摘要： A rotary compressor includes a driving shaft having an eccentric portion, a cylinder, and a roller installed on an outer circumference of the eccentric portion to contact an inner circumference of the cylinder, performing a rolling motion along the inner circumference and forming a fluid chamber to suck and compress fluid along with the inner circumference. A vane is installed elastically in the cylinder to contact the roller continuously. Discharge ports communicate with the fluid chamber. Suction ports communicate with the fluid chamber and are spaced apart from each other by a predetermined angle. A valve assembly selectively opens any one of the suction ports according to a rotation direction of the driving shaft. Compression spaces having different volumes are formed in the fluid chamber according to the rotation direction of the driving shaft such that two different compression capacities are formed.

摘要： The present invention discloses a linear compressor in which a piston is driven by a linear motor and linearly reciprocated inside a cylinder to suck, compress and discharge refrigerants. Even though load is varied, the linear compressor performs the operation in a resonance state by estimating a natural frequency of the piston and synchronizing an operation frequency of the linear motor with the natural frequency of the piston, and efficiently handles the load by varying a compression capacity by changing a stroke of the piston.

摘要： A dual capacity compressor that prevents relative movement from taking place between certain components is provided. The dual capacity compressor includes a power generating part having a reversible motor and a crank shaft inserted in the motor, and a compression part having a cylinder, a piston and a connecting rod. A crank pin is provided in an upper part of the crank shaft, eccentric from an axis of the crank shaft, and an eccentric sleeve is rotatably fitted between the crank pin and an end of the connecting rod. A key member is held at least a part of the eccentric sleeve, and held at a particular portion of at the eccentric sleeve during operation so as to positively latch the eccentric sleeve with the crank pin in both directions rotation of the motor.
