ABSTRACT:
The hydraulic reciprocating mechanism has a housing and a piston located reciprocably in the housing. The piston and housing define a supply chamber and a return chamber. The return chamber has valve seats at either end. There is an inlet to the supply chamber for pressurized hydraulic fluid and an exhaust outlet from the return chamber. An interconnecting passage extends between the supply chamber and the return chamber. A single popper valve is located reciprocably in the return chamber and is moved by hydraulic forces between positions in which it seats on the respective valve seats. In one position of the popper valve it closes the exhaust outlet and opens the interconnecting passage to admit hydraulic fluid from the supply chamber to the return chamber. This has the result hydraulic fluid in the return chamber drives the piston in one direction. In another position of the poppet valve, it closes the interconnecting passage and opens the exhaust outlet, allowing hydraulic fluid to be exhausted from the return chamber by the piston as the piston is driven the opposite direction by hydraulic fluid in the supply chamber.
