Description
Technical Field
The present invention relates to a thermostat assembly. And more particularly, to a thermostat assembly having a pressure balanced sleeve valve for controlling circulation of coolant fluid of an internal combustion engine.
Background
As is well known, a thermostat assembly is the primary control device of the cooling cycle unit, which is used to control engine temperature during combustion. The coolant circulating in the engine block and the cylinder head absorbs heat generated by combustion in the engine block and the cylinder head, and the coolant will have a temperature increase due to the absorption. With respect to the temperature of the coolant, the thermostat assembly can maintain the temperature of the coolant within a desired range by adjusting the flow to the sub-circuit outlets (radiator and bypass outlet).
An important criterion for implementing an optimal thermostat mechanism is to achieve a low pressure drop at the required flow rate with a lower driving force requirement. Different types of valve structures (e.g., poppet valves, sliding valves, and sleeve valves) are used to achieve this optimization goal.
The driving force required to lift the valve-type thermostat assembly should be at least equal to the hydraulic pressure exerted by the coolant on the valve plate, which is equal to the coolant pressure times the valve spray area. To achieve a low pressure drop, the injection area of the valve should be increased, which will result in a significant increase of the required driving force by the valve structure of the poppet valve. The required driving force is generated by a wax-based drive or an electromechanical drive. To obtain a high driving force, a more bulky driver is required, which results in a significant increase in cost and impairs compactness of the product.
Another obvious type is a sliding valve thermostat assembly, which is actually a plate valve with open windows or holes that allow coolant to pass through and perform a sliding motion on a seat created by the body or by other seat structure. While this type of valve allows a larger injection area so that a lower pressure drop is achieved with a lower actuating force, it is not a reliable and economical solution due to the complex valve structure requirements and wear problems caused by sliding under high hydraulic loads.
The sleeve valve structure has a pressure balancing feature that is continuously of the same cross-section during the opening and closing movement of the valve and allows for lower demands on actuation force while increasing the size of the valve to achieve low pressure drop at high flow rates relative to poppet type structures. Unfortunately, the known construction of sleeve valves is costly due to the complexity of the mechanism and, because of the long-term reliability that is desired, metal-to-metal contact is preferably chosen so that the amount of leakage through the valve when it is closed is very large.
Disclosure of Invention
In the present invention, the basic structure of the sleeve valve structure is achieved by using a simple mechanical structure, thereby achieving zero leakage when closing the valve, which improves reliability and reduces product cost, and in addition, achieves lower pressure drop and higher flow rate, while also increasing flow through the valve.

A thermostat assembly with a pressure balanced sleeve valve structure (1) enabling dual flow for use as an assembly in an internal combustion engine cooling system, which assembly allows both external and internal flow, thereby enabling lower pressure drop at higher flow rates, and can be essentially considered as a concentric dual valve structure allowing dual port opening. By implementing the present invention, one will obtain an easy to use, leak-proof thermostat assembly that achieves low pressure drop at high flow rates.
The driver (T) is placed on the lower body (22) through the guide hole (222). Then, by positioning the pressure equalizing passage (31) above the driver (T), the upper body (21) guides the valve seat (3) by the inner guide protrusion (212). The upper body (21) and the lower body (22) are assembled by welding. This structure and its inner part are assembled by engaging the hole of the upper end of the valve seat (3) and the guide projection (P) of the body. Then, the spring (S) is placed at the lower end of the driver (T) and fixed in the body (D) by the spring fixing device (G).
The second sealing element (32) is fitted to the valve seat (3) to provide a seal when the radiator outlet (R) is closed. As shown in fig. 4, the valve seat (3) is hollow at its bottom side in the middle to provide a guide for the driver (T).
When a temperature rise occurs, the actuator (T) will start to lift its piston. The lifting force begins to move the sleeve valve (2) downward and causes the ports on the inner side (where the inner surface of the sleeve valve (2) contacts the sealing elements of the valve seat (3)) and the outer side (where the valve seat structure of the valve seat (3) makes point contact with the top end of the sleeve valve (2)) to open. The simultaneous opening of the two ports provides a pressure equalization function and achieves a low pressure drop at high flow rates.
If the radiator outlet (R) is closed, the end of the sleeve valve (2) is fixed by the valve seat structure of the valve seat (3). On both sides there is coolant pressure, whereby leakage is hindered, and on the other hand the second sealing element (32) provides sealing for the inner side, while the outer side has no sealing precaution.
The body (D) has a radiator outlet (R), an inlet (G) and a bypass outlet (B).
In another embodiment of the invention, a thermostat assembly with a pressure balanced sleeve valve structure (1) enabling dual flow is composed of a valve seat (3) and a sleeve valve (2) by a bonding or fastening method.

