The sealing plate cover, the sealing plate body, the locking pin positioning sleeve and the pin can reduce friction and wear, thereby helping to extend the service life of the intake camshaft adjuster.

[0007] In the above-mentioned intake camshaft adjuster, the positioning mechanism includes a cylinder, the cylinder is fixedly connected to the top of the sealing plate, and a guide cylinder is fixedly connected to the right side of the cylinder. In practical applications, by providing the cylinder and the guide cylinder, the cam body and the camshaft adjuster can be more easily aligned when docking, thereby providing convenience to the operator and facilitating the connection process.

[0008] In the above-mentioned intake camshaft adjuster, a pin is provided through the surface of the cam body, and the left side of the pin passes through the sealing plate. In practical applications, the cam body can be connected to the camshaft adjuster by providing the pin, which is beneficial to the use of the device.

[0009] In the above-mentioned intake camshaft adjuster, a circular hole is provided on the right side of the sealing plate. In practical applications, by providing the sealing plate, the leakage of the product can be reduced, and the friction torque is also significantly improved. The number of the circular holes is several.

[0010] In the above-mentioned intake camshaft adjuster, the left side of the torsion spring is fixedly connected to the inner cavity of the sealing plate cover, and the right side of the torsion spring is in contact with the sealing plate body. In practical applications, by providing the torsion spring, torque and rotational force can be provided, thereby improving the practicality of the device.

[0011] In the above-mentioned intake camshaft adjuster, a through hole is provided on the left side of the sealing plate cover. In practical applications, by providing the sealing plate body, the sealing plate cover and the locking pin positioning sleeve, the wear of the sealing plate can be reduced, which is beneficial to prolonging the service life of the camshaft adjuster, and the left side of the cam body is in contact with the sealing plate body.

[0012] Compared with the prior art, the advantages of the intake camshaft adjuster are: it can reduce friction and wear during operation, which is beneficial to prolonging the life of the camshaft adjuster and promoting the use of the camshaft adjuster. BRIEF DESCRIPTION OF THE DRAWINGS
