Abstract

PURPOSE: To prevent lack of oil in an oil groove formed in a shaft fitted in a roller, by communicating the slide surface part between a bearing and a roller to the low pressure side through a communication passage so that high pressure gas leaking through the slide surface part is introduced to the low pressure side.
CONSTITUTION: A communication hole 14 for communicating the slide surface part 13 between a main bearing 6 or an auxiliary bearing 7 and a roller 10 with the suction side of a cylinder 3 is formed in the inner wall of the main bearing 6 and the auxiliary bearing 7 on the cylinder side 3. During compression high pressure gas leaking through the slide surface part 13 between the main bearing 6 or the auxiliary bearing 7 and the roller 10 is led to the low pressure side through the communication passage 14. Accordingly, high pressure gas leaking through the slide surface part 13 may be prevented from flowing into the inner diameter side of the roller 10 so that lubrication oil in an oil groove 11 in a shaft 4 fitted in the roller 10 is prevented from being driven into a closed casing. Thereby it is possible to prevent lack of oil in the oil groove 11. Further, the communication passage 14 may be formed as a communication groove 16, and a gas sump in the form of a ring-like recess may be formed in the intermediate part of the passage 14.
