Abstract

PURPOSE: To nullify gas leakage and enhance volume efficiency and refrigerating capacity by feeding the oil in an oil sump to a refrigerant injection pasage at a bearing through utilization of the differential pressure between the refrigerant pressure and the internal pressure of the case.
CONSTITUTION: A bearing 5 is provided with an oil hole 13 in communication with a refrigerant injection passage 11. When the refrigerant is sent to the injection passage 11 from injection pipe 14, the oil in oil sump 15 is sucked in the injection passage 11 through a pipe 14 and oil hole 13 by means of differential pressure between the refrigerant pressure in injection passage 11 and the internal pressure of enclosure 2, and ejected into a cylinder 1 together with the refrigerant. As a result, the gas leakage under compression stroke is nullified by oil seal, and volume efficiency and refrigerating capacity can be thus enhanced.
