Abstract

Ventilateur destine a etre place sur une feuille impermeable (3) a une certaine distance sous une toiture (6) et servant a creer une circulation depuis un espace d'air sous la feuille vers un espace d'air sous la toiture et consistant en un tuyau (10) dont la longueur qui est plus courte que la distance entre la feuille (3) et la toiture (6), et avec une bride (11) autour de son extremite, sur lequel une couche de pate resistante aux intemperies s'ecarte du tuyau sur le cote exterieur de celui-ci.Fan intended to be placed on a waterproof sheet (3) at a certain distance under a roof (6) and used to create a circulation from an air space under the sheet to an air space under the roof and consisting of a pipe (10) whose length which is shorter than the distance between the sheet (3) and the roof (6), and with a flange (11) around its end, on which a layer of weather resistant paste is away from the pipe on the outside of it.

Description

Ventilating and pressure equalizing valve.
Due to leakiness of a roof covering a watertight foil is often suspended at a distance below the roof covering when, due to internal isolation, no possibility exists for making the roof covering tight from the inside. At locations of the roof where trimmings are positioned for e.g. roof windows or chimneys, and where the passage of the air from the air layer below the foil and to the roof covering accordingly is prevented, a valve must be arranged in order to avoid condensation of water which may seep through the layers in the roof. Accordingly, the invention relates to a valve as indicated in the opening clause of the claim and the features characteristic for said valve are defined in the characterizing clause of the claim.
The valve is being mounted at the required location by adhering the valve to the upper surface of the foil and then by cutting away the covered area of the foil within the valve. Besides creating in this way circulation from the lower side of the foil to the roof covering through the leakages of which the air then can escape into the atmosphere, the valve will due to the construction and the way of arrangement thereof, effectively obstruct rainwater, which streams downwardly along the foil, where the valve is arranged. Accordingly, the water will only flow past the valve. A valve according to the invention will be explained with reference to the drawing, on which
Fig. 1 shows an embodiment of the valve, and wherein the valve shown perspectively consists of an obliquely cut weather-resistant plastic tube (10) having a collar (11 ) which at the side facing away from the tube has been provided with a weather-resistant adhesive. Fig. 2 illustrates the valve arranged in a roof covering where numbers (10-11) for the sake of easiness have been united to number (4). The valve (4) is mounted on the foil (3) below the roof covering (6), but above the isolation layer (2) membrane (7) and internal covering (1 ).
The valve may be produced in several sizes, the one here shown being suitable, seeing that more valves may be mounted according to need. For instance, two valves mounted respectively above and below a skylight, chimney of the like breach will be sufficient for maintaining the structure free of condensed water and to provide a natural pressure equalizing .

Claims

P a t e n t c l a i m.
Valve to be arranged upon a watertight foil suspended at a distance below a roof covering in order to create circulation from the air layer below the foil and to the roof covering, c h a r a c t e r i z e d in that the valve consists of a tube (10) having a length which is shorter than the distance between foil and roof covering, said tube (10) comprising around one of its ends a collar (11) which on the side facing away from the tube is provided with a layer of weather-resistant adhesive.
