<p>Two push members (109, 110), each provided with an engagement toothing, are guided in a housing (100) and are held in engagement with a pinion (103', 103'') from opposite sides. So that the gear can be produced efficiently by the production methods customary in the construction of fittings and nevertheless has only a small cross-sectional dimension, two pinions (103', 103''), each with three teeth, are mounted at a distance one behind the other in the gear housing (100) and are held independently of one another in engagement with the push members (109, 110). The two pinions (103', 103''), rotated through half a division spacing relative to one another, are in engagement with the push members (109, 110). <IMAGE></p> |
