To provide an energy absorbing and silencing device, exhibiting uniform energy absorbing and silencing effect in a flow control valve and installed within the length of an existing pipeline.

In this energy absorbing and silencing device for restraining noise, vibration and so on due to energy absorption of a valve throttle mechanism in the pipeline flow, in order to obtain the pipeline loss water head corresponding to the energy absorption amount of the valve throttle mechanism, a collecting passage 17 composed of a number of fine passages having a cross area remarkably smaller than the cross area of the pipeline 15 is disposed on the upstream side or on the downstream side of the valve body 11, and a very small gap is kept between the valve element and the collecting passage 17 not to generate resistance due to sliding friction.
