Abstract

In a sealed type scroll compressor including an intermediate pressure chamber in which a pressure intermediate in magnitude between a discharge pressure and a suction pressure prevails, a bearing device including a roller bearing and a plain bearing mounted on a frame for supporting a shaft section of a crankshaft. To reduce application of unsymmetrical load to the bearings and prevent an increase in a bearing friction loss, the roller bearing is located in a position close to a crank section of the crankshaft and the plain bearing is located in a position remote from the crank section.
