Abstract

PURPOSE: To prevent a lubricant from entering a scroll lap by inserting a crank shaft into an envelop-shaped member at the center of a turning scroll projecting in a stationary scroll and by providing a seal device in the periphery of the back of the turning scroll and the main frame.
CONSTITUTION: A central part of a turning scroll 3 is formed into an envelop- shaped member A projecing into a statinary scroll 2. A crank shaft 5 is inserted into the envelop-shaped member 3A through a raial bearing 6. A seal device is provided between the periphery of the back of the turning scroll 3 and the main frame 1. With this construction the seal device can easily prevent the lubricant for the radial bearing 6, thrust bearing 11 and Oldham ring 7 from entering a scroll lap. Furthermore, the action point of radius direction force of the gas pressure is identical to the bearing action point generated by the centrifugal force of the turning scroll 3, which can prevent the generation of moment between the two action points.
