Problems solved by technology

In the prior art, the spring is usually set on the outer wall of the valve stem, and the two are split structures. During the working process of the engine, the lift of the intake valve cannot be adjusted, so it is generally installed on the engine to improve engine performance and change The opening time of the gas throttle and the delayed closing mechanism of the gas throttle. This method has a complex structure design, high cost, and poor adjustability of the gas throttle, which cannot meet the needs of most working conditions.

Abstract

The invention provides an aero-engine, an air intake valve and an air intake structure of the aero-engine. It has a cavity structure. The cavity structure includes a large cavity and a small cavity. The joint sleeve, the elastic piece and the limit blocking plug are sequentially and mutually contacted and loaded into the large cavity. The air intake rod includes a large rod body and a small cavity. The rod body and the small rod body are connected to the joint sleeve through the small cavity. Under the action of the elastic member, the air intake seat can reciprocate along the air intake rod, and its reciprocating stroke is limited between the step and the left end surface of the joint sleeve. . The air intake structure includes an oil-air mixing cavity formed by the pipe wall of the oil-air mixing cavity and an intake valve arranged in the oil-air mixing cavity. The aeroengine has the aeroengine intake structure. The invention can automatically control the opening of the gas throttle passage, thereby optimizing combustion and improving engine performance, and has compact structure and low cost.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an aeroengine, an air intake valve and an air intake structure of the aeroengine. Background technique [0002] Aero-engine (aero-engine) is a highly complex and precise thermal machinery. As the heart of an aircraft, it is not only the driving force for aircraft flight, but also an important driving force for the development of aviation. Every important change in the history of human aviation is related to The technological progress of aero-engines is inseparable. The intake valve of the engine is a very important part of the engine, and it plays a very important role. In the prior art, the spring is usually set on the outer wall of the valve stem, and the two are split structures. During the working process of the engine, the lift of the intake valve cannot be adjusted, so it is generally installed on the engine to improve engine performance and change The opening time of the...
