<p>PURPOSE:To reduce the number of discharge holes and limit the source of sound to one alone and reduce noise by providing ear pieces on the anti- discharge side of a discharge lead to seal one discharge hole formed at a valve plate, providing a spring lead to push-press both sides of the ear pieces at two places. CONSTITUTION:A long recessed place 82 is formed on a side that faces a piston, at a valve plate 70 to close the opening end of the cylinder block of a hermetic compressor, and at the same time a discharge hole 79 that faces the recessed place 82 and is equipped with an annular discharge valve seat 83 is formed. Also, in the recessed place 82, a discharge lead 84 to seal the discharge hole 79 is arranged, and on the anti-discharge hole side of the lead 84, ear pieces 86 to be inserted into one end portion 87 of the recessed place 82 are formed, and both end portions of the ear pieces 86 are fixed by bending the leg piece tip 113 of a spring lead 111 and conducting push-pressing at two pieces, and the spring sheet 111 is fixed at the valve plate 70 by means of a stopper 92, and the above stopper 92, spring sheet 111 and recessed place 82 are covered with a discharge plenum.</p> |
