<p>The invention relates to a float valve (3) for container filling systems, especially for electrical traction battery filling systems, comprising a valve housing (10) that accommodates a valve chamber (11) and a valve head (31), the valve chamber being provided with a filling medium supply inlet (16) and an outlet (17) leading to a container, the valve head (31) being connected to the float via a stem and a float rod (35, 36, 37) and being movably disposed in a valve chamber (11) to open the inlet and the outlet (16, 17) and shut off the outlet (17). To guarantee quick closing action also with low liquid pressures and to prevent dripping in the closed position it is proposed according to the invention that the filling medium be introduced first in a distribution chamber from where it flows into the valve chamber in a manner that it enters the valve chamber in the bottom area of the latter along the entire surface of the side walls and flows uniformily through the valve chamber. The valve head (31) rests in a recess (13) in the bottom of the valve chamber (11) and is for the most part outside the flow during the filling process. Only when it is lifted out of the recess (13) by the float, the valve head (31) is pushed into the closing position by the flow forces.</p> |
