Abstract

PURPOSE: To prevent the deterioration of refrigerating capacity and the cracking of a valve due to the oil compression, by opening/closing the outlet of pressure equalizing piping for equalizing the pressures in the crank chamber for each compressor through the operation of an oil regulation valve for regulating the pressure of oil to be supplied to the sliding section of each compressor.
CONSTITUTION: A piston 25 can move in a cylinder 22 where its one end surface is continuously biased through a coil spring 26 toward an oil returning pipe 20. During operation of the compressor, the bypassed oil is returned through the oil returning pipe 20 and an oil returning port 24 into the crank chamber, as shown by an arrow, while the pressure in the crank chambers 9, 10 are equalized. Since an oil pressure regulation valves 18 associated with a pressure equalizing ports of compressors 1, 2 are always in this state during the operation of said compressors 1, 2, the oil is returned into both crank chambers 9, 10 while the pressures in both crank chambers 9, 10 are equalized.
