Abstract
PURPOSE: To both simplify the constitution around vanes and improve operational reliability of the vane in a compressor having a sliding vane expander, by supplying a gas state medium into a cylinder, partially guiding said medium to a rear end of the vane and applying back pressure to the vane.
CONSTITUTION: A solenoid valve 16 is closed to operate a feed liquid pump 14 and heat a gas state refrigerant flowing in a refrigerant passage 10 by a heater 15. In this way, the heated refrigerant is gradually confined between the pump 14 and the valve 16 to increase internal pressure. Then the gas state refrigerant partially passes through an introduction line 20 and groove 27 and is fed to pressurizing chambers 24a... to further apply pressure to the rear end of each vane 25..., and each of the vanes 25... advances then its point end is adapted to the inner wall face of a cylinder 22, thus the rotary torque generating preparation form of an expander 3 can be achieved. Further for internal pressure in the passage 10 to become at least a prescribed value, the valve 16 is opened, and a rotor 23 is rotated by expansion of the refrigerant, then a rotary piston in a compression mechanism part 4 can be driven through a shaft 5.
