<p>Two bolt couplings (30, 50) which are arranged at either end of a coupling rod (32) each have an external joint head (34), which has a hollow chamber (36), open at least in an axial direction, together with a diametral hole (38), and an internal joint head (40) which is arranged in the hollow chamber (36) and also has a diametral hole (42). Extending through these two holes (38, 42) is a joint bolt (44) which is fixed to the external joint head (34) by a bolt fastening. For this purpose the joint bolt (44) has two ends (46) protruding radially from the external joint head (34), each with a notch (48) running across the longitudinal direction of the joint bolt (44). The bolt fastening is formed by a helical spring (28), which is supported at one end in the two notches (48) in the joint bolt (44) and at its other end on a shoulder (24; 54). The latter is preferably formed on a face seal (14) which seals the external joint head (34) against a housing section (10). …<IMAGE>… </p> |
