Abstract

The utility model relates to an air ring, comprising a piston body in which an air ring groove and an oil ring groove are arranged. The end of the piston body is provided with three gas pressurizing holes, the inner side of the air ring groove is a pressurizing inner ring with an inner trough, pressurizing rings are engaged and overlapped in an open groove shape, and the outside of the air ring groove is an outer ring with no gap overlapping. The utility model has the advantages that structure is simple, cost is few, energy consumption is lowered, efficacy is enhanced, and use period is extended.

Description

A kind of compression ring

The utility model relates to the piston in a kind of internal-combustion engine, especially a kind of compression ring.

Usually the piston structure in the internal-combustion engine is made of with oil ring several roads compression ring, there is problems such as complex structure, cost height, serious wear, poor air-tightness, useful horsepower are low.Though, has developed a kind of piston of one compression ring in recent years, but still do not solved the fundamental issue of quick abrasion, gas leakage, leakage of oil poor air-tightness, thereby the popularization of failing is so far come into operation.

The purpose of this utility model is the deficiency that exists at prior art and a kind of improved compression ring will be provided, and has reduced wearing and tearing, has strengthened sealing, have power consumption less, effect height, pollution-free, life cycle is long, cost is low usefulness.

The purpose of this utility model is achieved in that a kind of compression ring, include a piston only, be provided with a compression and an oil ring groove in the body, the end that it is characterized in that piston only is provided with three gases and leads to pressurized hole in the compression, the inboard of compression is the interior ring of the supercharging of groove in having, the supercharging ring is open recess shape seaming overlap joint, and the outside is the outer shroud of seamless overlap joint.Its working principle: the pressurized gas that produce when the firing chamber blast enter in the compression by three pores, head on interior groove and swollen rising, and hoop moves outward in forcing, outer shroud is pressurizeed, impel outer shroud to be close to casing wall, reach good sealing, have the usefulness of a ring dual-purpose of going up envelope gas, following frizing.

The utility model is reasonable in design, simple in structure, cost is low, has alleviated weight, and good seal performance reduces wear, and has improved effect, has reduced energy consumption, and is applied widely, has use value.

Below in conjunction with drawings and Examples in detail the utility model is described in detail.
