Abstract

PURPOSE:To always ensure a stable oil level, by both providing a delivery gas oil separator in the delivery piping of a regrigerating cycle and communicating this oil separator to the second compressor through a return oil pipe then returning oil in said separator to the second compression element chamber. CONSTITUTION:At single operation of the first compressor 1, oil passes through a pressure equalizer check valve 1h and compression element chamber 1f to flow out to a delivery side of the compressor 1, and a compression element chamber 1d is supplied with oil from the second compression element chamber 2d while decreasing an oil level in the chamber 1d. At this time, the oil once flowing out to the delivery side passes through a delivery pipe 8, and lubricating oil in delivery gas is separated in an oil separator 9 and collected. In this way, the lubricating oil is prevented from flowing to the side of a condenser (not shown), simultaneously the lubricating oil accumulated in the separator 9 is returned again to the compression element chamber 2d through a return pipe 10, and this causes the oil to increase its amount. Accordingly, a stable oil level can be ensured even in case of restarting the second compressor 2.
