Abstract
The utility model discloses a piston ring which comprises a ring body, and an open is provided on the ring body; one end of the opening of the ring body presents a step-like shape, and the other end of the opening shows the inverted step-like shape, and the two step-like shapes combine together. The utility model has the advantages of that: the structure is simple, two step-like shape structures are provided at the opening of the ring body. When the piston ring body is worn, the structure can get the self-compensation and prolong the service time of the piston ring body, decrease the maintenance fee, save the fuel oil greatly, control the exhaust emission and be favor to the environmental protection.
Description
Technical field
The utility model relates to the technical field of cylinder-piston assembly, more particularly relates to a kind of piston ring that uses on the cylinder piston.
Background technique
At present, three groups of piston rings all are installed on the cylinder piston of explosive motor, wherein going up two groups of piston rings is that compression ring is mainly used to mixed gas in the blanket gas cylinder body, this piston ring is between piston and cylinder body, when internal combustion engine, piston ring will be made high-speed motion up and down along with piston, because the action of high temperature that produces when being subjected to frictional force and motion, after using a period of time, piston ring will be worn, again owing to just be provided with opening on itself ring body of the new piston ring of installing, this plane of the opening is vertical with plane, ring body place, under the situation that piston ring is worn, it is big that the gap of this opening will constantly become, cause the tightness of cylinder to reduce, the output power of cylinder also can constantly reduce simultaneously, the fuel consumption of automobile will constantly strengthen, the exhaust emissions of automobile will severe overweight, thereby polluted atmosphere, be unfavorable for environmental protection, after this opened gap is above the scope that allows, just can not continue to use, the piston ring that can only more renew or entire cylinder keeped in repair, thus the maintenance expenses of cylinder increased.
The model utility content
The purpose of this utility model provides a kind of simple in structure in order to solve the problems of the technologies described above exactly, and a kind of piston ring of the automatic compensating piston ring body opened gap of energy.
The technical solution that the utility model adopts in order to solve the problems of the technologies described above is as follows:
A kind of piston ring comprises ring body, and this ring body is provided with opening, and an end setting of described ring body opening is step-like, and the other end setting of opening is inverted step-like, opening two step-like match to take put together.
Described opening step-like L-shaped.
The step-like shoulder height of described opening is half of ring body thickness.
The step-like step circumferential lengths of described opening is 2-4 a times of shoulder height.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: simple in structure, the ring body opening setting of piston ring is two step-like structures of putting together of taking that match, can be under the situation that the piston ring body is worn, ring body self can play the effect of automatic compensation, thereby prolonged the working life of piston ring body greatly, reduced the maintenance expenses of cylinder, can also save fuel resource greatly, control toxic emission effectively, helped environmental protection.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of looking up of Fig. 1.
Embodiment
By illustrated in figures 1 and 2, a kind of piston ring, comprise ring body 1, this ring body 1 is provided with opening 2, one end setting of described ring body opening 2 is step-like 3, the other end setting of opening 2 is inverted step-like 4, two step-like 3 of opening 2 places, 4 match takes and puts together, these are step-like 3 years old, 4 can be made of the two-stage step, also can constitute by multistage step, size on piston ring is decided, usually with step-like 3 of ring body opening 2 places, 4 are arranged to two-stage is advisable, and makes step-like 3 of ring body opening 2 places, 4 is all L-shaped, and they are step-like 3 years old, 4 shoulder height is half of ring body 1 thickness, step-like 3,4 step circumferential lengths is that the 2-4 of shoulder height doubly is advisable, and this kind structure not only helps processing, guaranteed greatly that also piston is at work to the requirement of piston ring bulk strength.The compression ring that the structure of this piston ring both can be used as on the piston uses, and the oil ring that also can be used as on the piston uses, and can also be applicable on the cylinder piston of various model air compressors.
Claims (4)
1, a kind of piston ring comprises ring body, and this ring body is provided with opening, it is characterized in that: an end setting of described ring body opening is step-like, and the other end setting of opening is inverted step-like, opening two step-like match to take put together.
2, a kind of piston ring according to claim 1 is characterized in that: described opening step-like L-shaped.
