摘要： A rotary compressor includes a compression mechanism, an electric motor and a controller. The compression mechanism includes a piston and a cylinder having two cylinder chambers. The electric motor is configured to change volumes of the cylinder chambers by eccentrically moving the cylinder and the piston relative to each other. The controller is configured to change an output torque of the electric motor in accordance with a variation in a load torque of the compression mechanism in one turn of rotation.

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 compressor includes a compression mechanism having lower and upper stage compression chambers. Refrigerant compressed in the lower-stage compression chamber is further compressed in the higher-stage compression chamber. An intermediate injection pipe is arranged to inject refrigerant between the lower-stage and the higher-stage compression chambers. The compression mechanism includes at least one fixed member having a fixed end plate, and at least one movable member having a movable end plate section facing the fixed end plate with at least one of the compression chambers interposed between the end plate sections. At least one intermediate back pressure chamber is formed to face a back surface of the movable end plate section. The intermediate back pressure chamber communicates with a discharge side of the lower-stage compression chamber, and is arranged such that internal pressure of the intermediate back pressure chamber acts on the movable end plate section.

Each of the two piston mechanisms includes a cylinder member with a cylinder chamber, a piston member housed eccentrically in the cylinder chamber such that the cylinder chamber is partitioned into first and second compression chambers. A phase difference of 90 degrees in volume change is made between the cylinder chambers of the two piston mechanisms. A movable one of the cylinder and piston has a first surface facing one of the first cylinder chambers and a second surface facing one of the second cylinder chambers, with a surface area of the first surface being equal to a surface area of the second surface.

摘要： A rotary compressor includes a cylinder having an annular cylinder space, a piston eccentrically disposed relative to the cylinder, and a drive shaft (53) connected to the piston. The piston has a piston portion eccentrically rotatable relative to the cylinder, and a piston end plate closing the cylinder space. The cylinder has an end plate storage space storing the piston end plate in an eccentrically rotatable manner. The cylinder space forms a main cylinder chamber, and the end plate storage space forms a sub-cylinder chamber.
