VALVE

摘要

Valve comprising a valve stem (6) and a valve disc (7). The peripheral edg e (8) of the valve disc in the closed position comes to-rest in a sealing mann er against the valve seat (10) of the corresponding valve housing. Between this seal- ing peripheral edge and the valve stem the valve disc is partially made of elastical- ly yielding material. The position of the valve stem guide is such that it i s possible to move the valve further in the direction of closure after the peripheral edge rests against the valve seat. This means that a vacuum can be created with the aid of the valve according to the invention. Such a vacuum can be used in filling devic es for drinks. The nozzle in this case is made of a relatively flexible material which closes when vacuum is created. In this way after-dripping of drinks in, for exam- ple, juice packs can be avoided.
