    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 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： A rotary fluid machinery includes a fixed member, a drive shaft driven and rotated about a rotation axis, a movable member, a movable member support part and a reverse moment generating mechanism. The movable member is rotatably mounted at the drive shaft with its center being eccentrically disposed relative to the rotation axis, with the movable member and the fixed member forming a fluid chamber. Revolution of the movable member changes the volume of the fluid chamber. The movable member is configured to swing in association with its revolution. The reverse moment generating mechanism generates a moment in a reverse direction about the rotation axis relative to a moment about the rotation axis caused by the revolving movement of the movable member.
