Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a hydraulic or pneumatic drive system, and a fluid motor (12) and a fluid pump (10) therefor.SOLUTION: In such a system, rotation motion is converted to reciprocating motion or vice versa. In particular, motion conversion means comprises a portion extending continuously and circumferentially around a central axis and extending in part longitudinally relative to the central axis, and linking means, wherein the portion and the linking means are relatively rotatable about the central axis and one of the linking means and the portion is fixedly coupled to piston means, wherein the linking means and the portion are configured to cooperate whereby the reciprocating movement of the piston means causes relative rotary motion of the other of the portion and the linking means about the central axis. The other of the portion and the linking means is coupled to sleeve means to cause rotation thereof.SELECTED DRAWING: Figure 2
