Abstract
The utility model discloses a take engine cylinder lid of sealing washer, the motor end cap comprises a cover body, be provided with the combustion chamber on the lid, the lid is provided with the ring type seal mounting groove around the combustion chamber, be provided with the sealing washer in the sealing washer mounting groove, the sealing washer includes annular reinforcing bar piece, sets up rubber pad and the elasticity steel bluff piece of sealed parcel outside the rubber pad on the face of annular reinforcing bar piece both sides. The utility model discloses a set up the sealing washer around the combustion chamber and come to seal the gas in the cylinder head, seal structure's simple manufacture to the sealing washer utilizes the rubber pad to support elasticity steel bluff piece, and the resilience can be good, and sealed effect is good, the intensity of its elasticity steel bluff piece and annular reinforcing bar piece is good simultaneously for the structural strength of sealing washer is good, and the rubber pad is by the sealed parcel of elasticity steel bluff piece, make its with high temperature gas contact, sealing washer longe -lived, thereby the sealed poor technical problem of big, the sealed effect of the processing degree of difficulty that exists in current cylinder head combustion chamber has been solved.
Description
Technical field
The utility model relates to a kind of engine components, particularly a kind of cylinder cap of motor.
Background technique
Cylinder head is one of main parts size of motor, and major function is sealing cylinder top, and forms firing chamber with piston head together with cylinder.Cylinder head is provided with intake valve and exhaust valve, be provided with valve stem in intake valve and exhaust valve, motor in the course of the work, controls the opening and closing of intake valve and exhaust valve by valve stem, realize from intake valve inhale fresh air or combustion gas, discharge the waste gas after burning from exhaust valve.
In prior art, cylinder head end face is provided with and cooling water channel phase water port in cylinder block and the oilhole that communicates with fuel gallery.Leaking to prevent cylinder head end face from occurring, leaking gas, the problem such as leakage of oil, by stamping out the burr of certain altitude around the firing chamber of cylinder head, water hole and oilhole in prior art, utilize the resiliently deformable of burr to realize sealing, but the rebound elasticity of this relief structure is low, to the hardness of body, cylinder cap and machining surface processing request higher, and sealing effect is poor.
Model utility content
In view of this, the purpose of this utility model is to provide a kind of engine cylinder cover with seal ring, adopts relief structure to seal firing chamber to solve in prior art, there is the technical problem that difficulty of processing is large, sealing effect is poor.
The engine cylinder cover of the utility model band seal ring, comprise lid, described lid is provided with firing chamber, described lid is provided with O-ring seal mounting groove around firing chamber, be provided with seal ring in described seal ring mounting groove, described seal ring comprises annular reinforcing bar sheet, be arranged on rubber pad on annular reinforcing bar sheet bi-side and the Elastic Steel bluff piece of sealed envelope outside rubber pad.
Further, described lid is also provided with the recessed seam coordinated with cylinder liner, described recessed seam is provided with steel plate washer.
Further, the surface of described steel plate washer is provided with annular projection.
Further, described lid is provided with cooling water passage on the oral area side of intake duct and air outlet flue.
The beneficial effects of the utility model:
The engine cylinder cover of the utility model band seal ring, it adopts and around cylinder head upper combustion chamber, arranges seal ring seal combustion gas, the making of sealing configuration is simple, and the seal ring in the utility model utilizes rubber pad to support Elastic Steel bluff piece, make the resilience of seal ring good, sealing effect is good; The intensity of its Elastic Steel bluff piece and annular reinforcing bar sheet is good simultaneously, and make the structural strength of seal ring good, not fragile, and rubber pad is by Elastic Steel bluff piece sealed envelope, and it is not contacted with high-temperature fuel gas, the life-span of seal ring is long; Thus solve existing head combustion chamber sealing there is the technical problem that difficulty of processing is large, sealing effect is poor.
Accompanying drawing explanation
Fig. 1 is the broken section structural representation of the engine cylinder cover of the present embodiment band seal ring;
Fig. 2 is the enlarged diagram in P portion in Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, the engine cylinder cover of the present embodiment band seal ring, comprise lid 1, described lid is provided with firing chamber 2, described lid is provided with O-ring seal mounting groove 3 around firing chamber, be provided with seal ring 4 in described seal ring mounting groove, described seal ring comprises annular reinforcing bar sheet 41, be arranged on rubber pad 42 on annular reinforcing bar sheet bi-side and the Elastic Steel bluff piece 43 of sealed envelope outside rubber pad.
The engine cylinder cover of the present embodiment band seal ring, it adopts and around cylinder head upper combustion chamber, arranges seal ring seal combustion gas, the making of sealing configuration is simple, and the seal ring in the utility model utilizes rubber pad to support Elastic Steel bluff piece, make the resilience of seal ring good, sealing effect is good; The intensity of its Elastic Steel bluff piece and annular reinforcing bar sheet is good simultaneously, and make the structural strength of seal ring good, not fragile, and rubber pad is by Elastic Steel bluff piece sealed envelope, and it is not contacted with high-temperature fuel gas, the life-span of seal ring is long; Thus solve existing head combustion chamber sealing there is the technical problem that difficulty of processing is large, sealing effect is poor.
As the improvement to the present embodiment, described lid is also provided with the recessed seam coordinated with cylinder liner, described recessed seam is provided with steel plate washer 5, can be sealed combustion gas further by steel plate washer, can ensure to start function normally to work when seal ring damages.
As the improvement to the present embodiment, the surface of described steel plate washer is provided with annular projection 6, by the resiliently deformable of annular projection, the sealing effect of steel plate washer can be improved further.
As the improvement to the present embodiment, described lid is provided with cooling water passage 6 on the oral area side of intake duct and air outlet flue, by cooling water channel to lid and seal ring cooling, engine cylinder cover can be avoided because of high temperature failure.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
