Embodiment Construction

[0037] Firstly, the metering device 1 comprises a valve housing 2 which is arranged on the cover plate 3 of the filling chamber. In a filling chamber, not shown, containers, especially packagings made of composite material, are filled with a liquid, for example fruit juice. The outlet 4 of the metering device 1 is aligned with the passage 5 in the cover plate 3 corresponding to its outlet cross-section. Concentrically arranged below the cover plate 3 to the outlet 4 of the metering device 1 is a cylindrical outlet opening 6 known per se. The outflow opening 6 can of course also be fixed directly on the metering device 1 .

[0038] The outflow opening 6 is functionally divided into a central outflow opening 7 and an edge outflow opening 8 surrounding the central outflow opening. Both the central outlet opening 7 and the peripheral outlet opening 8 are formed by a plurality of cylindrical, preferably cylindrical, passages 9 distributed adjacent to one another in the axial dire...

Abstract

The invention relates to a dosing device having an inlet (28) for a liquid to be delivered to a container as a dose, in particular a beverage. The device comprises a valve seat (14), a sealing element (10, 11) interacting with the valve seat and an outlet (4) for the dose of the liquid. In order to reduce foam build-up upon delivering the liquid into the container, according to the invention the sealing element can be moved to a first and a second opening position, wherein, in the second opening position, the flow cross-section area between the valve seat and the sealing element is larger than in the first opening position. In addition, the invention relates to a dosing method comprising the supplying of a liquid to a valve which is moved to a first and second opening position.

Description

technical field [0001] The invention relates to a liquid flow control device, in particular a metering device, with an inlet for, in particular dosed, liquid to be delivered, comprising a valve seat, a closure element cooperating with the valve seat and a closure for the liquid. exit. Furthermore, the invention relates to a method, in particular a metering method, for dispensing liquids. Background technique [0002] Such metering devices and metering methods are used, for example, for the rapid filling of containers, in particular packaging made of composite material (cardboard and PE coating), with liquids (milk or fruit juice). When filling with this liquid, it should be noted that foam should not be generated as much as possible. This is important because the packaging made of composite material is folded over at its upper end after filling and closed by welding. If foaming occurs, the inner surface of the edge of the upper packaging, which will then form the weld sea...
