摘要： A compressor includes a cylinder, a shaft including a main shaft and an eccentric part, a roller part having an inner circumferential surface fitted on an outer circumferential surface of the eccentric part so as to make an orbital motion, a blade part along with the roller part partitioning inside of the cylinder chamber into low and high pressure chambers, and sliding bearing parts fixed to the cylinder and including cylindrical surfaces supporting the main shaft. A relation (φDs−φDr)/2

摘要： A compressor includes a rotating shaft including an eccentric portion, a motor including a rotor connected to the rotating shaft, a compression mechanism portion driven by the motor via the rotating shaft, a first balance weight provided at one end along an axial direction of the rotor on a side facing the compression mechanism portion, and a second balance weight provided at an other end along the axial direction of the rotor. The first and second balance weights are disposed such that at least either of a center of gravity of the first balance weight or a center of gravity of the second balance weight is positioned at a preset lead angle in a rotation direction of the rotor with respect to a reference plane passing through a rotation center along an eccentric direction of the eccentric portion of the rotating shaft.

摘要： A compressor control method of controlling the vibration amplitude of a compressor equipped with a motor by using the motor is provided. The compressor is driven by the motor, and this method includes controlling, in a specific operating area, the vibration amplitude of the compressor such that the vibration amplitude is substantially constant regardless of changes in the load imposed on the motor and in the number of revolutions of the motor per unit time.

摘要： A rotary compressor includes a casing including an oil reservoir configured to store lubricating oil inside, and a compression mechanism including a reciprocator and a support. The reciprocator defines a compression chamber and reciprocating along a first direction. The support has a support surface configured to support the reciprocator. The support surface includes a first groove and a second groove formed therein, The first groove extends along a second direction intersecting with the first direction and is configured to transfer the lubricating oil to the second groove, The second groove extends from a center of the first groove toward the compression chamber along the first direction.
