摘要： A fluid machinery includes a rotary mechanism, an annular back pressure chamber and an oil passage. The rotary mechanism includes first and second cooperating members, each including an engaging member extending from an end plate, with the cooperating members being arranged to oscillate relative to each in order to change volumes of operation chambers formed between the cooperating members. The annular back pressure chamber is formed on the back surface side of the end plate of the first cooperating member, and communicates with an intermediate operation chamber of the operation chambers to thrust the first cooperating member against the second cooperating member. The intermediate operation chamber is in an intermediate pressure state. The oil passage is arranged to communicate an oil into the back pressure chamber to fill the back pressure chamber with the oil. The rotary mechanism can include a piston and cylinder, or can include a fixed and orbiting scroll.

摘要： In a compression mechanism of a rotary compressor, a cylinder chamber is defined by a cylinder and a second housing. A back surface side gap is defined between an end plate part of the cylinder and a flat plate part of a first housing. The first housing is provided with a communicating path and a differential pressure regulating valve. When the difference between the suction pressure and the discharge pressure is small, the discharge pressure is introduced through the communicating path to an intermediate gap whereby both an internal gap and the intermediate gap are placed at the same pressure as the discharge pressure. Conversely, when the difference between the discharge pressure and the suction pressure is great, the communicating path is made discontinuous by the differential pressure regulating valve whereby the intermediate gap is placed at an intermediate pressure lower than the discharge pressure.

摘要： A rotary compressor includes a fixed side and a movable side that is eccentrically movable relative to the fixed side. The movable side moves in response to operation of a drive mechanism, which rotates a drive shaft. The fixed side has a main bearing formed as a unitary part. A cylinder may serve as the movable side, which is coupled through an eccentric part to the drive shaft. The drive shaft is supported by the main bearing. With such an arrangement, a ring-shaped piston may serve as the fixed side, which is formed integrally with the main bearing in a front head.

摘要： A compression mechanism has a cylinder, a suction passage and a discharge passage. The suction passage of a cylinder is connected to a suction pipe. The discharge passage is open to an inner space of a sealed housing. A discharge gas is discharged through a discharge pipe. The cylinder is formed with a communicating passage extending from a suction passage to a suction pressure chamber to lead a suction gas in the suction passage into the suction pressure chamber and thereby allow a pressure of the suction gas in the suction passage to act on an outside surface of the cylinder.

摘要： The outer peripheral surface of a swing piston is formed in a non-circular form. The inner peripheral surface of a cylinder chamber is formed on a basis of an envelope curve of the outer peripheral surface of the swing piston obtained at the time of its swing. The outer peripheral surface of the swing piston and the inner peripheral surface of the cylinder chamber are formed in, e.g., an ovoid shape so that as compared to a rotary compressor in which such inner and outer peripheral surfaces are formed in a circular form, a shorter compression cycle and a longer discharge cycle is obtained during movement of the swing piston. As a result, an overcompression loss when a refrigerant is discharged in a swing compressor is reduced.
