吸音型消音器。[Scope of Claim for Utility Model Registration] (1) In a silencer for a vehicle exhaust system in which an exhaust pipe having a large number of small holes is passed through an outer cylinder filled with a sound-absorbing material, A straight branch pipe having a large number of small holes is connected to the peripheral wall of the insertion part in the outer cylinder, and on the inlet side of the branch pipe,
A sound absorbing muffler characterized by being provided with an on-off valve that opens an exhaust gas flow path of a branch pipe in response to an increase in engine speed. (2) A utility model registration request characterized in that a plurality of branch pipes are connected to the exhaust pipe, and the opening/closing valve provided in each branch pipe sequentially opens the exhaust gas flow path in response to an increase in engine speed. A sound-absorbing muffler according to scope 1. (3) A utility model characterized in that a plurality of branch pipes are connected to the exhaust pipe, and the on-off valve provided in each branch pipe simultaneously opens the exhaust gas flow path when the engine speed exceeds a predetermined value. A sound absorbing muffler according to claim 1.
