<p>A fluid intensifier which can use a low pressure fluid to eject fluid at a higher pressure. Another object of this invention is to provide a fluid intensifier which operates reliably with interruptible fluid sources. The fluid intensifier includes a main cylinder assembly (12), a fixed assembly (14) disposed within the main cylinder assembly (12), a reciprocating assembly (16) slideably engaged with the fixed assembly (14), and a bistable valve assembly (18). The bistable valve assembly causes incoming, low pressure fluid to be directed against one of the moving pistons (104 and 106) of the reciprocating assembly (16), to pump fluid out of regions (110 and 112) via tubes (38 and 40). At each end of a stroke, moving pistons (104 and 106) mechanically move a collar (117) of bistable valve assembly (18), which hydraulically moves a spool cylinder (118) of the bistable valve assembly (18), which redirects the incoming fluid to a moving piston (104 or 106). The bistable valve assembly (18) ensures that the fluid intensifier will operate properly even if the flow of incoming fluid is interrupted.</p> |
