PURPOSE:To eliminate conventional piston thus to improve the thermal efficiency and the reliability by encapsulating the working fluid in an enclosed container and providing a heater and a cooler while separating the inner space of said container into two through a partitioner having a communicating hole. CONSTITUTION:Upon lifting of a displacer 21, the pressure in the expansion space 22 will go higher than that in the compression space and the differential pressure will cause motion of the working fluid in the expansion space 22 through a heater 24, a regenerator 25 and a cooler 26 into the compression space 23. Consequently, the volume of high temperature working fluid in the expansion space 22, a flow path 27 and the heater 24 will decrease while the volume of low temperature working fluid in the compression spaces 23, 18, a flow path 27' and the cooler 26 will increase. Upon lifting of the displacer 21, pulsating pressure is produced in the working space to lift a flexible partitioner 17 having a hole 20. Consequently, the working fluid in the working space will perform work against the flexible partitioner 17 which will perform work against spacific load 33. |
