Abstract: A compressor is provided in which a rotary member suspended on a stationary member is rotated to compress a refrigerant. The rotary member is suspended on a first stationary member and rotatably supported on a second stationary member spaced apart from the first stationary member, to thereby achieve structural stability, improve operation reliability, and reduce vibration. The components can be easily centered and assembled with an excellent assembly property. In addition, a mounting structure of an elastically-supported vane is improved to ensure lubrication performance and operation reliability. Moreover, a mounting structure of a roller-incorporated vane is improved to reduce vibration and prevent refrigerant leakage, which leads to high compression efficiency.

The rotary member is suspended on a first stationary member and rotatably supported on a second stationary member spaced apart from the first stationary member, which achieves the structural stability and allows the components to be easily centered and assembled. A refrigerant suction passage and a refrigerant discharge passage are such that the refrigerant may be sucked and discharged without a valve.

Abstract: A compressor is provided in which a rotary member is suspended on a stationary member and rotates to compress a refrigerant. In the stationary member, top and bottom ends of a stationary shaft are fixed to improve structural stability and assembly properties. Bearing covers are provided on a contact portion of the stationary member and the rotary member, such that the rotary member may rotate when suspended on the stationary member, which stabilizes operation. In the rotary member, a vane is integrally formed with a roller and mounted on a vane mounting hole of a cylinder-type rotor. Although, the rotary member is provided on an outer circumferential surface of the stationary member, suction and discharge operations of the refrigerant are performed in an axial direction, which lowers product height. Oil stored in a hermetic container is supplied to a lubrication passage provided between the stationary member and the rotary member.

Abstract: The present invention relates to a reciprocating compressor. The reciprocating compressor includes a latching unit by which a piston is reciprocated by two times a total eccentric amount obtained by adding an eccentric amount of an eccentric portion to an eccentric amount of an eccentric sleeve in a power mode, while the piston is reciprocated by two times the eccentric amount of the eccentric portion in a saving mode, accordingly the piston can have an upper dead point same in the power mode and the saving mode, thereby reducing a dead volume between the piston and a discharge valve and increasing a variable ratio of a cooling capacity of the compressor in the saving mode.

This reduces the vibration and prevents refrigerant leakage to improve the compression effect. Although the rotary member is provided on an outer circumferential surface of the stationary member, it is possible to perform the suction and discharge of the refrigerant in the axial direction. This can lower the product height.

Abstract: A vane supporting apparatus for a hermetic compressor elastically supports vanes contacting to both cam faces of a dividing plate with thin torsion coil springs, and forms curved surface portions on upper ends of the vanes where the torsion coil springs are contacted, and thereby, height of the supporting apparatus supporting the respective vanes is reduced to miniaturize the compressor, and also, to prevent contacted portions between the vanes and the torsion coil springs from being worn away.

Abstract: A compressor is provided which minimizes impact noise and abrasion between a Z-plate of the compressor and vanes formed in the compressor. Ends of the vanes formed in the compressor contact sides of the Z-plate, and the motion and surface configuration of the Z-plate cause the vanes to move reciprocally and to section compression spaces within the compressor into a suction area and a compression area. Due to the curvature of the surfaces of the Z-plate, the vanes remain in constant contact with the surface of the Z-plate, which allows for smooth transition phases and a subsequent reduction in impact noise and abrasion between the vanes and the Z-plate.

Abstract: A compressor includes a Z-plate which sections an inner space of a cylinder into a plurality of compression spaces to suck, compress and discharge a fluid and vanes being in contact with both sides of the Z-plate to be moved reciprocally to section each compression space into a suction area and a compression area. The Z-plate includes a curved portion formed with a particular function for the both sides being in contact with the vane, a plane portion formed around an inflection point of the curved portion including the inflection point, and a gentle portion formed round between the curved portion and the plane portion. The vanes are maintained in a state of constantly contacting the cam surface of the Z-plate, so that an impact noise caused between the vane and the Z-plate can be prevented.

Abstract: A vane structure for a compressor comprises: a Z-plate located in a cylinder assembly for dividing an inner space of the cylinder assembly into a plurality of compression spaces and notated by a driving unit to suck, compress, and discharge fluid; and vanes undergoing reciprocating movements by being contacted to both surfaces of the Z-plate for dividing the respective compression space into a suction area and a compression area, wherein the vane includes a vane roller which is rolling contacted to the Z-plate to reduce a friction resistance between the Z-plate and the vane, and thereby an abrasion can be minimized, a noise generation can be reduced, life spans of components can be increased, and a reliability of the compressor can be improved.

Abstract: A compressor including a cylinder assembly having a compression space through which suction passages and discharge passages are connected, a rotation driving unit inserted into the compression space of the cylinder assembly to transfer a rotation force, a slant compression slanted plate installed in the compression space to divide the compression space into at least two parts and rotating by being connected to the rotation driving unit, and vane units attached on both sides of the slant compression plate to classify the partitioned compression space into a suction space and a compression. With this construction, a vibration and a noise can be reduced and a stable driving force can be obtained even with a relatively small capacity electric motor. In addition, since fluid can be compressed and discharged simultaneously in both sides of the slant compression plate, an excellent compression performance can be accomplished in a simple structure.
