ABSTRACT:
A vessel mouth gasket unit is fitted around the outer periphery of a valve body which is internally formed with a filled liquid passage. A first gasket having a smaller diameter and a second gasket having a larger diameter is mounted on the lower surface of the unit. The filling valve is made up of a liquid valve opening and closing air cylinder which opens and closes a liquid valve8disposed in the filled liquid passage, and a vessel mouth gasket auxiliary air cylinder which urges the unit downward. The valve body has an outer diameter which is greater than the aperture diameter of a bottle-like first type vessel and less than the aperture diameter of a second type vessel having a larger aperture. The operating pressure of the auxiliary air cylinder is controllable and the filling operation takes place by urging the gasket against the first vessel with a low load and by urging the gasket against the second type vessel with a high load. The filling valve enables a combined use for filling the bottle-like first type vessel B and the second type vessel without requiring a replacement of parts.
