REFRIGERANT COMPRESSOR

PURPOSE:To prolong the lifetime of a bearing by furnishing a means to heat part of the oil held in a compressor with the discharge gas, and by feeding this oil through an oil suction path. CONSTITUTION:In a scroll compressor as per the present invention, each revolving scroll 5 is revolved by a motor 3 through a drive shaft 7 and a rotation preventive mechanism 9, and thereby the gas inhaled from a suction hole 6c is compressed in a compression chamber partitioned between the laps of this revolving scroll 5 and a stationary scroll 6, to be discharged to a discharge pipe 15 from a discharge hole 6d. Therein the discharge pipe 15 is so arranged that immersion is made in No.1 oil sump 4a in a discharge chamber 12 followed by again introducing into the same discharge chamber. Thus the heat amount possessed by the discharge gas is conducted to the No.1 oil sump 4a by a heat conduction plate 15b mounted on the discharge pipe 15 so as to raise the oil temp. in the No.1 oil sump 4a. The oil in No.1 oil sump 4a is fed to the sliding parts through an oil suction path 11.
