Abrégé

A vibrating device comprises a chamber (4) inside which a shaft (13) is mounted. At least one tubular member (23) is arranged in the chamber (4) around the shaft (13) and is free to rotate with respect to the shaft (13). The shaft (13) has a groove (16) in which a vane (20) is received. The shaft (13) further has an arrangement of ducts (15, 19) for feeding a pressurised fluid towards the vane (20) so as to move the vane (20) from a retracted position (PR), in which the vane (20) is housed in the groove (16), to an extended position (PE), in which the vane (20) protrudes from the shaft (13) to come into contact with the tubular member (23). The vibrating device (39) has a contact surface (40) and the vibrating device (39) is intended to be positioned in contact with an object at the contact surface in order to vibrate the object. The shaft (13) is mounted in a fixed position in the chamber (4), so that a longitudinal central plane (P1) of the groove (16) forms an angle (A) comprised between 20° and 25° with a plane (P2) perpendicular to the contact surface (40).

An aeration apparatus to ease the emptying of a mass of powdered material from any kind of container. The apparatus comprises a vibrating membrane coupled to a device for pulling and fastening it to the container wall, so that said membrane adheres to the inner surface of the container wall. The apparatus is characterized in that the inner surface of membrane has a number of grooves shaped as radial recesses formed only on the lower half of the inner surface of the membrane itself. Each radial section of any radial recess is advantageously venturi-shaped.
