Abstract

본 발명은 엔진의 냉각을 위해 냉각수의 온도를 검출하고 냉각수의 온도가 소정의 임계범위를 넘어서는 경우에 이를 다시 냉각할 수 있도록 제어하는 수온조절기의 고장시 엔진과열 상태를 방지하기 위한 장치에 관한 것으로, 엔진(2)을 통한 후 출력되는 냉각수의 온도를 검출하기 위한 온도센서(5)와, 냉각수의 순환시에 순환로에서의 냉각수 압력을 검출하는 압력센서(4)와 도시하지는 않았지만 상기 온도센서(5)와 압력센서(4)에서 출력되는 감지신호를 입력받아 제어신호를 출력하는 제어부와, 상기 제어부의 제어신호에 따라 냉각수의 순환로중 바이패스 통로를 개폐동작하는 밸브(6)등으로 구성되어 수온조절기의 고장시 엔진이 과열되어 소손될 수 있다는 종래의 문제점을 해소하는 효과가 있다.The present invention relates to an apparatus for preventing an engine overheating condition in the event of a water temperature controller that detects the temperature of the cooling water for cooling the engine and controls the cooling water to be cooled again when the temperature of the cooling water exceeds a predetermined threshold range. And a temperature sensor 5 for detecting the temperature of the coolant output through the engine 2 and a pressure sensor 4 for detecting the coolant pressure in the circulation path at the time of circulation of the coolant and the temperature sensor (not shown). 5) and a control unit for receiving a detection signal output from the pressure sensor 4 and outputting a control signal, and a valve 6 for opening and closing the bypass passage of the circulation path of the coolant according to the control signal of the control unit. When the water temperature regulator breaks down, there is an effect of solving the conventional problem that the engine may be overheated and burned out.
