Abstract
A scroll type compressor having a front housing, a rear housing, an intermediate outer shell portion arranged between the front and rear housing to form an integral stationary scroll element having a stationary end plate and a stationary spiral member, a movable scroll element having a movable end plate and a movable spiral element and being engaged with the stationary scroll element to define a plurality of compression chambers shifting and reducing in volume to compress refrigerant gas, containing therein an oil component, in response to an orbiting motion of the movable scroll element, a suction port formed in the intermediate outer shell portion to directly introduce the refrigerant gas into the compression chambers, and a discharge chamber in which the refrigerant gas after compression is discharged from the compression chambers. The rear housing having an oil-separating chamber for separating the oil component from the refrigerant gas after compression and an oil-storing chamber for storing therein the separated oil to be supplied to the interior of the front housing via an oil passage formed in the intermediate outer shell to cool and lubricate movable elements and portions of the compressor.
