ABSTRACT:
A scroll-type compressor including stationary and orbiting scrolls housed in a shell. A first frame, also housed in the shell, receives a portion of the orbiting scroll. The stationary scroll is fixed to the first frame, and a second frame is further mounted in the shell. A balancer chamber is formed between the first and second frames. A main shaft having a balancer is housed in the balancer chamber rotatably. The main shaft includes an enlarged diameter portion on one end of the shaft which is attached to the orbiting scroll and a small diameter portion on the end of the shaft which is attached to the orbiting scroll and extending between the first frame and the second frame for driving the orbiting scroll. A first bearing is disposed between the main shaft in the first frame for supporting the main shaft at a position between the orbiting scroll end of the shaft. A second bearing is disposed between the main shaft and the second frame for supporting the main shaft at a position proximate opposite the end of the shaft. The main shaft has an axial oil passage that extends from a bottom portion that is in contact with an oil pan at the bottom of the shell to an eccentric hole in the top of the shaft that is adapted to receive the orbiting scroll shaft. Upon rotation of the shaft, oil is pumped up to the eccentric hole. An Oldham coupler at the top of the main shaft and motor mounting legs have oil return holes and passages that assure proper lubrication of the compressor.
