PURPOSE:To check the stirring of a discharge refrigerant inclusive of oil as well as to prevent the oil from being discharged to a refrigerating cycle, by installing both main and auxiliary balancers consisting of heterogenous metals largely different in density, in the lower part of a rotator of a motor element symmetrically with the rotator center shaft. CONSTITUTION:A compressor bearing the above caption compresses the refrigerant sucked in a cylinder 8 by rotating a piston 7 of a compressor element 6 by the motor element 4 housed in a hermetically sealed vessel 1, and it pushes a discharge valve 12 open, discharging the high pressure refrigerant into the hermetically sealed vessel 1 via a discharge hole 11, a muffler 13 and a blowout hole 14, and discharges it to a refrigerating cycle from this vessel 1. And, at this time, rotation is balanced by the balancer 16 is installed in the lower part of a rotator 3. In a suchlike compressor, the balancer 16 is formed with both main and auxiliary balancers 17 and 17b formed with heterogeneous metals largely different in density symmetrically with a center shaft of the rotator 3. With this constitution, the refrigerant contained oil is hard to stir, thus the desired aim is achieved. |
