[0002] The air compressor is one of the most important components of a vehicle. With the increase of use time, the air intake valve of a traditional air compressor is difficult to seal. Moreover, the use of a single push rod with a sealing ring leads to a reduced lifespan, making it difficult to achieve the purpose of long-term use. Furthermore, replacement and maintenance are relatively difficult.

[0003] To address the aforementioned issues, a valve assembly for an automotive air compressor is proposed. Utility Model Content

[0004] In order to overcome the shortcomings of traditional air compressor intake valves, which have difficulty in ensuring sealing performance over time, this utility model provides a valve assembly for an automotive air compressor.

[0005] The technical solution of this utility model is as follows: a valve assembly for an automotive air compressor, including a valve body; the valve body consists of a lower valve and an upper valve; the lower valve has a venting chamber in the middle; the lower valve and the upper valve are connected by a sealing plate I and maintain a seal; it also includes a venting plate, a sealing ring, a sealing plate II, a piston spring, a piston, a connecting column, a sealing top, and a valve stem spring; a venting plate is provided on the lower side inside the lower valve; a sealing ring is fixedly connected to the middle of the venting plate; a sealing plate II is fixedly connected to the bottom of the sealing ring; a piston spring is provided inside the sealing plate II; a piston is connected to the middle of the sealing ring; the piston is fixedly connected to the piston spring; a connecting column is fixedly connected to the piston, and the connecting column is slidably connected to the sealing ring; a sealing top is fixedly connected to the upper part of the connecting column; a valve stem spring is fixedly connected to the middle of the lower surface of the sealing top; the valve stem spring is in contact with the piston.

[0006] As a further preferred option, it also includes a retaining ring; a retaining ring is fixedly connected to the lower side inside the lower valve; the retaining ring is fixedly connected to the vent plate.

[0007] As a further preferred option, it also includes a sealing ring I; the sealing ring I is fixed to the top surface of the seal; the upper part of the sealing ring I is chamfered.

[0008] As a further preferred option, the lower surface of the sealing plate I has a groove that matches the sealing ring I for achieving a seal.

[0009] As a further preferred option, it also includes an end cap and an air inlet; the end cap is fixed to the upper surface of the upper valve; an air inlet is opened on the side of the upper valve, and the air inlet is connected to the ventilation chamber.

[0010] As a further preferred embodiment, it also includes a stopper rod; a stopper rod is provided in the middle of the upper surface of the seal; the stopper rod is slidably connected to the upper valve.

[0011] As a further preferred option, the upper part of the piston rod is a T-shaped ring and the lower part is a U-shaped ring.

[0012] As a further preferred option, it also includes a sealing ring II; the upper part of the plug rod is fixed with the sealing ring II.

[0013] As a further preferred option, the end cap is provided with a circular cavity, within which the plug rod can slide.

[0014] This utility model has the following advantages: the sealing top moves upward and finally abuts against the sealing plate I, and the sealing ring I enters the groove on the lower side of the sealing plate I. Under the action of the sealing ring I, in addition to the initial sealing between the sealing top and the sealing plate I, the sealing effect can be enhanced by the sealing ring I. In this process, by adding a plug rod, the air inlet is blocked as the plug rod moves upward. Thus, when the blocking operation is performed, the entire structure has three sealing points, which can increase the sealing effect and also better extend the service life of the structure.

[0021] Example 1

[0022] A valve assembly for an automotive air compressor, such as Figures 1-4 As shown, it includes a valve body; the valve body is composed of a lower valve 101 and an upper valve 201; the lower valve 101 has a vent chamber 103 in the middle; the lower valve 101 and the upper valve 201 are connected by a sealing plate I 202 and are kept sealed.

