[0002] This disclosure generally relates to the field of engine coolant systems. Background Technology
[0003] In an internal combustion engine system, the engine coolant system delivers coolant from the reservoir to the engine to transfer heat from the engine to the coolant. This engine coolant system selectively distributes the coolant output from the engine between the radiator and the radiator bypass, thereby altering the amount of heat dissipated by the coolant and thus controlling its temperature. Summary of the Invention
[0004] Various embodiments provide a thermostat housing assembly. The thermostat housing assembly includes a thermostat housing and a valve assembly. The thermostat housing includes: an inlet portion having a first port; a radiator outlet portion having a second port; a radiator bypass outlet portion having a third port; and a housing divider portion. The housing divider portion defines: a first orifice providing selective fluid-providing communication from the first port to the third port; and a second orifice providing fluid-providing communication from the first port to the third port. The valve assembly is adjustable between a first configuration and a second configuration, the first configuration selectively blocking fluid-providing communication from the first port to the second port, and the second configuration selectively blocking fluid-providing communication from the first port to the third port through the first orifice. When the valve assembly is in the second configuration, the third port provides fluid communication with the first port through the second orifice.
[0005] In some embodiments, the first aperture has a first flow area, which is larger than the second flow area of the second aperture.
[0006] In some embodiments, the first axis of the first port is substantially perpendicular to the second axis of the second hole.
[0007] In some embodiments, the first axis of the first port is substantially parallel to the second axis of the first hole.
[0008] In some embodiments, the first axis of the second hole is offset from the second axis of the third port in a direction substantially perpendicular to the first axis.
[0009] In some embodiments, the first axis of the second hole is offset toward the second axis of the third port from the first port.
[0010] In some embodiments, the first axis of the second hole intersects with the flow area of the third port.

The radiator assembly is in fluid communication with the downstream component. The radiator bypass pipe is in fluid communication with the downstream component and is connected in parallel with the radiator assembly. The thermostat housing assembly includes a thermostat housing and a valve assembly. The thermostat housing defines: a cavity in fluid receiving communication with the engine and selectively in fluid communication with the radiator assembly and the radiator bypass pipe; a first orifice providing selective fluid communication from the cavity to the radiator bypass pipe; and a second orifice providing fluid communication from the cavity to the radiator bypass pipe. The valve assembly is adjustable between a first configuration and a second configuration. The first configuration selectively blocks fluid communication from the cavity to the radiator assembly, and the second configuration selectively blocks fluid communication from the cavity to the radiator bypass pipe through the first orifice. When the valve assembly is in the second configuration, the cavity is in fluid communication with the radiator bypass pipe through the second orifice.
[0016] In some embodiments, the downstream component is selected from the group consisting of: a pump configured to drive coolant flow through a coolant system; an oil cooler module configured to remove heat from oil flowing through the engine system; and a coolant module configured to supply coolant to the engine through the coolant system.
[0017] Various other embodiments provide a method of operating a thermostat housing assembly. The method includes: operating a valve assembly in a first configuration, adjusting the valve assembly from the first configuration to a second configuration, and operating the valve assembly in the second configuration. The first configuration selectively blocks fluid communication from a cavity of the thermostat housing assembly to a radiator assembly. The second configuration selectively blocks fluid communication from the cavity to a radiator bypass pipe through a first orifice of the thermostat housing assembly, and allows fluid communication from the cavity to the radiator bypass pipe through a second orifice of the thermostat housing assembly.
[0018] In some embodiments, operating the valve assembly in a first configuration allows fluid to be communicated from the cavity to the radiator bypass pipe through a first orifice and a second orifice.
[0019] In some embodiments, operating the valve assembly in a second configuration allows fluid communication from the cavity to the radiator assembly.
[0020] In some embodiments, in response to the coolant in the thermostat housing assembly falling below a first temperature threshold, the valve assembly operates in a first configuration, and further in response to the coolant in the thermostat housing assembly falling below the first temperature threshold, the auxiliary valve assembly operates in a third configuration to selectively block fluid communication from the cavity to the radiator assembly.

[0022] In some embodiments, in response to the coolant in the thermostat housing assembly being higher than a second temperature threshold, the valve assembly operates in a second configuration, where the second temperature threshold is greater than a first temperature threshold.
[0023] In some embodiments, when the valve assembly is in a first configuration and a second configuration, fluid communication is allowed from the cavity to downstream components via a radiator bypass pipe.
