A device is described, which is intended for the dosed diffusion of gases in liquids and which is used especially for small-scale application in the field of aquaria. The device consists essentially of a diffusor which can be filled with gas via an inlet device and round which liquid circulates and which is open in its lower region and is filled via an automatically regulating pressure-regulating valve.

A device for dosed diffusion of gases in liquids, particularly for application in the field of aquaria, consisting of a hollow body diffusor, a gas inlet at the upper portion of said diffusor, said inlet connected to an automatically regulating pressure-regulating valve, said valve blocked on the supply-pressure side by a valve smaller than said pressure-regulating valve operable by means of an actuating member subjected to the regulating pressure and to an adjustable prestress, said smaller valve consisting of a valve head loaded by means of a compression spring and axially movable against a sealing ring, said valve head lifted out of its leak-tight seat by means of a tappet, one end of said tappet directed to said valve head, a mushroom-shaped thrust member mounted on the opposite end of and movable with said tappet, said thrust member resting on an elastic disc-shaped diaphragm shutting off in a leak-tight manner the regulating-pressure region of said pressure-regulating valve.
