Push-rod hole gasket；The push-rod hole gasket is identical as seal with annular groove mat structure；Multiple oil ducts are equipped between cylinder body and cylinder cap
Hole, each oil hole, which is located at the engaging portion position of cylinder body and cylinder cap, is equipped with oil hole gasket；The oil hole gasket with
Seal with annular groove mat structure is identical.
Further, multiple seal with annular groove pads at multiple cylinder mouths each can be independently arranged, and can be also integrally formed.
Further, seal with annular groove pad is made of plastic material.
Further, flange is equipped at the sealing pad edge.
Further, push-rod hole gasket is made of elastic material.
Further, oil hole gasket is made of elastic material.
Compared with the prior art the present invention has the advantage that
The invention has the advantages of simple structure, compactness and reasonable structure, passes through the structure matching design of cylinder block and cylinder jacket, uses cylinder mouth
Gasket is as high cylinder pressure air seal, in a manner of plastic deformation caused by compensating cylinder, cylinder sleeve, cylinder cap mismachining tolerance
Gap guarantees cylinder seal effect, has good improvement effect to the whole aircraft reliability of engine, discharge, noise etc.；Push rod
Hole and oil hole use the push-rod hole gasket and oil hole gasket of elastic material, play sealing using the flexible deformation of material
Effect；The sealing structure of seal with annular groove pad, push-rod hole gasket and oil hole gasket this three's complex, so that engine is set
Count it is more flexible, convenient for body and cylinder cap heteromorphosis design, increase engine cylinder body volume and stroke, realize the spirit of structure
Arrangement living, while increasing the versatility of components.
