本发明装置的具体工作原理为:The specific working principle of the device of the present invention is:

通常状态下,活塞处于打开状态,即通过进油入口通入的机油温度低于设定值时,活塞在可伸缩限位件的作用下不封闭机油流通口,进入壳体腔室的机油能够经过滤芯入口通入滤芯;部分机油可以进入冷却器,进入滤芯入口和冷却器的机油流量视机油从进油入口的流量而定。Under normal conditions, the piston is in the open state, that is, when the temperature of the oil introduced through the oil inlet is lower than the set value, the piston does not close the oil flow port under the action of the retractable stopper, and the oil entering the housing chamber can pass through. The inlet of the filter element leads to the filter element; part of the oil can enter the cooler, and the oil flow into the filter element inlet and the cooler depends on the flow rate of the oil from the oil inlet.

当进油入口通入高温机油时(机油温度高于设定值时),温度感应元件因升温而膨胀推动活塞运动,活塞封闭进油入口,此时,高温机油无法从进油腔室进入出油腔室,即高温机油需进入冷却器入口,机油经冷却器降温到一定温度后到达各润滑点,确保润滑点润滑效果,且延长机油寿命。When the high temperature oil is introduced into the oil inlet (when the oil temperature is higher than the set value), the temperature sensing element expands due to the temperature rise and pushes the piston to move, and the piston closes the oil inlet. At this time, the high temperature oil cannot enter and exit from the oil inlet chamber. The oil chamber, that is, the high-temperature oil needs to enter the inlet of the cooler. The oil is cooled to a certain temperature by the cooler and then reaches each lubrication point to ensure the lubrication effect of the lubrication point and prolong the life of the oil.

当进油腔室通入高温机油,活塞封闭机油流通口,此时滤芯入口处于关闭状态,如果在某些极限工况下,比如冷却器支路出现故障(如阻塞),此时若没有机油进入滤芯,会导致发动机没有机油可使用,这种情况应当予以避免。本装置中的旁通阀组件发挥作用,即如果一旦出现这种状况,当进油入口与润滑端压差上升到设定开启压力时,进油腔室的高压机油作用在旁通阀片上,旁通阀片移动,活塞上的旁通通孔打开,机油通过,进入滤芯入口,这样就避免上述问题,使发动机润滑系统中保持有机油通入,使发动机运行中各个需要润滑的部件得到保护。When the oil inlet chamber is fed with high-temperature oil, the piston closes the oil flow port, and the filter element inlet is closed. Into the filter element, the engine will have no oil to use, this situation should be avoided. The bypass valve assembly in this device works, that is, if this situation occurs, when the pressure difference between the oil inlet and the lubricating end rises to the set opening pressure, the high-pressure oil in the oil inlet chamber acts on the bypass valve plate. The bypass valve plate moves, the bypass hole on the piston opens, and the oil passes through and enters the filter element inlet, so as to avoid the above problems, keep the oil in the engine lubrication system, and protect the parts that need to be lubricated during engine operation.

与现有技术相比,本发明具有以下优点:Compared with the prior art, the present invention has the following advantages:

1、与专利CN211422724U公开的用于机油模块中的感温式集成节温器装置采用一体式支架结构相比,本发明集成节温器装置去除了支架,节省空间,增大了旁通阀截面积减小了流阻。1. Compared with the integrated bracket structure used in the temperature-sensing integrated thermostat device used in the oil module disclosed in the patent CN211422724U, the integrated thermostat device of the present invention removes the bracket, saves space, and increases the bypass valve cutoff.

本发明装置的具体工作原理为:The specific working principle of the device of the present invention is:

如图2,通常状态下,活塞2处于打开状态,即通过进油入口8通入的机油温度低于设定值时,活塞2在可伸缩限位件的作用下不封闭机油流通口,进入壳体1腔室的机油能够经过滤芯入口9通入滤芯;部分机油可以进入冷却器,进入滤芯入口9和冷却器的机油流量视机油从进油入口8的流量而定。As shown in Fig. 2, in the normal state, the piston 2 is in the open state, that is, when the temperature of the oil introduced through the oil inlet 8 is lower than the set value, the piston 2 does not close the oil flow port under the action of the retractable limiter, and enters the The oil in the chamber of the housing 1 can pass into the filter element through the filter element inlet 9; part of the oil can enter the cooler, and the oil flow into the filter element inlet 9 and the cooler depends on the oil flow from the oil inlet 8.

如图3,当进油入口8通入高温机油时(机油温度高于设定值时),温度感应元件3因升温而膨胀,在顶杆301的作用下推动活塞2运动,活塞2封闭进油入口8,此时,高温机油无法从进油腔室进入出油腔室,即阻止高温机油经滤芯入口9进入滤芯,确保润滑点润滑效果,且延长机油寿命。As shown in Fig. 3, when the oil inlet 8 is fed with high-temperature oil (when the oil temperature is higher than the set value), the temperature sensing element 3 expands due to the temperature rise, and pushes the piston 2 to move under the action of the ejector rod 301, and the piston 2 closes the inlet.
