PURPOSE:To prevent the overheated refrigerant gas from flowing into the evaporator by shutting out the overheated gas, which flows out to the condenser and suction line from the compressor, while the compressor is at a standstill. CONSTITUTION:When the shaft 6 stops, the inflow line 19 formed in the cylinder 5 in No.2 discharge valve device 18 is put out of communication with the discharge hole 24 provided in the valve element 26 and, also, out of communication with the outflow line 21 leading to the discharge pipe 20. Thus No.2 discharge valve device 18 is closed. Accordingly the overheated gas while the compressor is at a standstill is prevented from flowing into the evaporator through the condenser of the refrigerating system, and thus temp. rise in the evaporator is prevented. Thereby any solenoid operated valve as in a conventional system is no more necessary as well as the power consumption can be reduced, and further risk of leakage at welds when a valve element is separately installed in the refrigerating circuit can be suppressed to assure a raised reliability. |
