Description

Technical Field

[0001] The utility model relates to the technical field of valve chambers, in particular to a valve chamber cover. Background Art

[0002] The valve cover is mainly used to seal the cylinder head to prevent foreign matter from falling into the engine, and plays the role of sealing the cylinder head. It includes an intake valve cover and an exhaust valve cover, and both the intake valve cover and the exhaust valve cover include a top wall, a side wall and an end wall. The end wall is the wall at both ends of the valve cover. The oil baffle in the intake valve cover mainly separates the lubricating oil and the crankcase exhaust gas, and is arranged parallel to the top wall of the intake valve cover, so that the lubricating oil continues to remain in the engine, and the crankcase exhaust gas is discharged out of the cylinder; the traditional valve cover has a simple internal structure, and the oil baffle and the side walls, end walls and top walls of the valve cover are relatively flat. The lubricating oil splashed from the camshaft located below the valve cover is difficult to form a water drop shape on the flat inner wall of the valve cover, and drips on the camshaft journal and base circle, which cannot fully lubricate the camshaft, resulting in a loud friction sound when the camshaft rotates, and the sound of the entire engine is relatively loud.

[0003] The existing gasoline engine valve chamber cover can refer to the Chinese utility model patent with the authorization announcement number CN203374382U, which discloses a gasoline engine valve chamber cover, including an intake valve chamber cover and an exhaust valve chamber cover with a top wall, a side wall and an end wall, an oil baffle plate is arranged in the intake valve chamber cover parallel to its top wall, and reinforcing ribs are arranged on the lower part of the oil baffle plate and the side wall and top wall of the exhaust valve chamber cover. The utility model overcomes the shortcomings of the existing gasoline engine valve chamber cover that the inner wall is flat, the lubricating oil is difficult to form a water drop shape to lubricate the camshaft, resulting in poor lubrication effect and large friction sound in the valve chamber cover, and provides a gasoline engine valve chamber cover with good lubrication effect and effective reduction of friction sound.

[0004] When the above-mentioned device is in use, it is difficult for the lubricating oil to form a droplet shape to lubricate the camshaft, resulting in poor lubrication effect and loud friction noise in the valve cover. At the same time, due to the simple and compact structure of the device, the device can be directly connected by socketing the intake valve cover and the exhaust valve cover of the end wall, which reduces the socketing stability of the device and the connection stability of the device after long-term use, thereby enhancing the practicality of the device.
