<p>PURPOSE:To increase rigidity in each condition before change in a volume and after the change, largely improve silencing effect as a silencer for subject of liquid, and set moving operation of movable parts for changing the volume also to be sufficiently applicable to the case of high pressure liquid for improving work efficiency further for a volume-changeable resonance type silencer. CONSTITUTION:A silencer is formed of a neck part 1 connected to a main pipe A at one end, and an expansion volume part 2 connected to the other end of the neck part 1, the expansion volume part 2 is formed of a fixed cylinder 3 connected to the neck part 1, and a movable cylinder 4 movable on the guide of its circumferential surface, the movable cylinder is provided with a clamp device 190 around it, and a pressure receiving surface 30 for balancing is provided at its outer circumferential part.</p> |
