Abstract

PURPOSE: To increase an amount of oiling to a sliding bearing by installing a spiral groove in the inner circumference of the sliding bearing for a scrol driving shaft and an oil filler port incongruent with this groove in this driving shaft, respectively, and thereby performing the oiling with a pressure differential between discharge pressure and intermediate pressure.
CONSTITUTION: An upper compressor part 2 with both scrolls 5, 6 and a lower motor part 3 are connected together a crankshaft 9 in which a main bearing 10 and an oil feeding passage 13 leading lubricating oil to a pivot receiver 12 is installed. An oil feeding passage 20 being interconnected to the oil feeding passage 13 is installed in the crankshaft 9 sliding with a lower bearing 11, and a spiral oil groove 19 is installed in this lower bearing 11 upward in a position where it will not interfere with this oil feeding passage 20. Since discharge pressure oil is fed to the sliding bearing 11 from the oil feeding passage 20 and it is interconnected to an intermediate pressure chamber 15 by way of the oil groove 19, oiling takes place with a pressure differential between discharge pressure and intermediate pressure, thus a sufficient oiling quantity is secured, thereby preventing seizure or binding from occurring.
