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.
