PHA 40.593 02.04.1991 ABSTRACT: Hydraulically propelled pneumatically returned valve actuator. An actuator which is used, for example, to operate an internal combustion engine poppet valve is configured to open the poppet valve by means of a high pressure hydraulic fluid. This fluid powers the actuator piston and, at the same time, compresses air to accomplish both damping of the piston and conversion of the kinetic energy of piston translation into potential (pneumatic) energy. The actuator is held or captured in the second or valve-open position by a hydraulic latch and when released, is returned by the stored pneumatic energy to its initial position. Damping of the returning actuator piston is accomplished by a separate adjustable pneumatic orifice arrangement to assure gentle seating of the poppet valve.