[0024] These and other features, together with their structure and operation, will become clear in the detailed description below in conjunction with the accompanying drawings, wherein the same elements are referred to by the same reference numerals in the drawings described below.

[0033] The embodiments described herein generally relate to a coolant system and / or components thereof. More specifically, the embodiments described herein relate to a coolant system including a thermostat housing assembly.
[0034] According to various implementation schemes, the thermostat housing assembly enables the coolant system to prevent the flow rate and / or pressure of the coolant flow delivered from the thermostat housing assembly to the radiator assembly from exceeding the maximum flow rate threshold and / or maximum pressure threshold of the radiator assembly.
[0035] In some embodiments, the coolant system is configured to direct coolant to the engine to remove heat from the engine. In some embodiments, the engine is an internal combustion engine that consumes fuel to produce mechanical power. In some embodiments, the engine is one of a diesel engine, a gasoline engine, a hydrogen engine, or a natural gas engine.
[0036] In one example embodiment, the thermostat housing assembly is configured to direct coolant flow received from the engine between the radiator assembly and the radiator bypass pipe. The thermostat housing assembly includes a thermostat housing and a valve assembly. The thermostat housing defines: a cavity in communication with the engine fluid receiving system; a first orifice providing selective fluid communication from the cavity to the radiator bypass pipe; and a second orifice providing fluid communication from the cavity to the radiator bypass pipe. The valve assembly is adjustable between a first configuration that selectively blocks fluid communication from the cavity to the radiator assembly, and a second configuration that selectively blocks fluid communication from the cavity to the radiator bypass pipe through the first orifice. When the valve assembly is in the second configuration, the cavity is in fluid communication with the radiator bypass pipe through the second orifice; therefore, regardless of the valve assembly configuration, the thermostat housing assembly delivers a portion of the coolant flow to the radiator bypass pipe.
[0037] Before turning to the accompanying drawings, this document describes various embodiments of a coolant system, a thermostat housing assembly, and its components. It should be understood that while individual components are described in detail, these details should be considered as examples only. Furthermore, these details may include variations described herein. Therefore, it should be understood that although individual components may be described with respect to one embodiment, unless otherwise stated, any component may be used in any other embodiment described herein.
[0038] refer to Figure 1The diagram illustrates a block diagram of an engine system 100 according to an example embodiment. The engine system 100 includes an engine 102. The engine 102 includes a coolant inlet portion 106 and a coolant outlet portion 108. The engine system 100 also includes a coolant system 110 fluidly coupled to the engine 102. The coolant system 110 is configured to direct at least a portion of the coolant in the engine system 100 from the coolant outlet portion 108 to the coolant inlet portion 106.
[0039] exist Figure 1 In this configuration, engine system 100 is included in the vehicle. The vehicle can be any type of on-road or off-road vehicle, including but not limited to wheel loaders, forklifts, long-haul trucks, medium-duty trucks (e.g., pickup trucks), passenger cars, two-door sports cars, and any other type of vehicle. In other embodiments, engine system 100 may be embodied in stationary equipment, such as a generator or generator set. All these variations are intended to fall within the scope of this disclosure.
[0040] exist Figure 1 In the configuration shown, engine 102 is an internal combustion engine (ICE). The internal combustion engine burns fuels such as diesel, gasoline, hydrogen, natural gas, etc., to generate power. In some embodiments, engine 102 may be part of a hybrid power system having a combination of an internal combustion engine and at least one electric motor coupled to at least one battery. In some embodiments, engine system 100 may be configured as a mild hybrid system, a parallel hybrid system, a series hybrid system, or a series-parallel power system.
[0041] Engine 102 includes one or more cylinders 104 (e.g., combustion cylinders). The cylinder 104 is located within the combustion chamber of engine 102. Figure 1 As shown, engine 102 includes six cylinders 104. However, it should be understood that engine 102 may include more than... Figure 1 The engine 102 may have more or fewer cylinders 104 (e.g., at least one). Furthermore, the cylinders 104 may be arranged in any suitable manner (e.g., inline, horizontal, V-type, or other suitable cylinder arrangement). The coolant received by the engine 102 from the coolant system 110 can remove some of the heat generated by the cylinders 104 when fuel is burned in them to produce power, thereby keeping the temperature of the engine 102 below a temperature threshold.
