Abstract
A variable type compressor has a housing that houses a crank chamber and rotatably supports a drive shaft. Part of the housing is constituted by a cylinder block. Cylinder bores extend through the housing about the drive shaft. A piston is accommodated in each cylinder bore. A discharge chamber is defined in the housing and connected to the crank chamber by a pressurizing passage. An inclinable cam plate is supported on the drive shaft. The reciprocation of each piston draws refrigerant gas into the associated cylinder bore from a suction chamber and discharges the refrigerant gas into the discharge chamber through a discharge port. The displacement and the discharge of refrigerant gas is controlled by altering the inclination of the cam plate. A collection compartment is provided to receive the refrigerant gas discharged from the cylinder bores. Oil is separated from the refrigerant gas in the collection compartment. The inlet of the pressurizing passage is connected with the collection compartment to supply the separated oil to the crank chamber.
