<p>A coupling bar (14) passes through a sleeve (16). The sleeve engages with an outer thread (18) into a threaded sleeve (20), which is fastened to the housing cover (12). A screw movement displaces the bar in axial direction (z). A stop (22) on the free end of the coupling bar engages on the end face (26) of the sleeve away from the valve body. The bar consists of a threaded part, and the stop has an internal thread. The position of the stop on the bar is varied by a screw movement. The stop part has a slide coating (24). <IMAGE></p> |
