Abstract
The utility model discloses a valve cage cover of an automobile engine, which comprises a valve cage cover (1) and a valve cage cover gasket. The faying face between the valve cage cover (1) and the engine cylinder cover is provided a sealing gasket groove (3) completely matching to the forms of the valve cage cover gasket (2), the sealing gasket groove (3) is enclosed on the faying face between the valve cage cover (1) and the engine cylinder cover, the valve cage cover gasket (2) is fully filled in the sealing gasket groove (3) and the exposed surface is higher than the surface of the valve cage cover (1) and the cylinder cover seal. With the above technical proposal, the utility model can achieve more reliable sealing, more convenient processing, reduce assembling time and processing costs while also can be dismantled and exchanged.
Description
Technical field
The utility model relates to automobile chassis, and more particularly, the utility model relates to a kind of automotive engine valves chamber cover cap.
Background technique
The distribution device of motor car engine comprises valve assembly, cam assembly, camshaft drive and valve actuating mechanism.In the upper-end surface of cylinder cap inlet and outlet gate seat and valve guide hole are housed, be used for installation, exhaust valve and inlet and outlet road etc., also be processed with the hole that spark plug is installed, these structures are sealed with engine cylinder cover by valve chamber cover and are constituted valve cage, require to have excellent sealing performance.
At present, valve chamber cover and valve chamber cover pad are to produce respectively, and then assemble assembling.This need distinguish molding and forming valve chamber cover and valve chamber cover pad, again the valve chamber cover pad is embedded in the sealing gasket film trap of valve chamber cover, because being moulding, the valve chamber cover pad embeds later on, so its shape and sealing gasket film trap can not fit like a glove, and influence its sealing effect.In addition, arrange to embed assembly technology separately, strengthen processing cost.
The model utility content
Problem to be solved in the utility model provides a kind of automotive engine valves chamber cover cap, its objective is to improve sealing effect, reduction processing and assembly cost.
To achieve these goals, the technological scheme that the utility model is taked is: this automotive engine valves chamber cover cap that is provided comprises valve chamber cover and valve chamber cover pad, establish the sealing gasket film trap on the junction plane of valve chamber cover and engine cylinder cover, the sealing gasket film trap forms the shape of sealing on the junction plane of valve chamber cover and engine cylinder cover, described valve chamber cover pad and gasket seal groove shape fit like a glove and are full of the sealing gasket film trap, and its surface of exposing is higher than the surface of valve chamber cover and cylinder cap sealing.
The material of described valve chamber cover pad is two kinds of different materials with the material of valve chamber cover, and the valve chamber cover pad is that flexible, volume can compress, and valve chamber cover is a solid.
Described valve chamber cover pad is a straight forming in the sealing gasket film trap of valve chamber cover.
Adopt technique scheme, make the utility model sealing more reliable, process conveniently, reduced installation time, reduced processing cost, the while still can dismantle and change.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of cyclinder head cover pad shown in Figure 1.
Number in the figure is: 1, valve chamber cover, 2, the valve chamber cover pad, 3, the sealing gasket film trap.
Embodiment
Shown in the structural representation of the cyclinder head cover pad of the structural representation of the present utility model of Fig. 1 and Fig. 2, the utility model is a kind of automotive engine valves chamber cover cap, comprise valve chamber cover 1 and valve chamber cover pad 2, establish sealing gasket film trap 3 on the junction plane of valve chamber cover 1 and engine cylinder cover, sealing gasket film trap 3 forms the shape of sealing on the junction plane of valve chamber cover 1 and engine cylinder cover.Valve chamber cover 1 seals the formation valve cage with engine cylinder cover, requires to have excellent sealing performance.
The utility model is for the reliability that improves sealing and cut down finished cost, and takes following embodiment:
Valve chamber cover pad 2 fits like a glove with sealing gasket film trap 3 shapes and is full of sealing gasket film trap 3, and its surface of exposing is higher than the surface of valve chamber cover 1 and cylinder cap sealing.Guaranteed the reliability of sealing like this.
The material of valve chamber cover pad 2 is two kinds of different materials with the material of valve chamber cover 1, and valve chamber cover pad 2 is that flexible, volume can compress, and valve chamber cover 1 is a solid.When valve chamber cover 1 is pressed on engine cylinder when covering, between valve chamber cover pad 2 and the sealing gasket film trap 3 without any the gap.
Valve chamber cover pad 2 is straight formings in the sealing gasket film trap 3 of valve chamber cover 1.Its concrete processing method is at first with valve chamber cover 1 molding and forming, then valve chamber cover 1 being added wet process, is mold insert with valve chamber cover 1, again in another mould, liquid state is vulcanized rubber injection enter in the sealing gasket film trap 3, form valve chamber cover pad 2.
The utility model adopts technique scheme, makes sealing more reliable, process conveniently, has reduced installation time, has reduced processing cost, and the while still can dismantle and change.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technological scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
