ABSTRACT:
An output control system for a Stirling engine includes a pressure reducing valve disposed in a highest-cycle-pressure line and connected between at least one working space and a compressor and a booster valve disposed in a lowest-cycle-pressure line and connected between the working space and the compressor. The pressure reducing valve and the booster valve are selectively actuatable by an accelerator lever attached to a feedback piston cylinder connected to the lowest-cycle-pressure line. The output control system also includes a two-way unidirectional solenoid-operated valve disposed in the highest-cycle-pressure line upstream of the pressure reducing valve and a three-way bidirectional solenoid-operated valve disposed in the lowest-cycle-pressure line downstream of the booster valve. The solenoid-operated valves are controlled by a control unit to close the highest-cycle-pressure line and connect the lowest-cycle-pressure line through a regulator valve to a source of high pressure gas when the engine is at rest.
