Abstract

The invention relates to a novel integrated valve chamber cover. The novel valve chamber cover comprises a cover body (1), wherein at least one camshaft installing hole (3), an air intake rockshaft installing hole (4) and an oil sprayer installing hole (5) are formed in the cover body (1); a baffle plate (2) is arranged inside the cover body (1); the camshaft installing hole (3) and the air intake rockshaft installing hole (4) are formed in the baffle plate (2); the camshaft installing hole (3) is formed on the upper part of the air intake rockshaft installing hole (4); and the oil sprayer installing hole (5) is formed on the top of the cover body (1). The novel integrated valve chamber cover has the advantages that the novel integrated valve chamber cover has a compact structure; a few parts are required to be assembled, so that an assembling process can be simplified; a dimensional chain is shortened, so that installation precision is easy to control compared with that of the conventional structure; and a camshaft and an oil sprayer are convenient to disassemble and can be removed without the removal of related parts such as the valve chamber cover.

Description

[0001] technical field [0002] The invention belongs to a valve chamber cover, in particular to a novel integrated valve chamber cover. Background technique [0003] At present, the traditional valve cover structure does not integrate the camshaft of the valve train, the intake rocker arm and the installation function of the fuel injector. For a diesel engine with an overhead camshaft structure, the camshaft of the valve train is usually installed and positioned through a guide cylinder installed on the cylinder head; for a valve train with a rocker arm structure, the installation of the rocker arm is usually It is realized by direct installation; the injector is usually installed by pressing the pressure plate on the cylinder head. The advantage of adopting this type of structure is that the casting and machining precision of the parts is not high. However, there are also shortcomings: the structure is not compact enough; there are many parts to be assembled; the machini...
