Claims

[Claims for Utility Model Registration] (1) A valve cover is provided to cover a bearing that is attached to a cylinder of a compression section and rotatably supports a rotating shaft, and these bearings and the valve cover are used to connect a discharge port provided on the bearing. In a rotary compressor muffling device having a first muffling space for attenuating pressure pulsations of discharged gas, a muffling plate material is provided in the first muffling space to cover the discharge port of the bearing, and the bearing A muffler for a rotary compressor, characterized in that a second muffling space is formed between the muffler and the muffler plate, and a valve stopper portion of a discharge valve and a discharge port of the valve stopper portion are formed in the muffler plate. (2) The noise reduction device for a rotary compressor according to claim 1, wherein the second noise reduction space comprises one or more rooms. (3) At least one of the plurality of rooms of the first sound-muffling space and the second sound-muffling space is the second sound-muffling space.
communicates with the room containing the discharge port of the silencing space,
A muffler for a rotary compressor according to claim 1 or 2, which attenuates pressure pulsations of gas discharged from a discharge port in multiple stages. (4) The noise reduction of the rotary compressor according to claims 1 to 3 of the utility model registration claim, wherein a plurality of rooms in the second noise reduction space are provided with gas relief holes other than the discharge port of the valve stopper portion.
