Embodiment
Fig. 1 is the structural representation of the cylinder head cover sealing gasket of the embodiment of the utility model one.Fig. 2 is the utility model one
The cylinder head cover sealing gasket assembling schematic diagram of embodiment.Fig. 3 is the partial enlarged drawing of A in Fig. 2.As shown in Fig. 2 referring also to figure
3, the utility model provides a kind of cylinder head cover sealing gasket 2, installed in vehicle motor cylinder head 3 and valve mechanism cover 1 it
Between, the cylinder head cover sealing gasket 2 is cyclic structure, and the cylinder head cover sealing gasket 2 has first surface 21 and second surface
22, the first surface 21 is the surface contacted with the cylinder head 3, and the second surface 22 is to be connect with the valve mechanism cover 1
Touch surface, be provided with plurality of sealing lines at the first surface 21, and in the plurality of sealing lines arbitrary neighborhood two sealing lines
Between be provided with oil storage tank 6, prevented by the plurality of sealing lines outside the lubricating oil in the cylinder head 3 and the valve mechanism cover 1
Let out, a small amount of lubricating oil is stored by the oil storage tank 6.
2 structure annular in shape of cylinder head cover sealing gasket of the present utility model, has first surface 21 and a second surface 22, and first
Plurality of sealing lines is provided with surface 21, and is provided with oil storage tank 6 in the plurality of sealing lines between two sealing lines of arbitrary neighborhood,
The plurality of sealing lines prevents the cylinder head 3 from being leaked with the lubricating oil in the valve mechanism cover 1, and the oil storage tank 6 can be deposited
The lubricating oil to leak on a small quantity is stored up, i.e., cylinder head cover sealing gasket 2, which is provided with twice, prevents the barrier of oil leak, enhances the gas
The sealing of cylinder cover hood seal gasket 2.
In one embodiment, parallel superposition is set between the plurality of sealing lines of the present utility model, described a plurality of close
The sealing lines sealed in line are main seal line 4, and remaining seal line is second line of seal 5.The cross section of the primary seal line 4
Triangular in shape, the height of the primary seal line 4 is higher than the second line of seal 5, and the height of the second line of seal 5 is equal.Enter
One step, the quantity of the plurality of sealing lines for three and in a ring runway shape, between three sealing lines parallel superposition set
Put, the seal line among three sealing lines is main seal line 4, and the seal line of both sides is second line of seal 5.The primary seal
The cross section of line 4 is triangular in shape, and under the effect of bolt lock compaction forces, the compressive deformation of primary seal line 4 is relatively small so that institute
Stating the oil storage tank 6 between primary seal line 4 and the second line of seal 5 will not become too small, can be with described in better seal
Cylinder head 3 and the valve mechanism cover 1.Further, the height of the primary seal line 4 is higher than the second line of seal 5 of both sides,
The height of the second line of seal 5 of both sides is equal.
As shown in Fig. 2 the cylinder head 3, the valve mechanism cover 1 and the cylinder head cover sealing gasket 2 are filled by connecting bolt
It is fitted on together, the cylinder head cover sealing gasket 2 is pressed between the cylinder head 3 and the valve mechanism cover 1, in bolt for a long time
To lock under pressure, compression set can occur for its seal line, during real-world operation, each several part of valve mechanism cover 1
Between pressure differential influence and vehicle motor work long hours after can also cause the deformation of seal line, so always there is a small portion
Lubricating oil of sharing in the benefit can be revealed, but the lubricating oil now revealed will be flowed between the primary seal line 4 and the second line of seal 5
In the oil storage tank 6 and it is stored up.Because the cross section of the primary seal line 4 is triangular in shape, even in bolt lock compaction forces
Under effect, its deformation is also relatively small, ensures that the space of the oil storage tank 6 between primary seal line 4 and second line of seal 5 will not become
Must be too small, meanwhile, oil storage tank 6 is a close encapsulation ring structure, when a certain parts of lubricating oil is seeped into the storage in the cylinder head 3
When amount in oil groove 6 is larger, lubricating oil can also flow to other parts in ring and excessively spill over the external world so as to reduce local permeability
Possibility, strengthen the store oil ability of the oil storage tank 6, improve sealing effectiveness, extend the use of cylinder head cover sealing gasket 2
Life-span.
Further, boss type structure is provided with the second surface 22, the cylinder is increased by the boss structure
The compression height of cover gasket 2, also ensure can effectively to fill the valve mechanism cover when cylinder head cover sealing gasket 2 compresses close
The installation concave station of packing 2.Further, the bottom of the boss type structure is semi-cylindrical hill 7, may be alternatively provided as curved knot
The projection of structure.
Cylinder head cover sealing gasket 2 of the present utility model is by being interference fitted the seal line of the cylinder head cover sealing gasket 2
Corresponded to respectively with boss type structure and firmly load with cylinder head 3 and valve mechanism cover 1, increase the cylinder head cover sealing gasket
2 sealing.
So far, although those skilled in the art will appreciate that herein it is detailed have shown and described it is of the present utility model more
Individual exemplary embodiment, still, still can be public according to the utility model in the case where not departing from the spirit and scope of the utility model
The content opened directly determines or derived many other variations or modifications for meeting the utility model principle.Therefore, this practicality is new
