Apparatus for controlling working gas pressure in stirling engines |
摘要 |
Described is a working gas pressure control apparatus for a Stirling engine including a pressure boost valve provided in a minimum cycle pressure line connected to a working space by a first unidirectional valve, a pressure reducing valve provided in a maximum cycle pressure line connected to the working space by a second unidirectional valve, an operating lever for controlling the opening and closing of the pressure boost and pressure reducing valves, a compressor connected by the pressure reducing and the pressure boost valve to the cycle pressure lines, an unloading valve arranged in a circuit short-circuiting suction and discharge lines of the compressor, and a control unit for opening the unloading valve when engine rpm falls to a value lower than a preset rpm for engine idling, when the pressure boost valve is open and when the engine is operating in the steady state, thereby minimizing compressor load.
