Abstract
The utility model discloses a piston ring, which comprises a ring body, wherein an opening is arranged in the ring body, the ring body is formed by an upper ring and a lower ring which are fixedly connected, the upper ring and the lower ring are respectively provided with a corresponding upper groove and a corresponding lower groove, the upper groove and the lower groove are opposite, a filling cavity is formed between the upper groove and the lower groove, and rubber is filled in the filling cavity; two ends of the opening in the ring body are respectively clamped with butted nylon joints. The piston ring is simple in structure, the piston ring is formed by fixedly connecting the upper ring and the lower ring, and the filling rubber is arranged on ring walls, so that the abrasion on the wall of a cast iron ring is reduced, and the joints are convenient for open butt joint, so that the sealing property is good.
Description
Technical field
