Rotary vane-type compressor with discharge passage in rotor

Abstract

A compressor, particularly such suited for use in motor vehicles, especially passenger cars, for instance, in the air conditioning systems thereof, includes a stator including a housing bounding an internal space accommodating a rotatable body of a rotor. An internal surface of the housing and an external surface of the rotatable body together form at least one compression space of a varying radial dimension as considered in the circumferential direction. The rotary body is provided with a plurality of recesses each of which partially receives a respective vane for reciprocation in contact with the internal surface of the housing, such that the vanes subdivide the compression space into a plurality of compartments. The medium to be compressed is sequentially admitted into the respective compartments through respective inlet openings provided in the stator. The compressed medium is discharged from the respective compartments through a passage provided in the interior of the rotary body. This passage communicates with a discharges space arranged at one axial end of the compressor and communicating with a discharge port.