[0042] The coolant system 110 includes a thermostat housing assembly 200. The thermostat housing assembly 200 is configured to direct an outlet coolant flow from the engine 102 to one or more downstream components. A coolant outlet portion 108 of the engine 102 is in fluid communication with the thermostat housing assembly 200. For example, the thermostat housing assembly 200 may be configured to direct a coolant flow from the engine 102 to at least a downstream component 140. The following will be combined with… Figures 2 to 8 A more detailed description of the thermostat housing assembly 200 is provided below.
[0043] Coolant system 110 includes radiator assembly 130. Radiator assembly 130 is configured to dissipate heat from coolant flowing through it, thereby reducing coolant temperature. For example, when coolant temperature is above a coolant temperature threshold, coolant flowing through coolant system 110 may be directed to radiator assembly 130 to reduce coolant temperature below the coolant temperature threshold. As another example, radiator assembly 130 may include a heat exchanger configured to reduce the temperature of coolant flow through it. Thermostat housing assembly 200 selectively provides fluid communication with radiator assembly 130. For example, thermostat housing assembly 200 may be positioned in a first configuration that selectively blocks fluid communication from thermostat housing assembly 200 to radiator assembly 130, and a second configuration that selectively allows fluid communication from thermostat housing assembly 200 to radiator assembly 130.
[0044] The coolant system 110 includes a radiator bypass pipe 132. The radiator bypass pipe 132 is arranged in parallel with the radiator assembly 130. For example, when the coolant temperature is below a coolant temperature threshold, the coolant flowing through the coolant system 110 can be directed to the radiator bypass pipe 132, so that the coolant does not flow through the radiator assembly 130 and the coolant temperature does not decrease.
[0045] In various embodiments, portions of the thermostat housing assembly 200 are selectively fluid-supplied in communication with the radiator bypass pipe 132. For example, in some embodiments, the thermostat housing assembly 200 may be positioned in a first configuration that selectively allows fluid communication with the radiator bypass pipe 132 via a first orifice 242, and a second configuration that selectively blocks fluid communication with the radiator bypass pipe 132 via the first orifice 242.
[0046] Coolant system 110 includes downstream component 140 (e.g., downstream device, etc.). Radiator assembly 130 and radiator bypass pipe 132 are in fluid communication with downstream component 140. Downstream component 140 can be any suitable component located downstream of radiator assembly 130 and radiator bypass pipe 132. For example, downstream component can be a pump that drives coolant flow through coolant system 110, an oil cooler module that removes some heat from engine oil flowing through engine system 100, or a coolant module that supplies coolant flowing through coolant system 110 to coolant inlet portion 106 of engine 102. Downstream component 140 is in fluid communication with engine 102. For example, downstream component 140 may be in fluid communication with coolant inlet portion 106 of engine 102.
[0047] In the example arrangement, engine 102 receives an intake coolant stream. As described above, engine 102 burns fuel to generate power. The coolant in the intake coolant stream carries away some of the heat generated by engine 102. Thermostat housing assembly 200 receives the coolant stream from engine 102, which includes some of the heat generated by engine 102 that has been carried away by the coolant. Thermostat housing assembly 200 directs the coolant stream through radiator assembly 130 and / or through radiator bypass pipe 132 to downstream component 140. Downstream component 140 returns the coolant to engine 102 as an intake coolant stream.
[0048] The thermostat housing assembly 200 is shown together with other components of the engine system 100 (e.g., engine 102 and its components) and other components of the coolant system 110 (e.g., radiator assembly 130, radiator bypass pipe 132, downstream component 140, etc.). It should be understood that the components shown in dashed lines in the engine system 100 are shown only as examples. Therefore, some embodiments described herein relate only to the thermostat housing assembly 200. Other embodiments described herein include the thermostat housing assembly 200 and one or more other components of the engine system 100, such as engine 102, downstream component 140, radiator assembly 130, and / or radiator bypass pipe 132. For example, in these embodiments, the thermostat housing assembly 200 is in fluid receiving communication with engine 102, fluidly provided communication with radiator bypass pipe 132, and selectively fluidly provided communication with radiator assembly 130.
