ABSTRACT:
A locating mechanism of the fixed volute of a scroll compressor comprises a frame, a fixed volute and an orbiting volute. The frame is provided with a predetermined number of locating faces having thereon respectively a locating member which is fastened with the frame and has a sliding connection face of an arcuate construction. The fixed volute is provided with a predetermined number of shoulders which are corresponding in location and number to the locating members and are provided respectively on the outer side thereof with a sliding connection face of an arcuate construction and engageable with the sliding connection face of the locating member. The fixed volute can be caused to slide up and down along the sliding connection face of the locating member. The sliding connection face of the locating member is provided on the top thereof with a retaining portion for preventing the fixed volute from moving upward. The shoulders of the fixed volute can be fastened with the retaining portions of the locating members by a temporary member, thereby causing the fixed volute to be suspended on the locating members so as to allow the fixed volute and the orbiting volute to form therebetween a gap enabling the fixed volute to adjust itself to locate at the optimum cooperating position.
