ABSTRACT:
Valve comprising a valve stem and a valve disc. The peripheral edge of the valve disc in the closed position comes to rest in a sealing manner against the valve seat of the corresponding valve housing. Between this sealing peripheral edge and the valve stem the valve disc is partially made of elastically yielding material. The position of the valve stem guide is such that it is 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 devices 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 example, juice packs can be avoided.
