  • Patent number: 7275561
    Abstract: A discharging valve assembly for a reciprocating compressor includes a discharging cover coupled with a front frame so as to cover a cylinder in which a piston is inserted; a discharging valve inserted in the discharging cover, and opening/closing an inner space of the cylinder where gas is compressed; and an unbalancedly and elastically supporting means elastically supporting the discharging valve so that contact pressure applied to the discharging valve when the valve comes in contact with the contact surface of the cylinder is unbalanced. Accordingly, the discharging valve assembly can improve discharging efficiency of gas compressed in the cylinder and discharged, and can minimize noise generated when the discharging valve comes in contact with the cylinder while moving.

  • Patent number: 6793470
    Abstract: A spring support structure for reciprocating compressor having a frame unit elastically supported inside a closed container; a reciprocating motor fixed at the frame unit; a compression unit having a piston combined to an armature of the reciprocating motor and a cylinder to be fixed at the frame unit; and a spring unit supporting a spring support provided at the armature or the piston and guiding a reciprocal movement of the piston. The spring unit includes a plurality of front springs supporting one side of the spring support in parallel and a plurality of the rear springs supporting the other side of the spring support. Because the front and rear springs elastically supporting both the armature and the piston are arranged in parallel to overlap with each other for a certain range, the horizontal length of the spring is reduced, resulting in a compact compressor.

  • Patent number: 6533064
    Abstract: A noise reduction device has a side branch silencer. The side branch silencer is formed within a discharge valve assembly which includes is divided into a discharge muffler, a gasket, a discharge valve piece and a valve plate. The side branch silencer is provided with a cutout formed through the gasket to communicate with a discharge passage formed through the gasket. The cutout is blocked vertically by both a lower surface of a muffler plate of the discharge muffler and an upper surface of the discharge valve piece.

  • Publication number: 20030035589
    Abstract: The present invention relates to a quantization/dequantization method by making a dynamic adaptive table and an apparatus thereon. The present invent provides a quantization method by making a dynamic adaptive table, the method including the steps of: extracting complexity of randomly inputted visual data; generating a quantization table having a lower coefficient value for a high frequency in the quantization table as a degree of the extracted complexity gets higher; and transmitting the visual data after performing a discrete cosine transform process and a quantization process by the quantization table upon the visual data.
