[0058] figure 1 A schematic diagram of a temperature control valve provided by an embodiment of the present invention; figure 2 A specific structural schematic diagram of a temperature control valve provided by an embodiment of the present invention; image 3 An explosion diagram of a temperature control valve provided in an embodiment of the present invention; Figure 4 for figure 1 Sectional view along the A-A direction; Figure 5 A schematic diagram of a temperature control valve in a low-temperature oil circuit state provided by an embodiment of the present invention; Figure 6 It is a schematic diagram of a temperature control valve in a high-temperature oil circuit state provided by an embodiment of the present invention. Such as Figure 1-Figure 6 As shown, the temperature control valve 1 provided in this embodiment includes a housing 10, a valve body 20 and a thermostat 30, the housing 10 is covered on the valve body 20, the valve body 20 has a housing chamber 24, ...

[0084] When the first spool 32 is in the initial state, the third through-hole 23 and the first through-hole 21 are kept closed, at this time, all the low-temperature engine oil entering through the first through-hole 21 flows into the second through-hole 22, that is, the low-temperature All the engine oil enters into the second receiving chamber 242 for circulation. At this time, the system flow resistance in the second receiving chamber is too large, which may cause the thermostat 30 to fail to open normally, thereby affecting the normal operation of the temperature control system of the engine. In order to reduce the system flow resistance in the second accommodating chamber when the oil circuit is at low temperature, the diameter of the third through hole 23 is larger than the width of the first valve core 32 so that the third through hole 23 communicates with the second accommodating chamber 242 .
[0085] Wherein, when the diameter of the third through hole 23 is greater ...

[0090] When the oil carried in the oil pump carries too many impurities, the oil cooler may be blocked. At this time, the oil pump has serious internal leakage due to excessive back pressure, and the volumetric efficiency is greatly reduced, thereby reducing the oil flow. When the oil flow rate is reduced, the pressure cannot be built up normally, and it is easy to cause serious failures such as cylinder scuffing and tile melting. Figure 7 Another schematic diagram of the temperature control valve in the high-temperature oil circuit state provided for the embodiment of the present invention, as shown in Figure 7 As shown, optionally, the thermostat 30 also includes a second valve core 34, a fixed sleeve 35 and a first elastic member 36, the second valve core 34 and the first elastic member 36 are located in the fixed sleeve 35, and the first elastic member 36 abuts between the bottom of the fixing sleeve 35 and the second valve core 34, the opening end of the fixing sleeve 3...
