Claims

[Claims for Utility Model Registration] (1) A discharge valve for opening and closing a discharge hole is attached to a bearing section of a compression mechanism section of a rotary compressor main body, and a valve cover is attached around the bearing section, In this rotary compressor in which a silencing space is formed between the valve cover and the bearing section, the silencing space between the valve cover and the bearing section is provided with a silencing space surrounding the discharge valve. A rotary rotary, characterized in that a silencing member is provided in which a silencing space forming part that forms a second silencing space communicated with the silencing space is formed between the bearing part and the stopper of the discharge valve. type compressor. (2) The sound deadening member is formed by a pipe body with an open end on one end and a closed end on the other end, and the length of the passage of the pipe body is the length of the pipe between the valve cover and the bearing. Approximately 1 wavelength of pressure pulsations occurring within the space
4. The rotary compressor according to claim (1) of the utility model registration. (3) The rotary compressor according to claim (1) of the utility model registration, characterized in that the sound deadening member includes an integrally fixed part that is integrally fixed with the bearing part and the discharge valve. (4) The second sound deadening space is a combination of a recess formed in the bearing and a flat sound deadening member, or a flat plate of the bearing and a bulge forming the second sound deadening space. It is formed by either a combination of a sound deadening member, or a combination of a sound deadening member having a concave portion formed in the bearing portion and a bulge portion forming a second sound deadening space. A rotary compressor according to claim (1) of the utility model registration, characterized in that the rotary compressor is a rotary compressor according to claim (1).
