Problems solved by technology

[0002] The cylinder head and cylinder of the gas distribution mechanism of traditional piston engines and piston gas compressors are usually connected by cylinder gaskets and cylinder head bolts. This structure has been widely used, but because the cylinder gasket is easily damaged, the cylinder head The cost of bolt processing is high, and the installation procedure is complicated and strict, so the cost of the effective connection between the cylinder and the cylinder head is greatly increased
Not only that, with the continuous increase of the explosion pressure of the engine and the increase of the pressure of the piston gas compressor, the connection method of the traditional cylinder head gasket and cylinder head bolts can no longer meet the requirements
Although there is a technical solution to integrate the cylinder head and the engine block, due to the difficulty in processing, especially the inability to achieve effective molding in the casting process, this technical solution has not received much practical application

Embodiment 1

[0058] Such as figure 1 The shown cylinder head suiting body includes a body 1, a cylinder liner 2 and a cylinder head 3, a sealing bearing closing structure 4 is provided at the upper opening of the cylinder hole 61 of the body 1, and the cylinder head 3 is arranged on the The cylinder liner 2 is in bearing and sealing fit with the sealing bearing closing structure 4 , and the cylinder head 3 is provided with an intake valve 7 and an exhaust valve 8 .

[0059] In this embodiment, the installation method of the cylinder head 3 is different from the installation method of the traditional cylinder head. First, the cylinder liner 2 is pressed into place from the bottom of the cylinder hole 61, and then the cylinder head 3 is installed in place from the bottom of the cylinder hole 61. The bottom of the cylinder liner 2 is plugged into a position that is in sealing and bearing fit with the sealing and bearing closing structure 4 .

Embodiment 2

[0061] Such as figure 2 The shown cylinder head suit body includes a body-cover integrated body 6 and a cylinder head 3, and a sealing load-bearing closing structure 4 is provided at the upper opening of the cylinder liner 2 of the body-cover integrated body 6, and the cylinder head 3 It is arranged in the cylinder liner 2 of the body-cover integrated body 6 and is in load-bearing and sealing cooperation with the sealing bearing closing structure 4 , and an intake valve 7 and an exhaust valve 8 are arranged on the cylinder head 3 .

[0062] In this embodiment, the installation method of the cylinder head 3 is different from the installation method of the traditional cylinder head. Location.

Embodiment 3

[0064] Such as image 3 The difference between the shown cylinder head fitting body and Embodiment 2 is that an intake valve 7 and an air supply valve 9 are provided on the cylinder head 3, and the cylinder head fitting body is used for a gas compressor to output compressed gas.

Abstract

The invention discloses a cylinder cover set matching body, which comprises a machine body, a cylinder jacket and a cylinder cover, wherein a sealing load-bearing closing structure is arranged on an upper opening of a cylinder hole of the machine body and / or an upper opening of the cylinder jacket, and the cylinder cover is arranged in the cylinder jacket and is matched with the sealing load-bearing closing structure(s) in a load-bearing sealing way. The cylinder cover set matching body disclosed by the invention has a simple structure, and a traditional cylinder gasket and a traditional cylinder bolt are omitted, so that the load-bearing pressure of a cylinder can be greatly improved; and if the cylinder cover is formed by adopting casting processing, and since in the invention, one cylinder cover corresponds to one cylinder, the volume and the complexity of the cylinder cover can be greatly reduced, and the rejection rate in a casting process is reduced. In the invention, the volume of the cylinder cover is greatly reduced, so that materials with higher performances can be adopted, the performance of an engine is improved, and the cost of the engine cannot be too high.

Description

technical field [0001] The invention relates to the field of engines and gas compressors, in particular to a gas distribution mechanism. Background technique [0002] The cylinder head and cylinder of the gas distribution mechanism of traditional piston engines and piston gas compressors are usually connected by cylinder gaskets and cylinder head bolts. This structure has been widely used, but because the cylinder gasket is easily damaged, the cylinder head The cost of bolt processing is high, and the installation procedure is complicated and strict, so the cost of effective connection between the cylinder and the cylinder head is greatly increased. Not only that, but with the continuous increase of the explosion pressure of the engine and the increase of the pressure of the piston gas compressor, the connection method of the traditional cylinder head gasket and cylinder head bolts can no longer meet the requirements. Although there is a technical scheme of integrating the ...
