CONTROL VALVE FOR COMPRESSOR

摘要

The present invention relates to a control valve for a compressor for pressurizing refrigerant sucked from a suction chamber using a plurality of reciprocating pistons connected to an inclined plate, which is arranged in a crank chamber, and discharging the refrigerant into a discharging chamber. The present invention provides a control valve for a compressor, comprising a main body of the valve having a control path formed so that the crank chamber can intercommunicate with the discharging chamber; a driving part included in the main body of the valve; and an air supply valve including a sleeve, arranged on the inner side surface of the main body of the valve to open and close the control path via the driving part, wherein a contact part of the main body of the valve and the end part of the sleeve, which face each other, have corresponding shapes to be able to slide. The control valve for a compressor according to the present invention not only prevents noise generated by vibration but also prevents the leakage of the refrigerant by enhancing the performance of sealing via surface contact when the control valve is closed.
