Description

technical field [0001] The invention relates to the technical field of automobile engine cooling, in particular to a temperature-sensing integrated thermostat device used in an engine oil module. Background technique [0002] At present, many temperature-sensitive thermostats and bypass valves used in engine oil modules are two separate parts, which realize two functions of temperature regulation and pressure regulation respectively. When designing the oil module, the installation positions of the thermostat and the bypass valve are considered separately, resulting in complex design. Generally, the temperature sensing element of the thermostat is placed behind the piston of the thermostat. The temperature sensing element of the thermostat senses the oil cooled by the cooler, and the temperature difference between the oil entering the oil inlet will cause the thermostat to work. When the piston is opened frequently, it will oscillate. The traditional temperature-sensing the...
