Rotary compressor

摘要

A rotary compressor for achieving efficient supply of oil into a gap between a vane and a vane groove. The rotary compressor also has a function of closing an oil supply path communicating with the vane groove when the operation of the vane stops for the sake of a variation in compression capacity. The rotary compressor includes at least one compression chamber, a vane to perform forward and rearward movements in a radial direction of the compression chamber, a vane groove to receive the vane and guide the forward and rearward movements of the vane, and an oil supply path communicating with a rear location of the vane groove. The oil supply path is opened when the vane moves forward to the compression chamber, and is closed by the vane when the vane moves rearward.
