However, as shown in FIG. 3, the above-mentioned cover gasket mounting device for a hermetic compressor uses a flat cover gasket 17, so a ring embankment for suction sealing is provided on the outer periphery of the cylinder head 5a. 5b, it is not only troublesome to finish the seal on the ring embankment 5b, but also the weight of the cylinder body 5, which is held in a floating state, is biased and becomes heavy. Since it is necessary to form a thick ring bank 5b that has a function, the capacity of the suction chamber 16 is limited and becomes small.As a result, the pulmonary movement phenomenon on the suction side due to the refrigerant becomes large, and the suction chamber 16 becomes small. There are disadvantages such as reduced efficiency and increased noise due to the flow of refrigerant.
