Consequently, the temperature of the coolant on the thermostatic element is lower than that of the coolant returning from the engine, so that the actual switching point of the thermostatic valve may be at an undesirably high temperature

Embodiment Construction

[0030] Components that are identical or functionally identical to the components of the thermostatic valve 10 of FIG. 1 retain the reference numbers they have already introduced below.

[0031] image 3 A thermostatic valve 100 according to the invention is shown according to a first embodiment.

[0032] As in the elongated thermostatic valve 10 shown in FIG. 1 , the thermostatic element 20 delimiting the longitudinal axis A is substantially relative to the opposite engine-side and cooler-side coolant inlet 14 or 16 is aligned centrally, wherein the valve disk 22 is fixedly connected to the thermostatic element 20 .

[0033] The travel of the thermostatic element 20 takes place along a longitudinal axis A, which thus also defines the switching direction of the thermostatic valve 100 . The valve disk 22 is able to close and release the cooler-side coolant inlet 16 on a valve seat 24 . Furthermore, a second valve disk 26 is fixedly connected to the thermostatic element 20 , w...

Abstract

The present invention relates to a thermostatic valve for a cooling system of an internal combustion engine, the thermostatic valve comprising: a thermostat housing (12), the thermostat housing having a coolant inlet on the engine side and a cooler side, these coolant inlets are opposed to each other; Lateral coolant outlet to the internal combustion engine (18); And the valve disc (22), the valve disc having a valve seat with the cooler side of the coolant inlet (16) of the valve seat (24) in conjunction with the valve seat opposite the end face (37) and the valve disc is located in the cooler side of the coolant inlet and disposed between the thermostat element (20) in the thermostat housing, the thermostat element having a longitudinal axis that coincides with the switching direction of the valve disc (A), the valve disc having a disc portion (36) and a guiding element (30) connected to the disc portion on the outer edge of the disc portion, And the guide element has a steering surface on the outside (35), the thermostatic element is disposed on the longitudinal axis (A) and the valve disc is fixedly connected with the thermostat element.

Description

technical field [0001] The invention relates to a thermostatic valve for a cooling system of an internal combustion engine. Background technique [0002] Thermostatic valves are used to regulate the coolant temperature in the cooling circuit of internal combustion engines. Among the common cooling circuits are the so-called small cooling circuit and the large cooling circuit. In the "small cooling circuit", the coolant is directed through the engine but not through the cooler of the vehicle. In the "large cooling circuit", The coolant flows not only through the engine but also through the cooler, wherein the coolant again releases the heat absorbed by the engine in the cooler. In order to open and close the fluid connection between the individual subregions of the cooling circuit, the thermostatic valve has a temperature-sensitive thermostatic element which raises and lowers the valve disk which opens or closes the coolant inlet on the cooler side. [0003] FIG. 1 shows a ...
