Abstract

PURPOSE:To prevent oil from entering into a cylinder, by accumulating high pressure gas from the cylinder in a pressure accumulating tank, and by using an ejector which is actuated by the high pressure gas jetted from the tank to suck up oil pooled in a gas-oil separating filter, etc. and to return the oil into a crank casing. CONSTITUTION:In a Stirling engine, a heater pipe 2 and a cooler pipe 4 which are connected through a regenerator 3 are continuously heated and cooled, respectively, and therefore, a gas feed piston 5 and a power piston 7 are reciprocated with a phase difference therebetween which is regulated by a crank shaft 19. In this arrangement, a gas-oil separating filter 100 is disposed in a communication pipe 12 communicating the inside of the crank casing 9 with the power piston reaction chamber 10. Further, an ejector 26 is disposed in a pipe line communicating a high pressure gas accumulating tank 24 with the crank casing 9, and the suction chamber 26c in the ejector 26 is connected to an oil reserving section 100b and a distance chamber 11 through solenoid valves 27, 29. Thereby, oil sucked under the action of the ejector 26 may be returned into the crank casing.
