ABSTRACT:
A scroll type compressor is disclosed having a pair of scroll members which interfit with one another at an angular and a radial offset to define at least one pair of sealed-off fluid pockets of which the volume changes due to the relative orbital motion of the scroll members. The base or proximal portion of the inner end of each spiral wrap of the scroll members has an extension which increases the cross-sectional area of the base portion as compared to the upper or distal portion of the inner end. Therefore, the strength and rigidity of the inner end of each wrap, which is exposed to high temperature and high pressure is increased and the endurance of the compressor is significantly improved.
