Abstract

PURPOSE: To prevent jumping phenomenon of a vane by a method wherein a valve actuated by a pressue difference arising across a discharge valve is provided in a lubricating oil passage, which operates to open the oil passage at running and close at shutdown, thus securing a supply of the lubricating oil during running of a compressor.
CONSTITUTION: In a valve mechanism 30 provided uniformly with an end plate 4, since a pressure passage 44 is kept open to a high-pressure space in a cylinder 2, a plunger 36 is pushed upward and a spherical valve 35 is kept open at the time of operation of a compressor 1. A lubricating oil can therefore be made serving for pressuring a vane 28 continuously by rotation of a rotor 5, the so-called jumping action of the vane 28 is eliminated thereby, and an abnormal wear can be prevented accordingly. When the compressor stops, furthermore, the valve mechanism 30 closes quickly to interrupt the lubricating oil to a vane groove, and both refrigerant gas and lubricating oil do not come to flow from the high-pressure side to the low- pressure side, thus preventing an oil compression phenomenon from arising at restart-up.
