Abstract
The utility model discloses a kind of automobile engine valve chamber lid, including housing, housing has groove, several points fire hole is provided with groove, the the first isolation groove crossed by coaming plate is provided with the side of groove, the position of first isolation groove outer wall correspondence fire hole is provided with resigning groove, the the second isolation groove crossed by coaming plate is provided between two fire holes in groove, two adjacent fire holes of second isolation groove outer wall correspondence set two resigning recess respectively, and the connecting hole of several annular arrays is provided with the end face of the first isolation groove and the second isolation groove.So just reach that the position of camshaft drive and variable lift mechanisms to taking automobile engine valve chamber lid is effectively completely cut off, so that the purpose of the normal work of camshaft drive and variable lift mechanisms.
Description
Technical field
The utility model is related to a kind of containment member of automobile engine, and in particular to a kind of automobile engine valve chamber
Lid.
Background technology
The valve actuating mechanism of automobile engine mainly includes valve assembly, cam assembly, camshaft drive, valve and driven
Motivation structure, sensing processor, variable lift mechanisms component and motor-driven mechanism.Inlet and outlet are housed in the upper surface of cylinder cap
Gate seat and valve guide hole, for being installed into, exhaust valve and valve spring etc., are also machined with installation spark plug and spark-plug socket
Fire hole, these structures are closed together with engine cylinder cover by valve-chamber cover and constitute cavaera, and some large-scale engines
Camshaft drive and variable lift mechanisms can take the part of valve-chamber cover, after in-engine machine oil use
It can be contaminated, the machine oil of these pollutions can influence the normal operation of camshaft drive and variable lift mechanisms, therefore
These machine oil are isolated.
The content of the invention
To solve the above problems, the utility model provides a kind of automobile engine valve chamber lid, it is therefore intended that to taking vapour
The camshaft drive of car engine valve-chamber cover and the position of variable lift mechanisms are effectively completely cut off, so that cam
The normal work of shaft transmission and variable lift mechanisms.
To achieve the above object, the utility model provides following technical scheme:A kind of automobile engine valve chamber lid, bag
Housing is included, described housing has groove, several points fire hole is provided with described groove, is provided with the side of the groove
The the first isolation groove crossed by coaming plate, the position of the first isolation groove outer wall correspondence fire hole is provided with resigning groove,
In described groove two described in the second isolation groove crossed by coaming plate, the second isolation groove outer wall pair are provided between fire hole
Two adjacent fire holes are answered to set two resigning recess respectively, provided with some on the end face of the described first isolation groove and the second isolation groove
The connecting hole of individual annular array.
Two seal grooves of the connecting end surface of the shell nozzle provided with annular, provided with sealing in the seal groove described in two
Adhesive tape.
By using having the beneficial effect that above-mentioned technical proposal is reached:First isolation groove is used to be tightly connected camshaft biography
Motivation structure, the second isolation groove is used to be tightly connected variable lift mechanisms so that effectively completely cut off with the machine oil of engine, the first isolation
The outer wall of groove and the second isolation groove has bypassed fire hole by resigning groove and resigning recess respectively, it is ensured that the space of isolation,
Camshaft drive and variable lift mechanisms normal work are ensure that, has so just been reached to taking automotive engine valves
The camshaft drive of chamber cap and the position of variable lift mechanisms are effectively completely cut off so that camshaft drive with
And the purpose of the normal work of variable lift mechanisms.
The utility model is further described with reference to the accompanying drawings and detailed description.
Brief description of the drawings
Fig. 1 is the structure chart of the utility model embodiment.
Embodiment
The utility model is specifically described below by embodiment, is served only for carrying out further the utility model
Explanation, it is impossible to be interpreted as the restriction to the utility model protection domain.
As shown in figure 1, the utility model discloses a kind of automobile engine valve chamber lid, including housing 1, housing 1 has
Groove 11, provided with 3 fire holes 12 in groove 11, the first isolation groove 2 crossed by coaming plate is provided with the side of groove 11, the
The position of one isolation groove 2 outer wall correspondence fire hole 12, which is provided between resigning groove 21, two fire holes 12 in groove 11, to be provided with
The the second isolation groove 3 crossed by coaming plate, two adjacent fire holes 12 of the second isolation groove 3 outer wall correspondence set two resigning recess respectively
31, the connecting hole 4 of several annular arrays is provided with the end face of the first isolation isolation groove 3 of groove 2 and second.
Two seal grooves 5 of the connecting end surface that housing 1 is open provided with annular, fluid sealant is respectively equipped with two seal grooves 5
Bar.The sealing being connected with engine can be so effectively improved, oil leakage is prevented.
In embodiment, the first isolation groove 2 is used to be tightly connected camshaft drive, and the second isolation groove 3 is used for the company of sealing
Connect variable lift mechanisms so that effectively completely cut off with the machine oil of engine, the outer wall difference of the first isolation isolation groove 3 of groove 2 and second
Fire hole 12 is bypassed by resigning groove 21 and resigning recess 31, it is ensured that the space of isolation, it is ensured that camshaft drive machine
Structure and variable lift mechanisms normal work, have so just reached the camshaft drive machine to taking automobile engine valve chamber lid
The position of structure and variable lift mechanisms is effectively completely cut off, so that camshaft drive and variable lift mechanisms are just
The purpose often worked.
