Novel energy internal combustion engine shield ring

Abstract

The invention discloses a novel energy internal combustion engine shield ring. The novel energy internal combustion engine shield ring comprises an annular shield ring body, an annular boss protrudesand stretches at the top end of the shield ring body, the inner wall of the annular shield ring body comprises a first linear segment inner wall, an oblique line inner wall and a second linear segmentinner wall which are sequentially distributed from top to bottom, the first linear segment inner wall is connected to the oblique line inner wall through a first arc segment inner wall, the oblique line inner wall is connected with the second linear segment inner wall through a second arc segment inner wall, a first horizontal segment inner wall is connected between the first arc segment inner all and the oblique line segment inner wall, and a second horizontal segment inner wall is connected between the second arc segment inner wall and the second linear segment inner wall; the outer wall ofthe annular shield ring body comprises a first linear segment outer wall, an oblique line segment outer wall and a second linear segment outer wall which are sequentially distributed from top to bottom. The novel energy internal combustion engine shield ring is simple in structure, high in precision, good in dustproof effect and long in service life and saves cost.

Description

technical field [0001] This application relates to the field of high-reliability, long-life sealing products, and in particular to a shroud ring for a new type of energy internal combustion engine. Background technique [0002] An internal combustion engine is a kind of power machinery, which is a heat engine that directly converts the heat energy released by burning fuel inside the machine into power. Internal combustion engines in a broad sense include not only reciprocating piston internal combustion engines, rotary piston engines and free piston engines, but also rotary impeller gas turbines, jet engines, etc., but internal combustion engines generally refer to piston internal combustion engines. Piston type internal combustion engine is the most common with reciprocating piston type. The piston internal combustion engine mixes fuel and air and burns it in its cylinder, and the heat energy released makes the cylinder generate high-temperature and high-pressure gas. The...
