Abstract
The utility model belongs to the technical field of an internal combustion engine, particularly relating to a combined piston ring which is characterized in that the combined piston ring is composed of an upper piston ring body and a lower piston ring body, and bosses and openings are all arranged on the upper piston ring body and the lower piston ring body. When the utility model is installed, the boss on the upper piston ring body is clamped into the opening of the lower piston ring body, and the boss on the lower piston ring body is clamped into the opening on the upper piston ring body. The utility model has the advantages of more reasonable structure, good air tightness, service life prolonging, easy processing, low cost, etc.
Description
The utility model relates to the internal combustion engine technologies field, the compound piston ring that particularly a kind of life-span is long.
The opening of existing internal-combustion engine piston ring has the plane, also have nonplanar, in the use because wearing and tearing and the heat expansion factor cause the piston ring poor air-tightness, motor can not be worked under kilter, increased maintenance expenses again.
Advantages such as the purpose of this utility model is the deficiency that exists at existing product, designs a kind of novel compound piston ring, and it has rational in infrastructure, and air-tightness is good, and prolong working life greatly, easily processes, and manufacturing expense is low.
Technological scheme is: the technical characteristics of this compound piston ring is that it is made of upper piston ring body and lower piston ring body two-part, be equipped with boss and opening on upper piston ring body and the lower piston ring body, the upper piston ring body is buckled on the lower piston ring body during installation, boss on the upper piston ring body snaps onto the opening on the lower piston ring body, and the boss on the lower piston ring body snaps onto the opening on the upper piston ring body.Upper piston ring body and lower piston ring body are made with the rubber-like steel, and its effect is identical with existing open type piston ring body.Boss on upper piston ring body and the lower piston ring body be upper piston ring body after prevention is installed and lower piston ring body in use its relative position arbitrarily slide, cause two openings on upper piston ring body and the lower piston ring body to overlap the effect of gas leakage.The effect of two openings on upper piston ring body and the lower piston ring body all plays expansion piston ring body diameter.
In the use, the upper piston ring body is anchored on the lower piston ring body, boss on the upper piston ring body snaps onto the opening on the lower piston body, boss on the lower piston ring body also snaps onto the opening on the upper piston ring body, because piston weares and teares to cylinder body, diameter of cylinder increases in the work, then the diameter of this compound piston ring also increases by elasticity thereupon, all the time seal, so its can be effectively pre-anti-gas-leak, can prolong greatly its working life.
Advantages such as this piston ring has more reasonable structural design, and air-tightness is good, and long service life is easily processed, and cost is low, and equipment investment is little can be suitable for using on all kinds of internal-combustion engines.
Fig. 1 is embodiment master's TV structure schematic representation of upper piston ring body component of the present utility model.
Fig. 2 is embodiment master's TV structure schematic representation of lower piston ring body parts of the present utility model.
Fig. 3 is embodiment master's TV structure schematic representation of the compound piston ring after installing.
Among Fig. 1, Fig. 2, Fig. 3: 1. upper piston ring body; 2. boss; 3. opening; 4. lower piston ring body.
