Embodiment Construction
[0040] When the coolant temperature of the engine is high, the drive rod of the thermostat is heated and expanded, so that the valve of the thermostat is separated from the valve seat, and the opening formed by the separation of the valve and the valve seat is the inlet of the coolant into the large circulation channel. However, due to the limited distance between the valve and the valve seat when they are separated, the opening of the opening after the valve is separated from the valve seat is limited, which in turn makes the inlet area for the cooling liquid to flow into the large circulation channel small, resulting in inflow from the opening. The flow rate of coolant in the large circulation channel is large and the internal pressure drop of the thermostat is large, which will damage the service life and structural stability of the thermostat assembly.
[0041]In view of the above problems, the thermostat assembly provided by the embodiment of the present invention is provi...

The invention provides a thermostat assembly and an engine, which relate to the technical field of engines and are used to solve the problems of short service life and low structural stability of the thermostat assembly. The thermostat assembly includes a housing and a The thermostat inside the casing; the casing is provided with a sliding cavity, a small circulation channel and two large circulation channels; the thermostat includes a valve and a valve seat, the valve seat is fixedly installed in the opening of the sliding cavity, the valve is located inside the sliding cavity and It can slide inside the sliding chamber, and the side wall of the valve is provided with a first liquid outlet; when the valve is in the first position, the first liquid outlet is connected to a small circulation channel; when the valve is in the second position, the first liquid outlet One of the two large circulation passages is connected, and a second liquid outlet connected with the other of the two large circulation passages is formed between the valve and the valve seat. The thermostat assembly and the engine provided by the invention are used to improve the service life and structural stability of the thermostat assembly.
Description
technical field [0001] The invention relates to the technical field of engines, in particular to a thermostat assembly and an engine. Background technique [0002] The engine will generate a lot of heat during operation, resulting in a higher temperature of the engine casing. In order to reduce the temperature of the engine casing, cooling liquid is usually used to cool down the engine casing. However, as the working time of the engine increases, the temperature of the coolant also gradually increases. When the temperature of the coolant reaches a certain value, the coolant needs to be cooled by the radiator. When the coolant dissipates heat through the radiator, the cooling channel through which the coolant flows is called a large circulation channel; when the coolant does not dissipate heat through the radiator, the cooling channel through which the coolant flows is called a small circulation channel. [0003] In order to control the coolant, the coolant can flow in a la...
