Helical spring inner stay oil ring (hereinafter referred to as the inner stay oil ring) is a new type of piston ring oil structure, in fact it is a combination of oil ring. In the cast iron oil ring cut a groove on the inner circle, the allocation of a coil spring, the elastic ring by the spring pitch and wire diameter to adjust. The spiral spring inner stay oil ring produced by our factory passed the appraisal in 1979 with the help of Shanghai Internal Combustion Engine Research Institute, Wuhan Institute of Material Protection, Shanghai Diesel Engine Factory and Shanghai Internal Combustion Engine Factory. The current annual output of 500,000, for Shanghai Diesel Engine Factory, on
