Edge and lower edge are provided with described locating ring, upper edge and lower edge are respectively placed in U-type groove and open Above and below mouthful.
Otch is offered on described piston-ring packing one, piston-ring packing two offers openning, During composition piston-ring packing, otch and openning differ 180 degree circular arc, and opening is in both centers Between.
Described lower convex platform is identical with the height of convex platform and half that be U-type groove width.
Described lower convex platform is identical with the width of convex platform and depth of with U-type groove is identical.
The width of described lower convex platform and convex platform is piston-ring packing one and piston-ring packing two is wide The half of degree, the height of lower convex platform and convex platform is piston-ring packing one and piston-ring packing two is thick The half of degree.
Described locating ring is steel loop, and the thickness of locating ring is piston-ring packing one and piston-ring packing The twice of two thickness.
Technique effect of the present utility model:The bicyclic superposition knot being constituted using two piston-ring packings Structure, is then inserted into the connected mode of U-type groove by boss, in the piston ring of fuel engines It can be ensured that the opening of piston-ring packing one and piston-ring packing two is wrong during rotary motion in groove Open, define reliably hermetically sealed, two panels piston is connected using the locating ring with U-type groove Ring assemblies, effectively overcome the defect such as various motions in piston ring motor process, improve work The reliability of plug ring motion, thus improving fuel engines power, reducing oil consumption and reduce discharge Pollution.

Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further illustrated:
As shown in Figures 1 to 7, a kind of U-type groove steel loop positioning piston ring assembly, its feature exists In:Including locating ring 1 and piston ring 2, described locating ring 1 offers opening 11, positioning U-type groove 12 is offered on the outer rim of ring 1, described piston ring 2 includes equivalently-sized piston Ring assemblies 1 and piston-ring packing 2 22, convex under the inner edge setting of piston-ring packing 1 Platform 211, the inner edge setting convex platform 221 of piston-ring packing 2 22, piston-ring packing 1 It is stacked together with piston-ring packing 2 22 thus being close to lower convex platform 211 and convex platform 221 Together and be inserted in U-type groove 12 and form piston-ring packing.
Be provided with along 13 and lower edge 14 on described locating ring 1, on along 13 and 14 points of lower edge It is not placed in above and below U-type groove 12 opening.
Otch 212 is offered on described piston-ring packing 1, piston-ring packing 2 22 is opened It is provided with openning 222, during composition piston-ring packing, otch 212 and openning 222 differ 180 degree Circular arc, opening 11 is in both middles.
Described lower convex platform 211 is identical with the height of convex platform 221 and is U-type groove 12 width Half.
Described lower convex platform 211 is identical with the width of convex platform 221 and depth with U-type groove 12 Identical.
The width of described lower convex platform 211 and convex platform 221 is piston-ring packing 1 and piston The half of ring assemblies 2 22 width, the height of lower convex platform 211 and convex platform 221 is piston ring Assembly 1 and the half of piston-ring packing 2 22 thickness.