[0049] The thermostat housing assembly 200 includes a thermostat housing 210 and a valve assembly 260. The thermostat housing 210 includes an inlet portion 214, a radiator outlet portion 216, a radiator bypass outlet portion 218, and a housing partition portion 240. The inlet portion 214 has a first port 220. The radiator outlet portion 216 has a second port 222. The radiator bypass outlet portion 218 has a third port 224. The housing partition portion 240 defines: a first orifice 242 that provides selective fluid communication from the first port 220 to the third port 224; and a second orifice 244 that provides fluid communication from the first port 220 to the third port 224. The valve assembly 260 is adjustable between a first configuration that selectively blocks fluid communication from the first port 220 to the second port 222, and a second configuration that selectively blocks fluid communication from the first port 220 through the first orifice 242 to the third port 224. When the valve assembly 260 is in the second configuration, the third port 224 is fluidly connected to the first port 220 through the second hole 244.
[0050] Engine system 100 includes: an engine 102; a downstream component 140 in fluid communication with the engine; a radiator assembly 130 located between the engine 102 and the downstream component 140; a radiator bypass pipe 132 located between the engine 102 and the downstream component 140; and a thermostat housing assembly 200. Radiator assembly 130 is in fluid communication with downstream component 140. Radiator bypass pipe 132 is in fluid communication with downstream component 140 and is connected in parallel with radiator assembly 130. Thermostat housing assembly 200 includes a thermostat housing 210 and a valve assembly 260. The thermostat housing 210 defines: a cavity 212 in fluid receiving communication with the engine 102 and selectively fluid-providing communication with the radiator assembly 130 and the radiator bypass pipe 132; a first orifice 242 providing selective fluid communication from the cavity 212 to the radiator bypass pipe 132; and a second orifice 244 providing fluid communication from the cavity 212 to the radiator bypass pipe 132. A valve assembly 260 is adjustable between a first configuration that selectively blocks fluid communication from the cavity 212 to the radiator assembly 130, and a second configuration that selectively blocks fluid communication from the cavity 212 to the radiator bypass pipe 132 through the first orifice 242. When the valve assembly 260 is in the second configuration, the cavity 212 is fluidly connected to the radiator bypass pipe 132 through the second orifice 244.
[0051] A method 300 of operating the thermostat housing assembly 200 includes: operating the valve assembly 260 in a first configuration, adjusting the valve assembly 260 from the first configuration to a second configuration, and operating the valve assembly 260 in the second configuration. The first configuration of the valve assembly 260 selectively blocks fluid communication from the cavity 212 of the thermostat housing assembly 200 to the radiator assembly 130. The second configuration of the valve assembly 260 selectively blocks fluid communication from the cavity 212 to the radiator bypass pipe 132 through a first orifice 242 of the thermostat housing assembly 200, and allows fluid communication from the cavity 212 to the radiator bypass pipe 132 through a second orifice 244 of the thermostat housing assembly 200.
[0052] In some embodiments, the coolant system 110 includes a downstream component 140, a radiator assembly 130, a radiator bypass pipe 132, and a thermostat housing assembly 200. The downstream component 140 can be any suitable component located downstream of the radiator assembly 130 and the radiator bypass pipe 132. For example, the downstream component 140 can be any component of the coolant system 110 located between (a) the radiator assembly 130 and the radiator bypass pipe 132 and (b) the engine 102. In some embodiments, the downstream component 140 is a pump, an oil cooler module, or a coolant module.
[0053] As described above, in some embodiments, one or more of the engine 102, radiator assembly 130, radiator bypass pipe 132 and downstream component 140 may not be included in the provided system; that is, the system or subsystem may be configured to include fewer components than all the components of the engine system 100.
[0054] The flow path of the coolant flow (e.g., coolant fluid flow or a portion thereof) through the engine system 100 is as follows: Figure 1 As shown. Furthermore, the relative positions of the components of the engine system 100 are as follows: Figure 1 As shown. However, it should be understood that the relative positions of the components of the engine system 100 are shown only as an example, and in other embodiments, the components of the engine system 100 may be arranged in a different order and / or the engine system 100 may include more than Figure 1 The number of components shown may be more or less. The location of the components of the engine system 100 is referenced herein. Figure 1 Describe it.
[0055] like Figure 1 As shown, engine system 100 includes coolant system 110. Coolant system 110 includes thermostat housing assembly 200, radiator assembly 130, radiator bypass pipe 132, and downstream components 140. The structure and function of each component of thermostat housing assembly 200 are described herein with reference to... Figures 2 to 7 Describe it.
