Patent ID: 7361004

Claim:
A compression unit of an orbiting vane compressor, comprising: a circular operation space formed in a cylinder, the operation space having opposite ends separated from each other by a closing part; a circular vane disposed in the operation space for performing an orbiting movement to compress refrigerant gas introduced into the operation space, the circular vane having opposite ends separated from each other by partially cutting the circular vane; and a sealing unit brought into contact between one end of the circular vane and the closing part, the sealing unit comprising: a linear slider disposed in the operation space, which has linear slide contact surfaces, for performing a linear reciprocating movement while one end of the linear slider is in contact with the end of the circular vane; and a pressurizing member disposed in the operation space adjacent to the other end of the linear slider for applying pressure to the linear slider such that the linear slider is brought into tight contact with the circular vane.
