In a method of controlling the infeed of air from an auxiliary conduit of a pneumatic conveyor installation into a tubular conveyor conduit into which compressed gas is introduced from a connecting conduit and the latter, upon a rise in pressure occurring upstream of the mouth thereof in the conveyor direction, in the conveyor conduit, is opened with a supply of air from an auxiliary conduit at high pressure, said supply of air into the conveyor conduit is interrupted in the event of pressure equalisation building up therein, by a control member which opens and closes the connecting conduit and which is guided in a path of movement which can be acted upon by at least one secondary flow of the auxiliary conduit, and a closing force is applied in a pulse-wise fashion to the control member.
