Abstract

본원 발명의 목적은 공냉식 엔진의 인터쿨러와 바이패스 관로의 개폐절환 작동구조를 단순화시킨 인터쿨러의 바이패스 장치를 제공하는데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a bypass device for an intercooler that simplifies the opening and closing operation structure of an intercooler and a bypass pipe of an air-cooled engine.

상기한 목적을 달성하기 위한 본 발명의 수단은 엔진 냉각에 사용된 더워진 공기를 냉각시키는 인터쿨러와, 엔진의 과냉시 상기 인터쿨러를 우회하여 공기를 순환시키는 바이패스 관로와, 상기 인터쿨러 관로와 바이패스 관로를 공기온도조건에 따라 선택적으로 개폐하는 밸브와를 포함하여 구성되는 엔진 냉각장치에 있어서, 인터쿨러 관로를 개폐하는 상부밸브와 바이패스 관로를 개폐하는 하부밸브가 단일체로 형성된 H자형밸브와; 상기 H자형밸브의 하부밸브에 일단이 고정된 피스톤과; 상기 피스톤을 수용하며 상기 피스톤과의 사이에 형성되는 공간에 공기 온도에 따라 팽창 또는 수축하는 왁스를 내장하는 실린더와; 상기 왁스의 팽창력에 대항하여 상기 피스톤을 탄발지지하는 리턴스프링과; 로 구성되어 있음을 특징으로 한다.Means of the present invention for achieving the above object is an intercooler for cooling the warm air used for engine cooling, a bypass pipe for circulating the air by bypassing the intercooler when the engine is overcooled, and the intercooler pipe and the bypass An engine cooling apparatus comprising a valve for selectively opening and closing a pipeline according to air temperature conditions, the engine cooling apparatus comprising: an H-shaped valve having an upper valve for opening and closing an intercooler passage and a lower valve for opening and closing a bypass passage; A piston having one end fixed to the lower valve of the H-shaped valve; A cylinder accommodating the piston and accommodating a wax that expands or contracts according to air temperature in a space formed between the piston; A return spring for elastically supporting the piston against the expansion force of the wax; It is characterized by consisting of.
