More Information
Summary:The utility model discloses an elastic lining piston ring which is provided with an upper ring body and a lower ring body which are assembled together. Compared with products of the same type, the method has the following improvements and advantages; annular hole cavities corresponding in position are formed in the inner sides of the upper ring body and the lower ring body; and elastic assembliesare arranged in the annular hole cavities. A piston ring body structure is formed by the upper ring body and the lower ring body, so that the whole piston ring has good toughness; meanwhile, the elastic nylon pad is additionally arranged on the inner wall of the piston ring and is clamped in an annular hole cavity formed in the inner side of the upper ring body and the inner side of the lower ringbody, so that on one hand, the piston ring has good elastic performance, and on the other hand, the elastic nylon pad can play a role in connecting the upper ring body and the lower ring body. The outer end face of the upper
