A fluid actuator for a hydraulically powered rotatable gripping device which combines a fluid pressure or force multiplication with the capability of a physical separation of the rotating jaws and the fluid power source to permit rotation of the jaws and any gripped object while maintaining clamping or gripping pressure.
Claims14
Actuating means for rotatably mounted gripping apparatus comprising:
- (a) a fluid supply and pressuring means;
- (b) a transmission mechanism means for translating said pressurized fluid into a force moving across a physical boundary and for translating said force back into pressurized fluid once across said boundary, said mechanism comprising:
- (i) a first component in fluid communication with said supply comprising a constituent moveable in response to said supply and pressurizing means,
- (ii) a second component rotatably mounted with said gripping apparatus, said second component comprising a moveable constituent capable of alignment with said moveable constituent of said first component, said second component in fluid communication with said gripping apparatus for actuating said gripping apparatus by fluid pressure generated in response to movement of said second moveable constituent component in response to movement of said first moveable constituent component when said first and second components are aligned and when said first component is supplied with fluid and pressurized.

Actuating means for rotatably mounted gripping apparatus comprising:
- (a) signal means;
- (b) transmission means for translating said signal means across a physical boundary comprising:
- (i) a first component in communication with said signal means comprising a constituent movable in response to said signal means;
- (ii) a second component rotatably mounted with said gripping apparatus, said second component comprising a movable constituent capable of alignment with but not connected to said movable constituent of said first component, and said second component in communication with said gripping apparatus for actuating said gripping apparatus in response to movement of said second moveable constituent component in response to movement of said first moveable constituent component when said first and second components are aligned, and when said movable constituent of said first component is moved in response to said signal means.
