Abstract
A valve assembly controlled by a float permits pressure-free feed of a fluid into a pipeline system, the valve being assigned in operative relationship with a channel which is arranged in the base of the tank containing the float, the channel extending laterally to the normal axis of the tank. The valve is designed as a dual valve with two valve members arranged on a valve rod guided in the direction of the axis of the tank and the channel is defined through a pair of apertures lying opposite each other in the direction of the axis of the tank with valve seats being located about the apertures, the valve members arranged on the valve rod operating to engage and disengage the valve seats to open and close the apertures.
