Abstract
The double-acting type orbiting vane compressor comprises an orbiting vane having upper and lower circular vanes formed at the upper and lower surfaces of a vane plate of the orbiting vane, respectively, the orbiting vane being attached to a crankshaft rotatable by a drive unit, an upper compression unit having the upper circular vane of the orbiting vane disposed in an upper cylinder, and a lower compression unit having the lower circular vane of the orbiting vane disposed in a lower cylinder. As the orbiting vane performs an orbiting movement in the upper and lower cylinders, refrigerant gases introduced into the upper and lower cylinders through inlet tubes respectively formed at the upper and lower cylinders are compressed, and are then discharged out of the upper and lower cylinders through outlet ports respectively formed at the upper and lower cylinders.