[0056] Thermostat housing assembly 200 is coupled to the coolant outlet portion 108 of engine 102. Thermostat housing assembly 200 is located downstream of engine 102. Thermostat housing assembly 200 is in fluid receiving communication with the coolant outlet portion 108 of engine 102. Thermostat housing assembly 200 is coupled to radiator assembly 130. Radiator assembly 130 is located downstream of thermostat housing assembly 200. Thermostat housing assembly 200 is in selective fluid communication with radiator assembly 130. Thermostat housing assembly 200 is coupled to radiator bypass pipe 132. Radiator bypass pipe 132 is located downstream of thermostat housing assembly 200. Thermostat housing assembly 200 is in fluid communication with radiator bypass pipe 132.
[0057] Now for reference Figure 2 The image shows a perspective view of a thermostat housing assembly 200. The thermostat housing assembly 200 includes a thermostat housing 210 and a valve assembly 260. The thermostat housing 210 defines a cavity 212. The thermostat housing 210 includes an inlet portion 214, a radiator outlet portion 216, a radiator bypass outlet portion 218, and a housing partition portion 240. The inlet portion 214 has a first port 220 in fluid communication with the cavity 212. The radiator outlet portion 216 has a second port 222 in fluid receiving communication with the cavity 212. In some embodiments, the radiator outlet portion 216 has more than one second port 222 in fluid receiving communication with the cavity 212. The radiator bypass outlet portion 218 has a third port 224 in fluid receiving communication with the cavity 212. The housing partition 240 defines: a first orifice 242 that provides selective fluid communication from the cavity 212 to the second port 222; and a second orifice 244 that provides fluid communication from the cavity 212 to the second port 222.
[0058] In some embodiments, the inlet portion 214, radiator outlet portion 216, radiator bypass outlet portion 218, and housing partition portion 240 of the thermostat housing 210 are formed from a single continuous material. By forming the thermostat housing 210 from a single continuous material, the thermostat housing 210 can be formed without potential leakage paths between the inlet portion 214 and radiator outlet portion 216, between the radiator outlet portion 216 and radiator bypass outlet portion 218, between the inlet portion 214 and radiator bypass outlet portion 218, and between the housing partition portion 240 and radiator outlet portion 216. Advantageously, reducing or mitigating leakage paths in the thermostat housing 210 lowers the likelihood of coolant leaking from the thermostat housing 210 into the surrounding environment. For example, when the thermostat housing 210 is formed of a single continuous material, coolant may not leak from the thermostat housing 210 at the location between the inlet portion 214 and the radiator outlet portion 216, or from the radiator outlet portion 216 and the radiator bypass pipe outlet portion 218.
[0059] Valve assembly 260 is adjustable between a first configuration and a second configuration, the first configuration selectively blocking fluid communication from cavity 212 to second port 222, and the second configuration selectively blocking fluid communication from cavity 212 to third port 224 through first orifice 242. For example, when valve assembly 260 is in the first configuration, first port 220 is in fluid communication with third port 224 through first orifice 242 and second orifice 244. When valve assembly 260 is in the second configuration, first port 220 is in fluid communication with second port 222, and first port 220 is in fluid communication with third port 224 through second orifice 244. In some embodiments, a portion of valve assembly 260 is housed within cavity 212.
[0060] The valve assembly 260 can be adjusted between a first configuration and a second configuration based on the temperature of the coolant in the coolant system 110. For example, when the coolant temperature is below a coolant temperature threshold, the valve assembly 260 can be adjusted to the first configuration, such that the coolant flow received by the thermostat housing assembly 200 is directed to the radiator bypass pipe 132 and does not flow through the radiator assembly 130. When the coolant temperature is above the coolant temperature threshold, the valve assembly 260 can be adjusted to the second configuration, such that a first portion of the coolant flow received by the thermostat housing assembly 200 is directed to the radiator assembly 130, and a second portion of the coolant flow is directed to the radiator bypass pipe 132 through the second orifice 244.
[0061] In some embodiments, the thermostat housing assembly 200 includes an auxiliary valve assembly 270. For example, when the radiator outlet portion 216 of the thermostat housing 210 defines more than one second port 222, the thermostat housing assembly 200 may include a valve assembly 260 and an auxiliary valve assembly 270. The valve assembly 260 is adjustable between a first configuration and a second configuration, the first configuration selectively blocking fluid communication from the cavity 212 to a first second port 222, and the second configuration selectively allowing fluid communication from the cavity 212 to the first second port 222. The auxiliary valve assembly is adjustable between a third configuration and a fourth configuration, the third configuration selectively blocking fluid communication from the cavity 212 to a second second port 222, and the fourth configuration selectively allowing fluid communication from the cavity 212 to the second second port 222. In some embodiments, a portion of the auxiliary valve assembly 270 is housed within the cavity 212.
