The invention is a device for storing and feeding out flowing material from a container particular to a valve device. The valve device of the invention comprises a housing (1), which sits on a shaft (4) and can be turned, and a rotor (5), which is equipped with a vent hole (6). The valve device is unique in that that housing (1) is equipped with ring-shaped and axial grooves (7 and 8, respectively) in which sit elastic, hermetically sealed hoses (9) that are connected to a system supplying compressed gas via channels (10, 11, 12, 13) and a cavity (A). The cavity (A) contains a blade (14) rigidly fixed to the shaft (4) that alternately seals off the channels (12 and 13).<IMAGE> |
