Embodiment Construction

[0023] FIG. 1 illustrates a simplified cross-section of a glazing comprising, in an example embodiment, two panes of glass surrounding a gap 2 . Multiple glazing can also be used in this location. The gap 2 also has a plurality of openings 3 for introducing purge gas 5 . On the opposite side a number of additional openings 4 are usually provided to divert the purge gas in order to obtain a uniform flow through the gap.

[0024] Such glazing is used in motor vehicles and aircraft which are subject to special climatic conditions in operation. Such glazings with two or more panes are known in particular in aircraft. The glass panes in the glazing are thus provided with a transparent coating on the side facing the gap 2, the transmittance of which can be varied by varying the electrical or electrochemical parameters. In particular, coatings are known whose transmittance changes as a function of the hydrogen content of the air with which the coating comes into contact.

Abstract

The invention relates to a window glazing (1) comprising at least two window panes with an intermediate ventilated space (2) arranged therebetween, wherein at least one window pane is provided with a layer which is arranged on the interior side thereof and whose transmission is controllable. More specifically, said invention relates to a multilayer glazing comprising corresponding intermediate spaces (2) in which a sweeping gas (5) circulates, wherein said sweeping gas (5) consists of a mixture of air (8) and other gaseous components in which the sweeping gas content is adjustable.

Description

technical field [0001] The invention relates to a window glass, which comprises at least two glass plates with ventilation gaps, wherein at least one glass plate is provided with a layer with controllable transmittance on the inner side. Background technique [0002] GB640,554 discloses an interior ventilation glazing for aircraft. Such glazing consists of two panes which are mounted at a distance from one another and consist of glass or plastic. The resulting gap is purged with dry air so that the double glass pane remains transparent in whatever temperature conditions it encounters during operation. [0003] EP 0 338 876 B1 discloses an electrochrome glazing with variable transparency consisting of two glass panes coated on the inside with a layer of electrochrome material. However, such glazing does not have ventilation gaps. [0004] Galvanic coatings for glass panels have been known for quite some time. An example of such a coating on a glass plate is described in U...
