Abstract
A kind of non-interval piston compression ring comprising ring body, has an opening and forms two terminations on the ring body, a termination fixedly has fixture block, and another termination has breach, cooperates stacked between fixture block and the breach.This non-interval piston compression ring good seal performance can reduce oil consumption.
Description
Technical field
The utility model relates to a kind of piston ring, relates in particular to the non-interval piston compression ring that uses on the piston in a kind of internal-combustion engine.
Background technique
At present, the piston gas ring of installing in the compression on the piston of internal-combustion engine is a kind of Sealing, contacts with cylinder sleeve by it to make cylinder keep sealing.When piston was reciprocating in cylinder, piston gas ring moved in cylinder with piston, thereby produced sliding friction between piston gas ring and the cylinder sleeve and cause wearing and tearing.Traditional piston gas ring has an opening, form two terminations, this piston gas ring can't keep good sealing at opening, it is serious more to wear and tear, opening is just big more, the wearing and tearing of internal combustion engine is of long duration later piston gas ring cause inner cylinder pressure to descend, so the outputting power of internal-combustion engine descends, oil consumption is risen.Generally, in order to strengthen the tightness in the cylinder, take to use the method for a plurality of piston gas rings, still, after using a plurality of piston gas rings, the surface friction drag between piston gas ring and the cylinder sleeve increases, thereby causes oil consumption to increase, and can not tackle the problem at its root.Therefore, improving the sealing of piston gas ring, is the effective means that effectively improves internal-combustion engine life-span, minimizing oil consumption, keeps the outputting power of internal-combustion engine.
Summary of the invention
The utility model purpose provides a kind of non-interval piston compression ring of good seal performance.
For achieving the above object, the technical solution adopted in the utility model is: a kind of non-interval piston compression ring, comprising ring body, have an opening on the ring body and form two terminations, its characteristics are that a termination has fixture block, another termination has breach, cooperates stacked between fixture block and the breach.
Owing to adopted above-mentioned fixture block to cooperate stacked technological scheme with the corresponding breach in another termination with a termination of non-interval piston compression ring, make the utility model sealability better, more stable, and because fixture block and breach have a segment distance, after the utility model wearing and tearing, can also reach the better seal effect, thereby its wear-resisting property strengthens, the prolongation in working life by automatic prolongation adjustment.Use on the piston of internal-combustion engine together that this non-interval piston compression ring just can play good sealing effect, reduce the surface friction drag of piston gas ring and cylinder sleeve in to-and-fro motion, reduce oil consumption.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Embodiment 1:
A kind of non-interval piston compression ring as shown in Figure 1, comprising ring body 1, has an opening and forms 2,5, one terminations 2, two terminations and have fixture block 3 on the ring body 1, another termination 5 has breach 4, cooperates stacked between fixture block 3 and the breach 4; Cooperating stacked surface of contact between fixture block 3 and the breach 4 is that smooth flat and sealing combine; Fixture block 3 is complementary with the thickness size of corresponding breach 4; Fixture block 3 cooperates stacked surface of contact with breach 4 be the plane of inclination, and fixture block 3 is that wedge-like engagement is stacked with breach 4.
