Abstract
The utility model relates to a piston gaseous ring with concave-convex cut. The piston gaseous ring with concave-convex cut is characterized in that one end of the cut of a piston gaseous ring (1) is provided with a bump (2); the other end of the cut of the piston gaseous ring (1) is provided with a groove (3) corresponding to the bump (2). The utility model is suitable for reciprocating piston engine. The utility model has the advantages of simple structure, good sealing performance, easy manufacturing, and easy installation.
Description
Technical field
The utility model relates to engine fittings, is specifically related to the concavo-convex piston gas ring of a kind of otch.
Back of the body amount technology
Traditional piston gas ring is the monocycle that has straight cut, is contained on the piston with after cylinder body cooperates, though the contact of otch two ends, but still have straight-through gas leakage gap.In order to strengthen sealing to cylinder body, this piston gas ring in 2-3 road is housed on piston usually, and otch is staggered mutually, form the sealing configuration of " labyrinth " formula.The sealing configuration of this throttle type working principle, though the effect of certain enhanced leaktightness is arranged, but still have the defective of leakage gas.Particularly in use, each piston gas ring otch can occur and align mutually, cause the phenomenon of short circuit gas leakage that the significant sealing affection variation takes place.In order to improve the sealability of piston gas ring, people have designed the main ring of band seal plate and the built-up piston compression ring of superimposed inner loop formation on main ring, and the otch of main ring and inner loop is staggered mutually, to strengthen sealability.Because being connected to bonding or pegging graft of seal plate and main ring, seal plate comes off easily in the use, thereby poor reliability, and structure is complicated, makes and install all inconveniences.
Summary of the invention
The purpose of this utility model provides the concavo-convex piston gas ring of a kind of otch, its simple in structure, good airproof performance, and make easily and install.
The concavo-convex piston gas ring of a kind of otch described in the utility model, an end that it is characterized in that piston gas ring (1) otch be a projection (2), the other end for the groove (3) of projection (2) corresponding matching.The straight cut that the utility model will have piston gas ring now changes an end into be projection, the other end for the groove of projection corresponding matching, when in the annular groove that is contained in piston crown with after cylinder sleeve cooperates, the projection of piston gas ring otch one end and the groove fit of the other end otch, the sealing configuration of " labyrinth " formula of formation, thus sealability improved.The projection of piston gas ring cut end and groove can machine shapings on wire cutting machine tool, to guarantee the quality of fit of projection and groove.This piston gas ring has still kept the overall structure of existing piston gas ring, the problem that does not exist fixing difficulty of seal plate and seal plate to come off, and make easily and install.
The utility model is compared with existing vertical cut piston gas ring and built-up piston compression ring, has simple in structure, good airproof performance, the advantage of making easily and installing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1, an end that piston gas ring 1 blank is processed into otch on wire cutting machine tool is that the other end of projection 2, otch is that groove 3 gets final product.During use, piston gas ring 1 is contained in the annular groove of piston crown, and the groove 3 of the projection 2 that makes otch one end and the otch the other end cooperatively interacts and gets final product.Can adorn the concavo-convex piston gas ring of this otch in one to three road at piston crown, also can adorn the concavo-convex existing straight cut piston gas ring of piston gas ring and one to two road or other the improved piston gas ring of this otch together.
Claims (1)
1, the concavo-convex piston gas ring of a kind of otch, an end that it is characterized in that piston gas ring (1) otch be a projection (2), the other end for the groove (3) of projection (2) corresponding matching.
