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.
