PISTON-EXPULSOR OF GAS STIRLING CYCLE REFRIGERATING MACHINE

摘要

FIELD: gas Stirling cycle refrigerating machines. SUBSTANCE: in starting the machine, gas from compression chamber enters chamber inside piston-propulsor through valve gears 3, thus providing for decompression. When motor is stopped, gas from chamber of piston is forced to working volume through holes of smaller diameter in body of ball 4 due to drop of pressure and due to reverse action of deformed diaphragm 9. Thus device is returned to initial position. EFFECT: enhanced reliability. 1 dwg
