Embodiment Construction

[0017] Such as figure 1 , 2 As shown, the electric heating element 7, the wire 10, and the tail handle 9 are injected together to form the electric heating element assembly. Then, the electric heating element assembly is pre-embedded in the body 5, and the electric heating element assembly and the body The junction of 5 is sealed with a graphite sealing gasket 8 to ensure the tightness of the product. Then the wax pill 6, the rubber hose 4, the sealing ring 3, the gland 2, and the push rod 1 are sequentially assembled into the body 5, and the parts are fixed together by the riveting process. The wire 10 is drawn out from the tail handle at the bottom of the induction body assembly 14, passes through the wire cavity that is integrated with the cavity, and is connected to the insert on the socket assembly 11 that is connected to the outside of the cavity assembly 12; the tail handle 9 and the wire cavity are sealed by a rubber sealing washer 8, and the socket assembly is conne...

Abstract

The invention provides an electronic thermostat, consisting of an inductor assembly, a valve, a cavity assemble and a socket assembly. The inductor assembly comprises a push rod, a press cover, a sealing ring, a rubber hose, a body and a wax pill, and is provided with an electric heating element assembly. The electric heating element assembly comprises an electric heating element, a conducting wire and a tail handle; the electric heating element is positioned in a wax pill cavity; the tail handle is exposed outside the body; the conducting wire of the electric heating element is led out from the tail handle; the tail handle, the conducting wire and the electric heating element are injection-molded and connected into a whole; and the joint of the electric heating element and the body is provided with a sealing washer as well. After the conducting wire is led out from the tail handle, the conducting wire is connected with an insert sheet connected with the socket assembly outside a cavity. The electronic thermostat has the advantages that the thermostat can reduce oil consumption and the emission of CO, HC and smoke dust, and can control the emission of nitrogen-oxygen compounds.

Description

technical field [0001] The invention relates to an internal combustion engine, in particular to a thermostat for a water cooling system of an internal combustion engine. Background technique [0002] At present, ordinary wax-type thermostats work passively, that is, when the temperature of the engine rises, the temperature-sensing wax expands, compresses the hose, and then pushes the push rod to move. The cooling water in the large circulation circuit of the engine flows to the radiator, and the engine starts to dissipate heat. When the engine temperature continues to rise, the valve is also continuously opened, the flow of cooling water flowing through the radiator (big cycle) is also continuously increased, and the heat dissipation of the engine is also continuously strengthened. As the engine temperature drops, the induction body assembly begins to fall back under the action of the main spring, the valve begins to close, the flow rate of the cooling water in the large ci...
