- so as to vary the displacement of said chamber per revolution of said rotor.
