| description | The invention relates to hydraulic oil cylinders, in particular to an ultra-high pressure sealed structure oil cylinder. The sealing problems of an ultra-high pressure oil cylinder or an oil cylinderwith large pressure fluctuations are solved. The ultra-high pressure sealed structure oil cylinder is composed of a cylinder body assembly and a piston rod assembly. The piston rod assembly is composed of a piston rod and a piston. The piston divides the internal space of the oil cylinder into a rod cavity and a rodless cavity. Valve core holes distributed symmetrically are formed in the outer round end surface of the rodless cavity side of the piston, wherein the valve core holes penetrates through the rod cavity. A left cone valve core and a right cone valve core are installed in the valve core holes, and the cone valve surfaces are compressed by springs. A through hole penetrating through the axis is formed in the bottom of a piston combined seal groove, the through hole is connected tothe two symmetrically dis |
