Abstract

본 발명은 자동차용 머플러에 관한 것으로, 특히 자동차의 주행속도 또는 엔진의 회전속도에 따른 배기압의 고저에 따라 배기저항이 적절히 가감됨으로써 최적의 배기효율을 얻을 수 있도록 한 배기압 감응형 자동차용 머플러에 관한 것이다. 본 발명에 의한 머플러는, 배기압이 낮을 때 배기저항치를 증가시키고 배기압이 높을 때 배기저항치를 감소시키기 위한 수단을 구비하여 구성된다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a muffler for automobiles, and in particular, an exhaust pressure sensitive automobile muffler which can obtain an optimum exhaust efficiency by suitably reducing exhaust resistance according to the height of exhaust pressure according to the running speed of an automobile or the rotational speed of an engine. It is about. The muffler according to the present invention comprises a means for increasing the exhaust resistance value when the exhaust pressure is low and reducing the exhaust resistance value when the exhaust pressure is high.
