Connecting apparatus for the connection of a valve rod to a closure member of a vacuum valve

A connecting apparatus for the connection of a valve rod to a closure member of a vacuum valve, the connecting apparatus comprising

• a first connecting part which is at least one of connectable to, connected with, or configured in one piece with the valve rod,
• a second connecting part which is at least one of connectable to, connected with, or configured in one piece with the closure member,
• a connecting body arranged between the first connecting part and the second connecting part,
• the connecting body has a basic shape of a Steinmetz body which is formed by way of a intersection of two circular cylinders, said Steinmetz body including primary bearing faces formed by sections of a first cylindrical surface which surrounds a first axis and secondary bearing faces formed by sections of a second cylindrical surface which surrounds a second axis which lies at a right angle with respect to the first axis, and
• the first connecting part includes first arm projections, between which a first intermediate space lies, in which the connecting body is arranged, and the second connecting part has second arm projections, between which a second intermediate space lies, in which the connecting body is arranged, the first arm projections of the first connecting part having primary corresponding bearing faces which are formed by sections of a third cylindrical surface which surrounds the first axis and bear against the primary bearing faces of the connecting body, and the second arm projections of the second connecting part having secondary corresponding bearing faces which are formed by sections of a fourth cylindrical surface which surrounds the second axis and bear against the secondary bearing faces of the connecting body, and
• the first arm projections of the first connecting parts approach one another in sections, which adjoin free ends of the first arm projections of the first connecting part, toward the free ends of the first arm projections of the first connecting part, and the second arm projections of the second connecting part approach one another in sections, which adjoin free ends of the second arm projections of the second connecting part, toward the free ends of the second arm projections of the second connecting part.
