<p>A discharge valve of a hermetic compressor includes a valve plate disposed on a cylinder head that draws in and discharges refrigerant according to reciprocal movement of a piston, and the discharge valve having a discharge hole formed therein through which refrigerant is discharged, a disc valve disposed adjacent the discharge hole of the valve plate, the disc valve being raised or lowered by the reciprocal movement of the piston and disc valve weight, and a stopper disposed above the disc valve, for guiding the raising and lowering of the disc valve and also for limiting the height to which the disc valve may be raised. The compressor is not subject to overload or over pressurization that may otherwise result from an elastic closing force operating in the valve, and as a result, compression efficiency is increased, while noise is decreased.</p> |
