Abstract

PURPOSE: To make prevention of oil compression for example by that of the flow of lubricating oil into a cylinder for example with an oil passage closed since a valve body for opening and closing the oil passage is shaped globular so that the passage resistance of lubricating oil may be reduced and the opening of the valve body may be set small.
CONSTITUTION: When a compressor has stopped, the pressure of a plunger hole 21 communicating to a pressure passage 18 becomes lower than that of an oil passage 23 communicating to an oil separating chamber so that a plunger 22 lowers. A steel ball 25 also lowers onto oil passage 23 side due to the difference of pressure between a oil passages 23 and 24 to cancel the communication between the passage 23 and 24 so that the flow of pressurized lubricating oil 16 into a vane groove 14 and a cylinder 26 is stopped by residual discharge pressure. Thereby, liquid compression is avoided on reoperation, and reverse rotation immediately after stoppage. Since valve body is globular, the passage resistance of lubricating oil is small. Therefore, the valve body whose opening can be set small is capable of quickly closing the passage 23.