[0023] It also includes a vent plate 4, a sealing ring 5, a sealing plate II 6, a piston 7, a spring 61, a connecting column 8, a sealing top 9, and a valve stem spring 11; the vent plate 4 is provided on the lower side inside the lower valve 101; the sealing ring 5 is bolted to the middle of the vent plate 4; the sealing plate II 6 is bolted to the bottom of the sealing ring 5; the piston 7 is provided inside the sealing plate II 6; the piston 7 is connected to the middle of the sealing ring 5; the sealing plate II 6 is bolted to the bottom of the sealing ring 5, which ensures that the whole assembly is easy to disassemble, and the piston 7 can be disassembled by simply turning the screws; the piston 7 is fixedly connected to the spring 61; the connecting column 8 is fixedly connected to the piston 7, and the connecting column 8 is slidably connected to the sealing ring 5; the sealing top 9 is fixedly connected to the upper part of the connecting column 8; the valve stem spring 11 is fixedly connected to the middle of the lower surface of the sealing top 9; the valve stem spring 11 is in contact with the piston 7.

[0024] It also includes a retaining ring 3; the retaining ring 3 is bolted to the lower side inside the lower valve 101; the retaining ring 3 is bolted to the vent plate 4; by adding the retaining ring 3, the lower valve 101 is easier to manufacture, and the bolted connection between the retaining ring 3 and the vent plate 4 also facilitates subsequent disassembly and maintenance.

[0025] It also includes a sealing ring I10; the sealing ring I10 is bolted to the upper surface of the sealing top 9; the upper part of the sealing ring I10 is chamfered; the bolted connection design of the sealing ring I10 not only ensures the stability of the sealing ring I10, but also, because the sealing ring I10 is chamfered, it will not get stuck when it is detached from the sealing plate I202, thus improving its service life.

[0026] The lower surface of the sealing plate I202 has a groove that matches the sealing ring I10 for sealing purposes.

[0027] It also includes an end cap 203 and an air inlet 204; the end cap 203 is bolted to the upper surface of the upper valve 201; the upper valve 201 has an air inlet 204 on its side, and the air inlet 204 is connected to the ventilation chamber 103.

[0028] It also includes a stopper rod 12; the stopper rod 12 is provided in the middle of the upper surface of the sealing top 9; the stopper rod 12 is slidably connected to the upper valve 201; in addition to simply blocking the air inlet 204, the stopper rod 12 also seals the upper valve 201 during the air passage process, and further reduces the space of the upper valve 201 during the air passage process, thereby improving the gas flow efficiency.

[0029] The upper part of the stopper rod 12 is a T-shaped ring, and the lower part is a U-shaped ring.

[0030] It also includes a sealing ring II13; the upper part of the plug rod 12 is bolted with a sealing ring II13.

[0031] The end cap 203 has a circular cavity, and the plug rod 12 can slide within the cavity of the end cap 203; this ensures that the plug rod 12 is not locally fixed during the entire movement process, but is restricted throughout the entire movement process, so that it can still maintain a good sealing and stability effect under certain vibration.

[0032] It should be noted that the entire valve body is connected to the air compressor via a connecting ring 102, and the connection method is a bolt connection.

[0033] This invention features an air inlet 204 on the upper valve 201, allowing gas to enter the cavity of the ventilation chamber 103 from the side. The gas is then transported through a circular through-hole on the ventilation plate 4, altering the traditional air intake channel. When a sealing operation is required, the electronically controlled valve supplies gas to the sealing ring 5. Under the action of the gas, the piston 7 moves upward, driving the connecting column 8 and the sealing top 9 to move. The sealing top 9 moves upward and finally comes into contact with the sealing plate I 202. The sealing ring I 10 enters the groove on the lower side of the sealing plate I 202. Under the action of the sealing ring I 10, in addition to the initial sealing between the sealing top 9 and the sealing plate I 202, the sealing effect can be enhanced by the sealing ring I 10. During this process, a stopper rod 12 is added. As the stopper rod 12 moves upward, it blocks the air inlet 204. Thus, when a blocking operation is performed, the entire structure has three sealing points, which can increase the sealing effect and extend the service life of the structure.

These descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
