This paper reports a new type of Stirling engine based on a quite different principle from any ordinary engine, which releases from the problem of dead volume and makes the pressure difference between the heater and the cooler by thermodynamic process (patent obtained). In this study, the new type engine developed was carried out, whose the validity of operating prmciple was proven, and was obtained the knowledge for design of 5 kW engine to be developed in next stage.
