Abstract
A volumetric fluid compressor or a so-called scroll type compressor is provided in which a rotary shaft is placed centrally in the front side of a housing, a helical portion of a movable scroll member is contacted eccentrically with a helical portion of a fixed scroll member, the helical portion of the movable scroll member is rotated about the axis of the rotary shaft to which the movable scroll member is mounted with an offset, in such a manner that a closed space defined between the two helical portions may be contracted towards the center for compressing the refrigerant gas which may thus be discharged towards rear from the center of the fixed scroll member. A stationary member for preventing the rotation of movable scroll member is secured in the housing about centrally of the longitudinal axis of the housing for defining a suction chamber towards the front side of the housing and a working chamber on the rear side of the housing, the fixed and movable scroll members being provided within the working chamber. A suction port is formed in the housing directly above the rotary shaft for introducing the fluid to be compressed into the suction chamber whereas a plurality of suction passageways are formed in the stationary ring for introducing the fluid to be compressed from the forward side suction chamber into the rear side working chamber.
