PURPOSE:To obviate the need for a conventional long pressure passage and im- prove the workability and the producitivity by interposing a throttle mechanism consisting of sealing packings etc. in the pressure passage for introducing the compressed gas pressure into the lubricating oil feeding control valve mechanism for a vane. CONSTITUTION:A compressor is equipped with the valve mechanism consisting of the steel ball valve 25 which feeds lubricaing oil to a vane when the compressor operates and cuts-off feeding when the compressor stops operation, and said valve mechanism feeds the pressurized oil in an oil separating chamber 10 through passages 19 and 20. While, the discahrge gas pressure is introduced into a plunger hole 21 through an intake port 17 and pressure passages 18a and 18b in order to ON/OFF-operate the steel ball valve 25, and the sealing packing 30 in the form of a throttle valve for damping the pulsation of the discharge pressure is interposed in the pressure passage. Therefore, the passages 18a and 18b which are formed of the groove 32 of the packing 30 can be set fairly throttled state. |
