ABSTRACT:
A water replenishment plug for batteries containing a liquid electrolyte has a push-in plug housing (11) which is made complementary at the outside to an upper battery housing opening. Furthermore, a water chamber (13) is provided at the push-in plug housing (11) at the top and has a water supply opening (15) closeable by the valve (14) and at least one flow connection to the region of the push-in plug housing (11) which, after the insertion into a battery housing opening, communicates with the interior of the battery. Furthermore, at least one tube stub (16) is provided onto which a water supply hose can be placed and which stands in flow connection (17) with the valve inlet (18). A float (19) which projects out of the push-in plug housing (11) at the bottom is connected via a float rod (20) and a cross-piece (21) provided at its upper end region to the valve body (22) which has a valve stem (27) and cooperates with a valve seat (15) at the valve housing (24). In accordance with the invention the valve stem (27) is connected to the cross-piece (21), in a form-fitted and play-free manner, at least in the vertical direction.
