A valve assembly comprising a valve plate having a refrigerant discharge hole, a discharge valve fixed at one end on the valve plate for opening and closing the discharge hole, and a retaining plate placed on the discharge valve, one end of the retaining plate passing through the discharge The valve is connected with the valve plate to limit the lift of the discharge valve, and an arc-shaped protrusion with a predetermined width W and height H protrudes from the bottom of the holding plate. Since the arc protrusion presses the upper portion of the discharge valve, the lift L of the discharge valve can be uniformly maintained. Moreover, the discharge valve is firmly fixed on the valve plate. Accordingly, since the operation of the discharge valve is stabilized, abnormal noise generated when refrigerant is discharged can be reduced.
