A sealing chamber is defined between the front head and the front side block. The drive shaft on which the rotor is rigidly fitted is journalled by front and rear plain bearings provided on the front and rear side blocks, respectively. The bearing on the front side has an end portion remote from the rotor enclosedly disposed in the sealing chamber. The sealing chamber communicates in a direct manner with the suction port formed in the compressor casing by way of a passage means so as to be supplied in a direct manner with suction refrigerant having a low temperature and a low pressure.
