[0002] The valve cover is installed above the cylinder head. It mainly prevents the lubricating oil of the valve rocker mechanism from leaking out and prevents external dust from entering the cylinder and the engine body. At the same time, it plays a great role in ensuring the normal operation and service life of the crankshaft. The main body of the valve cover is provided with two chambers, which are separated from each other by a partition plate. Each chamber has a labyrinth structure for oil and gas pre-separation, and an oil baffle is covered above the two chambers. The oil baffle is also called a partition plate or a liner, which is mainly used to prevent the leakage of engine oil and gas.

[0003] The existing valve cover usually uses ultrasonic welding or glue bonding to connect the isolation plate to the valve cover. However, since the entire engine vibrates when the engine is working, the vibration is transmitted to the isolation plate through contact, causing the isolation plate to loosen or even fall off.
