<p>PURPOSE:To prevent a temperature rise of delivery gas by sufficiently supplying oil, separated from an oil separator chamber, to a low pressure part or a suction pipe in a compressor, improving lubrication of a sliding part in the compressor, and also suppressing an amount of high pressure gas from leaking to a side of the low pressure part or suction pipe in the compressor in the case of oil disappearing in an oil reservoir chamber. CONSTITUTION:An oil reservoir chamber 34 for temporarily storing oil, separated in an oil separator chamber 29, is provided, and an intermediate chamber 37 is provided in a lower part of the oil reservoir chamber 34. The intermediate chamber 37 communicates with the oil reservoir chamber 34 through a throttle hole 38, and a valve element 40, which opens/closes an inlet of an oil return passage 39 to provide elasticity, is arranged in a side of the intermediate chamber 37 of the oil return passage 39 for connecting the intermediate chamber 37 to a swash plate chamber 8 in a compressor. In the case that oil disappears in the oil reservoir chamber 34, the valve unit 40 closes the oil return passage 39 by a pressure of gas supplied to the intermediate chamber 37.</p> |
