ABSTRACT:
Disclosed herein is a compression unit of an orbiting vane compressor having improved tight contact between a circular vane and sealing means wherein the sealing means can be easily manufactured. The compression unit compresses refrigerant gas introduced by an orbiting movement of a circular vane in an annular space defined between the inner wall of a cylinder and an inner ring. The compression unit comprises a first horizontal contact surface formed at the outer circumferential surface of the inner ring, a second horizontal contact surface formed at the inner wall of the cylinder while being parallel with the first horizontal contact surface, and a linear slider disposed in an opening formed at the circular vane for performing a linear reciprocating movement along the first and second horizontal contact surfaces.
