A foaming device, capable of generating foam by mixing a volume of air with a quantity of liquid, optionally connected to a tank of the liquid and provided with valves for controlling the flow of air and liquid, comprises an air chamber enclosed in a resiliently deformable diaphragm, and a liquid chamber. The diaphragm is shaped in such a way as to produce an increasing rate of flow of expelled air during deformation by an air piston.
