Claim 0:
1. A pinch valve assembly comprising:
opposing pinch members for pinching oppositely against a fluid conduit sleeve;
a hydraulic displacement mechanism acting on the opposing pinch members, the hydraulic displacement mechanism comprising:
at least one hydraulic displacement push rod coupled to a first pinch member at one end and penetrating a hydraulic reservoir at an opposite end to displace hydraulic fluid therein;
at least one pinch member push rod penetrating the hydraulic reservoir at one end and coupled to a second pinch member at an opposite end such that, in use:

as the first pinch member moves towards the sleeve to pinch against one side of the sleeve, the at least one hydraulic displacement push rod moves into the hydraulic reservoir to displace hydraulic fluid therein to cause the pinch member push rod to be pushed from the hydraulic reservoir under pressure to push against the second pinch member to pinch against an opposite side of the sleeve.
