用于汽车排气系统的消声器

A silencer for car exhaust system

Abstract

The utility model provides a silencer for car exhaust system which includes casing, first baffle and second baffle, intake pipe and U -shaped pipe. Including lieing in in the casing expansion chamber between first, the second baffle. The intake pipe is equipped with the air inlet and extends and extension in the expansion chamber, be equipped with on the pipe wall of extension with a plurality of through -holes of expansion chamber intercommunication. The extension still be equipped with with port and part that the air inlet is relative are sealed half closure plate of port, wherein half closure plate semicircular in shape and shutoff are lived the latter half of port. The utility model discloses a set up half closure plate, when the exhaust of engine when the air inlet gets into the intake pipe, under of the stopping of half closure plate, partly exhaust is overflowed and is entered into the expansion chamber from the through -hole, another part is exhausted and is entered into the expansion chamber from the exhaust passage. So setting up, making the unlikely too much rising of mouth of pipe backpressure on the one hand, on the other hand also can effectively avoid the condensate return.
一种用于汽车排气系统的消声器,其包括壳体、第一挡板与第二挡板、进气管以及U形管。所述壳体内包括位于所述第一、第二挡板之间的膨胀腔。进气管设有进气口以及延伸入所述膨胀腔中的延伸部,所述延伸部的管壁上设有与所述膨胀腔连通的若干通孔。所述延伸部还设有与所述进气口相对的端口以及部分封闭所述端口的半堵板,其中所述半堵板呈半圆形且封堵住所述端口的下半部分。本实用新型通过设置半堵板,当发动机的排气自进气口进入进气管时,在半堵板的阻挡下,一部分排气自通孔溢出并进入到膨胀腔中,另一部分排气自排气通道进入到膨胀腔中。如此设置,一方面使得管口背压不致过多升高,另一方面也能有效避免冷凝水回流。
