ABSTRACT:
A scroll compressor includes stationary and orbiting scroll members in engagement with each other. The stationary scroll member includes a stationary end plate having first and second end surfaces opposite to each other, a stationary scroll wrap protruding axially from the first end surface of the stationary end plate, a discharge port defined in the stationary end plate in the proximity of a center thereof, a generally horseshoe-shaped partition wall protruding axially from the second end surface of the stationary end plate, and spaced apart mounting legs protruding axially from the second end surface of the stationary end plate and continuous with the partition wall in such a manner that the partition wall extends between the mounting legs. Each of the mounting legs has a thickness greater than that of the partition wall and also has a height slightly greater than that of the partition wall.