[0062] The auxiliary valve assembly 270 can be adjusted between a third and a fourth configuration based on the temperature of the coolant in the coolant system 110. For example, when the coolant temperature is below a first temperature threshold, the valve assembly 260 can be adjusted to the first configuration, and the auxiliary valve assembly 270 can be adjusted to the third configuration, such that the coolant flow received by the thermostat housing assembly 200 is directed to the radiator bypass pipe 132 and does not flow through the radiator assembly 130. When the coolant temperature is greater than or equal to the first temperature threshold and less than or equal to a second temperature threshold higher than the first temperature threshold, the valve assembly 260 can be adjusted to the first configuration, and the auxiliary valve assembly 270 can be adjusted to the fourth configuration, such that a first portion of the coolant flow received by the thermostat housing assembly 200 is directed to the radiator bypass pipe 132 (e.g., through the first orifice 242 and the second orifice 244, etc.), and a second portion of the coolant flow is directed to the radiator assembly 130 (e.g., through the second second port in the second port 222, etc.).
[0063] When the coolant temperature is higher than a second temperature threshold, valve assembly 260 can be adjusted to a second configuration, and auxiliary valve assembly 270 can be adjusted to a fourth configuration, such that a first portion of the coolant flow received by thermostat housing assembly 200 is directed to radiator bypass pipe 132 (e.g., through second hole 244, etc.), and a second portion of the coolant flow is directed to radiator assembly 130 (e.g., through the first and second second ports in second port 222, etc.). When valve assembly 260 is in the second configuration and auxiliary valve assembly 270 is in the fourth configuration, the amount of coolant flow directed to radiator assembly 130 can be higher than the amount when valve assembly 260 is in the first configuration and auxiliary valve assembly 270 is in the fourth configuration.
[0064] The thermostat housing assembly 200 includes a thermostat housing 210. A cross-sectional view of the thermostat housing 210 is shown below. Figure 6 and Figure 7 As shown, the cavity 212 of the thermostat housing 210 is a conduit configured to receive coolant flow. The cavity 212 receives coolant flow from an upstream component (such as engine 102). The thermostat housing 210 is configured to selectively supply a portion of the coolant flow (e.g., a first portion of the coolant flow, a second portion of the coolant flow, etc.) to a downstream component (e.g., radiator assembly 130, radiator bypass pipe 132, etc.). For example, the thermostat housing 210 may be configured to selectively supply a first portion of the coolant flow to the radiator assembly 130 and a second portion of the coolant flow to the radiator bypass pipe 132.
[0065] Regardless of the configuration of valve assembly 260, thermostat housing 210 can supply a portion of the coolant flow to radiator bypass pipe 132.

Thus, when the flow rate and / or pressure of the coolant flow received by cavity 212 is higher than the maximum permissible flow rate and / or maximum permissible pressure of radiator assembly 130, a first portion of the coolant flow is directed to radiator bypass pipe 132, regardless of the configuration of valve assembly 260, such that a second portion of the coolant flow supplied by thermostat housing 210 to radiator assembly 130 does not exceed the maximum permissible flow rate and / or maximum permissible pressure of radiator assembly 130. Additionally, since the second portion of the coolant flow supplied to the radiator assembly 130 by the thermostat housing 210 does not exceed the maximum permissible flow rate and / or maximum permissible pressure of the radiator assembly 130, the coolant system 110 may not include additional components configured to reduce the flow rate and / or pressure of the second portion of the coolant flow supplied to the radiator assembly 130 by the thermostat housing 210.

For example, when the valve assembly 260 is in a first configuration, the valve assembly 260 may allow fluid communication from the cavity 212 to the bypass cavity 238 through the first orifice 242 and the second orifice 244. When the valve assembly 260 is in the second configuration, the valve assembly 260 can block fluid communication from the cavity 212 to the bypass cavity 238 through the first orifice 242, while allowing fluid communication from the cavity 212 to the bypass cavity 238 through the second orifice 244.
[0080] The first hole 242 is connected to the axis A of the first hole. A1 Defined. In some implementations, the first hole axis A A1 Oriented parallel to entrance axis A I and / or the first exit axis A O1 In other embodiments, the first hole axis A A1 Orientation is not parallel to the inlet axis A I and / or the first exit axis A O1 (For example, orthogonal, approximately perpendicular, or aligned with the axis of the first hole A) A1 Not parallel to the inlet axis A I and / or the first exit axis A O1 (any non-zero angle).

