  • Patent number: 4523895
    Abstract: A fluid intensifier characterized by a bistable control mechanism which "remembers" the point in the operating cycle it is in. The bistable control mechanism controls the movement of a reciprocating assembly located within a main cylinder assembly. The reciprocating assembly co-acts with a stationary assembly to pump high pressure fluid from the main cylinder assembly. The fluid intensifier can be powered by an interruptable fluid source since the fluid intensifier will resume operation from its stopping point when fluid pressure is reapplied.
