Zusammenfassung:	The apparatus comprises a cylindrical pipe (10) in communication with a storage container for pulverulent matter and an entry (18) for gas under pressure. The pipe (10) has at least one outlet orifice (22) and an inner liner (32) coaxial with the pipe (10) and in contact with the latter comprises an opening (34) capable, by moving the liner, of forming a smaller or larger passage with the orifice (22). The apparatus can be used to form a pneumatic stream or to control the flow rate of a pneumatic stream.
