摘要： One aspect of the present disclosure provides a muffler including an exhaust pipe and a space forming member. The exhaust pipe has a cylindrical shape having a flow passage inside through which exhaust gas passes. The space forming member forms closed spaces between itself and the exhaust pipe, the closed spaces being branched from the flow passage and adjacent to the flow passage. Each of the closed spaces and the flow passage communicate with one another via a single communication hole.

摘要： A muffler comprises an outer shell, an outlet pipe, and a restraining mechanism. A restraining mechanism restrains a height of spout of a liquid that flows inside the outlet pipe through a designated vent hole, the designated vent hole is at least one vent hole facing against a bottom surface of the outer shell among the at least one vent hole that the outlet pipe comprises.

摘要： The present disclosure provides a muffler system that can effectively reduce exhaust noises. The muffler system includes an exhaust passage and a first muffler. The exhaust passage is configured to allow a flow of an exhaust gas. The first muffler is an expansion chamber muffler and disposed in the exhaust passage. The first muffler is situated upstream of a first position in a flow direction of the exhaust gas. The first position is located away from an upstream end of the exhaust passage by one third of an entire length of the exhaust passage.

摘要： A silencer comprises a casing, an inlet pipe for introducing an exhaust into the casing, and an outlet pipe for discharging the exhaust out of the casing. A lid is provided at an exhaust inflow side opening of the outlet pipe and arranged to close the exhaust inflow side opening. The lid has an exhaust inlet for flowing the exhaust into the outlet pipe, a valve body for opening and closing the exhaust inlet, and at least one communication hole formed separately from the exhaust inlet. The valve body is configured to be rotationally movable about a rotation axis of the valve body inside the outlet pipe. The at least one communication hole is provided closer to the rotation axis of the valve body than the exhaust inlet.

摘要： Provided is a muffler comprising: an outer shell; an outlet pipe, which is formed into a tubular shape containing a pair of open end-parts and is comprising an inlet port, wherein one of the open end-parts and the inlet port are arranged inside the outer shell; a valve body formed into a plate-like shape to cover the inlet port from the inside of the outlet pipe; an axis member that pivotally supports the valve body to the outlet pipe so that the valve body pivots inside the outlet pipe; and a biasing member that applies a biasing force in the radial direction of the outlet pipe to the valve body so as to occlude the inlet port.
