Abstract

PURPOSE:To prevent inversion caused by compressed oil and the interruption of operation by providing an opening and closing valve actuated by the difference in pressure in the passageway of lubricating oil in such a manner that the passageway is opened when a compressor is operated, and closed when the operation is interrupted. CONSTITUTION:As for the pressure at an outlet of cooling medium 7 located in front of a vomiting valve 8, or the passageway 20 and the pressure produced after the medium has passed through the vomiting valve 8, or that in space in a spring 26, the pressure in the passageway 20 is higher when the compressor is rotating. Since there occurs a difference in force which both the ends of a valve body 24 receive, the valve body 24 moves downward against the force of the spring 26, and a vane 5 is forced to touch a cylinder 2 tightly because the passageway 22, semicircle groove 25, passageway 21 and circle groove 17 are interconnected. Next if the rotation of the compressore is interruped, the vomiting valve 8 is immediately closed. Consequently, the pressure in the passageway 20 is lowered in comparison with that it the spring 26, and thus the valve body 24 moves upward, interrupting the flow from the passageway 22 to semicircle groove 25, passageway 21 and circle groove 17. Therefore, the penetration of lubricating oil 23 into the cylinder 2 and its inverting flow into the rotor 1 can be prevented.
