Description

The cylinder head ligand
Technical field
The present invention relates to motor and gas compressor field, especially a kind of cylinder head ligand.
Background technique
The cylinder head of the distribution device of conventional piston formula motor and piston gas compressor and cylinder normally are formed by connecting through head gasket and cylinder bolt; This structure is widely used; But because head gasket damages easily; And in order to ensure sealing, make the cylinder bolt pretightening force be in higher level, so that the cost of the effective sealing between cylinder and the cylinder head increase substantially.Moreover, along with improving constantly and the raising of piston gas compressor pressure of the explosion pressure of motor, the Placement of traditional head gasket and cylinder bolt can not meet the demands.Its one of the main reasons is owing to be under the higher state in the cylinder bolt pretightening force; Cylinder cap also receives bigger moment of flexure, and this moment of flexure is consistent to the active force that cylinder cap produced with cylinder pressure to the direction of the active force that cylinder cap produced, in other words; In this structure; Cylinder head not only will be born the effect of cylinder pressure, but also the effect of the moment of flexure that is produced will bear the cylinder bolt pretension time, this just reduces the strength of cylinder cap to detonation pressure in the cylinder greatly.Therefore, need invention a kind of simple in structure, and can eliminate the novel cylinder head ligand of cylinder bolt pretension the moment of flexure that cylinder cap produced.
Summary of the invention
In order to address the above problem, the technological scheme that the present invention proposes is following:
