摘要： PURPOSE: An apparatus for reducing suction loss of a reciprocating compressor is provided to reduce suction loss of refrigerant gas. CONSTITUTION: A piston(120) has a gas channel formed therein and connected with a suction tube of a casing to guide refrigerant gas to a compression space of a cylinder. The gas channel comprises a suction channel(121) penetrating in longitudinal direction of the piston; a suction penetrating port(122) connected with an outlet side of the suction channel and perforated to a front end side of the piston; and a suction guiding part(123) placed between the suction channel and the suction penetrating port, and formed to be tapered so as to get narrower from the suction channel to the suction penetrating port. Refrigerant gas introduced into the gas channel passes the suction channel and is discharged along the suction guiding part through the suction penetrating port as channel resistance is reduced thereby. Alternatively, the suction guiding part is extended to the front end side of the piston to minimize length of the suction penetrating port, or is formed from a starting end of the suction channel to an end of the suction penetrating port.

摘要： PURPOSE: An apparatus for reducing noise of a reciprocating compressor is provided to reduce knocking sound of a discharge valve. CONSTITUTION: An apparatus includes a cylinder(110) inserted and fixed to a frame unit, forming a compression space(P) formed therein, and having a plurality of buffer grooves(112a) formed on a front end side(112) thereof; a piston(42) slid into the compression space of the cylinder, and linearly reciprocating together with a mover of a reciprocating motor to vary volume of the compression space; and a discharge valve assembly(120) mounted on the front end side of the cylinder to open and close the compression space of the cylinder when the piston reciprocates. The buffer grooves are formed on the front end side of the cylinder in circumferential direction at regular intervals. Severe collision of a discharge valve(122) of the discharge valve assembly against the front end side of the cylinder due to sudden closing of the discharge valve is prevented by force of compressed gas charged in the buffer grooves during discharge of the compressed gas.

摘要： A reciprocating compressor, wherein a flange unit connected to the mover constituting the reciprocating motor is installed on the piston constituting the compressing unit, the distance between the piston flange unit and the front frame of the frame unit is shorter than that of the between the piston flange unit and the reciprocating motor. In the process of being transmitted the linear reciprocal movement driving force of the reciprocating motor and compressing the gas in the compressing unit, the stability of the compressor is raised by preventing the components moving together with the mover of reciprocating motor from impacting with other components by the displacement generated by compression force applying the piston constituting the compressing unit. Also, the size of compressor can be scaled down by compactly constituting the components.

摘要： PURPOSE: A compressor is provided to form minute lubricant grooves in the inner circumference of a shaft hole where a crank shaft is inserted and the outer circumference so that the compressor efficiency is improved by steadily supporting the crank shaft while reducing a frictional area between the crank shaft and the shaft hole. CONSTITUTION: A compressor comprises a motor driving unit and compression unit. The motor driving unit generates the power. The compression unit pressurizes refrigerant by reciprocating a piston in a cylinder by the motor driving unit. A plurality of lubricant grooves(14b, 14c) is formed in the outer circumference of the piston or the inner circumference of the cylinder. A front side bearing unit and rear side bearing unit are formed in both ends of a longitudinal direction of the piston to be slid and contacted to the cylinder. The lubricant groove is formed in the outer circumference of one or more bearing units between the both bearing units.
