Abstract
A connecting apparatus for the connection of a valve rod (4) to a closure member (1) of a vacuum valve, with a connecting body (12) which is arranged between a first connecting part (10) and a second connecting part (11). The connecting body (12) has a basic shape of a Steinmetz body which is formed by way of a intersection of two circular cylinders. The connecting body (12) is arranged in an intermediate space between arm projections (24, 25) of the first connecting part (10) and in an intermediate space between arm projections (26, 27) of the second connecting part (11). Corresponding bearing faces (28, 29, 30, 31) of the arm projections (24, 25, 26, 27) bear against bearing faces (13, 14, 15, 16) of the connecting body (12). The two arm projections (24, 25, 26, 27) of the respective connecting part (10, 11) approach one another towards their free ends.
