ABSTRACT:
A scroll compressor locks the stationary scroll into the compressor housing without the use of any separate fasteners that pierce the housing. Cooperating locking ramps on the housing and scroll end plate wedge together when the two are relatively turned to pull the lower surface of the end plate tight against an annular shelf in the housing. A seal is also compressed, a seal that serves as a spring to maintain the ramps latched together. Staggered cylindrical baffle walls on the underside of the end plate and inside of the rear head give an exhaust chamber that is muffled as well as sealed.
