Abstract
Disclosed herein is an orbiting vane compressor incorporating an orbiting vane with oil supply function that is capable of performing more smooth orbiting movement. The orbiting vane has a compression unit comprising an orbiting vane having a boss formed in the center thereof such that the upper end of a crankshaft having an oil supplying channel formed therethrough is fixedly fitted in the boss, the orbiting vane being disposed between an annular space defined between the inner wall of a cylinder and an inner ring, and an Oldham's ring disposed at the lower surface of the orbiting vane for preventing rotation of the orbiting vane. An oil supplying hole is formed on a vane plate of the orbiting vane outside the boss for allowing oil to be supplied to the upper surface of the vane plate.
