Abstract
A vane-type rotary refrigerant compressor adapted for use in an air conditioning system is disclosed which includes a rotor fixed on a drive shaft for rotation therewith and disposed in an elliptical chamber of a cylinder block which is enclosed by a housing and whose axial ends are closed by front and rear side plates. The rotor has a plurality of slots in which vanes are slidably received so that a plurality of compression chambers are formed during the operation of the compressor. An oil separator compartment is defined by the housing and the rear side plate, communicating with a discharge chamber into which compressed refrigerant is discharged. In the rear side plate is formed a discharge passage establishing communication between the discharge chamber and the oil separator compartment. The discharge passage has a restricted portion and a bend so as to provide resistance against the flow of the compressed refrigerant for damping its pulsating stream.