In one example embodiment, a first ratio between the fourth cross-sectional area of the first aperture 242 and the second cross-sectional area of the second port 222 is between about 0.15 and 0.25, for example, about 0.20.
[0082] The second hole 244 is connected to the axis A of the second hole. A2 Defined. In some embodiments, the second hole axis A A2 Oriented approximately perpendicular to the axis A of the first hole.

O2At that time, the flow rate of the coolant flowing through the second hole 244 may be slower. Because the flow rate of the coolant flowing through the second hole 244 is slower, it can prevent the coolant flowing through the second hole 244 from damaging the thermostat housing 210.
[0084] The second aperture 244 has a fifth cross-sectional area (e.g., a fifth flow area, etc.). In some embodiments, the fifth cross-sectional area of the second aperture 244 is smaller than the fourth cross-sectional area of the first aperture 242.

[0085] In some embodiments, the size of the second orifice 244 may depend on the operating parameters of the engine 102. For example, the second orifice 244 may have a first diameter when the engine system 100 includes a first engine 102 that utilizes a first flow rate of coolant, which is a first amount exceeding a flow threshold of the radiator assembly 130; and the second orifice may have a second diameter greater than the first diameter when the engine system 100 includes a second engine 102 that utilizes a second flow rate of coolant, which is a second amount exceeding a flow threshold of the radiator assembly 130, and this second amount is greater than the first amount. Therefore, by modifying the size of the second orifice 244, the thermostat housing assembly 200 can be used in engine systems 100 that include various engines 102 having various operating parameters.
[0086] The housing partition 240 includes a first partition 246 (e.g., a first portion of the housing partition 240, etc.), a second partition 248 (e.g., a second portion of the housing partition 240, etc.), and a third partition 250 (e.g., a third portion of the housing partition 240, etc.). The first partition 246 faces the second port 222. A first hole 242 extends through the first partition 246. The second partition 248 extends from the first partition 246. A second hole 244 extends through the second partition 248. In some embodiments, the second partition 248 is oriented substantially perpendicular to the first partition 246. In other embodiments, the second partition 248 is oriented not perpendicular to the first partition 246 (e.g., substantially parallel or at any non-ninety-degree angle that allows the second partition 248 to not be perpendicular to the first partition 246). The third partition 250 extends from the second partition 248 and faces the first port 220. In some embodiments, the third partition 250 is oriented substantially perpendicular to the second partition 248 (e.g., parallel to the first partition 246, etc.). In other embodiments, the third partition 250 is oriented not perpendicular to the second partition 248 (e.g., substantially parallel or at any non-ninety-degree angle that allows the third partition 250 not to be perpendicular to the second partition 248).
[0087] In some embodiments, the housing partition 240 is located between the first port 220 and the second port 222. For example, the housing partition 240 may extend into a cavity 212 between the first port 220 and the second port 222, such that coolant flowing through the cavity 212 cannot flow from the first port 220 to the second port 222 along a straight path (e.g., a direct path).

[0089] At process 310, method 300 includes operating a valve assembly in a first configuration.

In other embodiments, the first configuration of the valve assembly selectively blocks fluid communication from the cavity to the radiator bypass through a first orifice in the thermostat housing assembly and allows fluid communication from the cavity to the radiator bypass through a second orifice in the thermostat housing assembly.
[0090] At process 320, method 300 includes adjusting the valve assembly from a first configuration to a second configuration. For example, process 320 may include adjusting valve assembly 260 from the first configuration to the second configuration.
[0091] At process 330, method 300 includes operating the valve assembly in a second configuration. In some embodiments, the second configuration of the valve assembly selectively blocks fluid communication from the cavity to the radiator bypass pipe through a first orifice of the thermostat housing assembly and allows fluid communication from the cavity to the radiator bypass pipe through a second orifice of the thermostat housing assembly. For example, process 320 may include adjusting the valve assembly 260 from a first configuration to a second configuration that selectively blocks fluid communication from the cavity 212 to the radiator bypass pipe 132 through a first orifice 242 of the thermostat housing assembly 200 and allows fluid communication from the cavity 212 to the radiator bypass pipe 132 through a second orifice 244 of the thermostat housing assembly 200.