The bottom surface of the body (D) is configured accordingly at the location where the thermostat assembly with a pressure balanced type sleeve valve structure (1) enabling dual flow is mounted, except for the provision of an inlet (I) at the bottom surface.
At least one, and preferably two, bypass outlet windows (W) are provided in the side surface to allow coolant to flow through the bypass outlet (B) when the bypass outlet (B) is open. The bypass outlet (B) is shaped as a hose, preferably made of plastic, and is assembled to the main body (D), preferably by welding, on the side of the bypass outlet window (W). The end of the bypass outlet (B) is shaped to be suitable for connection to a hose. The radiator outlet (R) is located at the end of the body (D) and also has a hose geometry protruding from the body (D). The end points of the radiator outlets (R) also have a suitable shape to allow connection.
A guide projection (P) of the main body is provided in the inner space of the main body (2) and projects from the top side of the inner side of the main body (D) through the inner side. The guide projection (P) of the body provides a correct mounting condition for the pressure-balanced type sleeve valve structure (1) with double action by winding the inner portion of the valve seat (3). The bottom surface of the guide protrusion (P) of the main body is provided with a hole having a diameter slightly larger than that of the pin of the driver (T) to facilitate the guide of the driver (T).
A pressure-balanced sleeve valve structure (1) with dual flow is obtained by assembling a valve seat (3) and a sleeve valve (2). The second sealing element (32) is assembled around a valve seat (3) made of an elastomeric compound. At the same time, the first sealing element (214) is assembled around the sleeve valve (2) made of elastomeric compound.
The sleeve valve (2) is assembled from an upper body (21) and a lower body (22). The interior of the assembly provides a space in which the interior portion of the valve seat (3) and the actuator (T) are placed.
When assembled, the valve seat (3) and the sleeve valve (2) can be joined without additional fastening means or fasteners, thereby achieving an easy to apply and cost-effective solution.
The outer part of the valve seat (3) is shaped inside the body (D) and the sleeve valve (2) and the body (D) are in contact when the radiator output (R) is closed, this being called the tilting zone (4). The inner part of the valve seat (3) is assembled inside the sleeve valve (32) and provides the valve seat for the sleeve valve (2) from the inner surface. There are at least six pressure equalization channels (31) shaped to help provide uniform flow.
The upper body (21) of the sleeve valve (2) has at least one curtain bypass valve (211) protruding from the outside of the upper body (21) to control the flow through the bypass outlet (B), at least three (preferably, four) inner guide protrusions (212) protruding from the inside of the upper body (21) providing guidance for the valve seat (3) and the flow passage, and at least one outer guide protrusion (213), the outer guide protrusion (213) providing correct assembly of the sleeve valve (2) and the valve seat (3) inside the body (D).
The lower body (22) of the sleeve valve (2) has at least four pressure compensation windows (221), the pressure compensation windows (221) being provided on the bottom surface with a hollow interior to allow a flow to flow in, and at least one drive guide opening (222), the diameter of the drive guide opening (222) provided on the bottom surface with a hollow interior being slightly larger than the diameter of the shank portion of the drive (T). The pressure balance window (221) controls the parallel flow according to the axis of motion of the sleeve valve (2).
Preferably, the upper body (21) and the lower body (22) are made of plastic and are assembled to each other, preferably by welding. The inner part of the double contact valve seat (3) and the driver (T) are placed inside the sleeve valve (2), and then the sleeve valve upper body (21) and lower body (22) are welded together. Thus, a pressure-balanced sleeve valve structure (1) with dual flow is achieved. The assembly is placed in the body (D) such that the guide protrusion (P) of the body passes through the hollow of the inner portion of the double contact valve seat (3). The bottom of the guide projection (P) of the body is provided with a hole having an inner diameter slightly larger than the outer diameter of the pin of the driver (T). The pin of the driver (T) is guided by this hole. Thereafter, the spring (S) is placed so that it surrounds the rod of the actuator (T) and is locked by the spring fixing means (G).
The sleeve valve (2) includes an upper body (21) and a lower body (22) and controls flow through a radiator outlet (R) and a bypass outlet (B). By the downward movement of the sleeve valve (2), the port between the body (D) and the outside of the sleeve valve (2) and the port between the double contact valve seat (3) and the inside of the sleeve valve (2) are opened simultaneously. Thus, a low pressure drop with a high flow rate may be provided.
A valve seat (3) for controlling the flow passing through the radiator outlet (R) is incorporated inside the sleeve valve (2). The other part of the valve seat (3) is the inner part of the valve seat (3), which is a hollow cylinder, which protrudes above it, has an inner diameter larger than the guide projection (P) of the body, and an outer diameter small enough to be intertwined with the sleeve valve (2).
Preferably, the inner part of the valve seat (3) has six pressure balancing channels (31) which are able to provide a uniform flow. The second sealing element (2) is assembled to provide a seal.
