The check valve and the muffler were considered to be completely separate parts, and the check valve was installed either in front of or behind the muffler. As shown in FIG. 1, in an example in which the check valve 2 is installed in front of the muffler 3, there is a problem in that the check valve 2 is damaged due to discharge pressure pulsations of the compressor 1. Also, the second
As shown in the figure, in the example in which the check valve 2 is installed behind the muffler 3, there is a problem in that the sound absorbing material of the muffler 3 is scattered. Furthermore, with this problem, when a pressure pulsation damping section was provided to prevent the sound absorbing material from scattering, the pressure loss of the fluid was large, resulting in a decrease in the overall performance of the compressor.

逆止弁付消音器が得られる。As shown in FIG. 4, the check valve 6 has a plurality of holes 11 and consists of a check valve seat 12, a valve guard 13, a valve plate 14, and the like. The present invention is composed of a pressure pulsation damping section 4, a muffler section 5, and a check valve 6, and the pressure pulsation damping section 4 is arranged on the fluid inlet side, the muffler section 5 is arranged on the outlet side, and therebetween A check valve 6 is arranged. First, the pressure pulsation of the fluid is attenuated by the pressure pulsation damping section 4 to a pulsation rate of about 5, which is enough to prevent damage to the check valve, and then the fluid flows into the check valve 6. and,
It passes through the check valve 6, but since the check valve 6 has a plurality of holes 11, the pressure pulsation is further attenuated, and the pulsation rate is about 2.
It reaches a level of 50 degrees and flows into the muffler section 5. As a result of actually measuring the pulsation rate in a screw compressor, when the pressure pulsation rate generated by the compressor is 15 degrees, the pulsation rate in the pressure pulsation damping section is 7 degrees, and the downstream of the check valve, that is, the muffler The pulsation rate was 2 at the entrance. After continuous operation, the check valve and silencer were inspected, but no damage was found. In addition, in order to prevent the sound absorbing material of the muffler from scattering, it is necessary to reduce the weight of the pressure pulsation vehicle to about 2, but if this is dealt with only by the pressure pulsation damping section without using a check valve, The pressure loss of this pressure pulsation damping section is approximately 0.2~/1-dG, and the pressure is 10oKW.
For a class of dry screw compressors, the overall performance is reduced by approximately 1. Therefore, the present invention provides a silencer with a check valve that is effective in preventing damage to the check valve due to fluid pressure pulsations and preventing the sound absorbing material of the silencer from scattering, and at the same time has low pressure loss resistance.

の飛散防止が可能となる。According to the present invention, since the check valve is provided between the pressure pulsation damping section and the muffler, damage to the check valve due to pressure pulsation of the fluid can be prevented, and the pressure pulsation damping effect of the check valve can be used to prevent damage to the check valve. , it becomes possible to prevent the sound absorbing material from scattering.
また、逆止弁の圧力脈動減衰効果を利用しているため、
流体の圧力損失抵抗も小さくできる。In addition, since it utilizes the pressure pulsation damping effect of the check valve,
Fluid pressure loss resistance can also be reduced.
