とができる。 In such a configuration, a discharge passage 15 passing through the axis of the cylinder shaft 12 is provided in the cylinder shaft 12, and an outlet hole 16 is also provided at the center of the silencing chamber 17 in a corresponding manner. Therefore, when sound is emitted from the exit hole 16, the sound deadening chamber 1
7 The sound reflected from the inner wall surface and the direct sound radiated from the exit hole 16 cause phase interference with each other, and the noise inside the muffling chamber 17 can be reduced. If it is located at the center and installed at the center of the vertical cross section, the space near the exit hole 16 is located at the node of a standing wave that may occur in the space inside the silencing chamber 17, so the silencing When noise is radiated from nodes of standing waves within the room 17, the noise forms a sound field that is difficult to swallow. Therefore, it is possible to prevent the occurrence of standing noise in the cross-sectional circumferential direction that occurs in the interior of the silencing chamber 17, and furthermore, since the outlet hole 16 is disposed at the center of the height of the silencing chamber 17. , it is possible to prevent the occurrence of resonance in the height direction that occurs in the inner chamber of the silencing chamber 17, and because the discharge passage 15 is provided in the cylinder shaft 12 and the silencing chamber 17 is provided in the upper bearing 5, the size is reduced. The structure can be easily configured and the assembly can be simplified. Moreover, since the compressed fluid is led out from the muffling chamber 17 through the discharge pipe 18 without leaking into the closed container 1, a decrease in compression efficiency can be suppressed.
