摘要： A compressor has auxiliary (42) and main (44) oil reservoir chambers that retain lubricant oil that is separated from refrigerant in an oil separation chamber (41). A part of the auxiliary oil reservoir chamber (42) is defined by a peripheral wall (12g) of the oil separation chamber. An introducing passage (43) for introducing lubricant oil in the oil separation chamber (41) to the auxiliary oil reservoir chamber (42) is formed in the peripheral wall. The inlet (43a) of the introducing passage (43) opens to the oil separation chamber on the inner surface of the peripheral wall. The outlet (43b) of the introducing passage (43) opens to the auxiliary oil reservoir chamber (42). The main oil reservoir chamber (44) is located below the auxiliary oil reservoir chamber (42) in the direction of gravity. A drain port (45) for draining lubricant oil in the auxiliary oil reservoir chamber to the main oil reservoir chamber is formed in a bottom wall (13d) of the auxiliary oil reservoir chamber.

摘要： The present invention is a separator device (oil separation) (100) for a device (1) for compressing a gas through the use of a compression fluid, comprising a compression chamber (2) suited to generate a compressed mixture of the gas and the compression fluid, and a separation tank (7) for the removal of the lubricant fluid from the compressed mixture, a first tubular element (101) suited to be inserted between the compression chamber (2) and the oil separation tank (7) of the compression device (1), in such a way as to convey the mixture inside the tank (7). The device (100) comprises means for deviating and/or conveying the flow of the compressed mixture that are suited to convey the mixture against the inner walls of the first tubular element (101) before the compressed mixture flows out of the first tubular element (101). The invention also concerns a separation tank (7) for a device (1) for compressing a gas through the use of a compression fluid.

摘要： A compressor may include a crankshaft, a lower bearing, an oil sump, an oil pump and a pressure equilibrium tube. The crankshaft may include an oil supply passage formed therethrough. The lower bearing may rotatably support a lower part of the crankshaft. The oil sump may be disposed proximate the lower part of the crankshaft. The oil pump may include an inlet, an outlet, an intake chamber and a discharging chamber. The inlet may be positioned below a level of oil in the oil sump and in fluid communication with the intake chamber. The discharging chamber may be in fluid communication with the oil supply passage at the lower part of the crankshaft through the outlet. The pressure equilibrium tube provides fluid communication between a space above the level of oil in the oil sump and the intake chamber.
