Abstract

PURPOSE: To prevent reduction in an achievement coefficient during operation and to obtain a good pressure balance during a shutdown by providing a balance groove on an end surface of a cylinder block, by forming a muffler chamber and an oil reserving chamber, and by making an opening end of the oil reserving chamber faced by the balance groove.
CONSTITUTION: A lubricant supplied from an oil pump during operation flows out of the tip end of a bearing 6 through an interval between a shaft 4 and a main bearing 6 and is guided to an oil reserving chamber 16, and the lubricant which has been collected is guided by a balance groove 12 and fills it. Thus, refrigerant gas is prevented from flowing into a cylinder chamber 5a through the balance groove 12, which prevents reduction in an achievement coefficient during operation. Also, during a shutdown, as there is no oil supplied form the oil pump, the lubricant which has been collected in the balance groove 12 flows down along it, and high pressure refrigerant gas can be guided into the cylinder chamber 5a from the balance groove 12, which achieves a good balance between the high pressure side and the low pressure side.
