Valve oil seal assembly

A valve oil seal assembly belongs to the technical field of engines. The press-fitting tool is used for solving the problem that a press-fitting tool easily causes damage to fluororubber wrapping the upper end of an outer framework during manual press-fitting of a valve oil seal assembly. The outer framework is in an annular groove shape, the upper end of the outer framework is of a straight opening structure with an outer edge portion, the rubber body is wrapped in the outer framework, the upper end face of the outer framework is a framework face and is exposed out of the rubber body, the framework face of the outer framework is matched with a press-fitting face of the press-fitting tool, and the spring is installed on the rubber body. And the framework surface of the outer framework is a plane. A protruding gentle slope part is arranged at the lower end of the outer edge part of the outer framework and used for supporting the outer edge part. According to the valve oil seal assembly with the structure, when
