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 supporting apparatus for a hermetic compressor supports vanes contacting to both cam faces of a dividing plate using torsion bars having square or circular cross sections, and thereby a height of the supporting apparatus supporting the respective vanes is lowered to reduce a distance between a motor device unit and a compression device unit, and accordingly, a length of the compressor in shaft direction is reduced to realize miniaturization of the compressor.

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.
