    • At a ventilation plant possessing roof mounted down blow pipes (2) within which an in non-step-wise manner variable ventilation fan (8, 10) is arranged, the lower spreading nozzle is formed of an in upwards direction spring biased horizontal valve plate (14) which is urging to close the exit mouth of the down blow pipe (2). During operation of the ventilator fan (8, 10) the valve plate (14) is pressure influenced downwards depending upon the volume speed of the air whereby a ring shaped nozzle (26) between the valve plate (14) and an overlaying projecting rim (12) of the pipe exit mouth is formed. As the ring shaped nozzle (26) width automatically adjusts itself according to the volume speed of the air this feature can be utilised to safeguard that the radiation speed of the air from the nozzle remains approximately constant, independent of the volume speed, in which way an efficient spreading of the air during different operation conditions can be safe guarded in an extremely simple way.

    • A ventilation device (1) is provided for location at the outer edge of a window frame (52) and comprises side members (5A) defining inlet and outlet portions. The members (5A) provide opposing sockets (13B) to receive plates (4) completing a closed duct in the device for air flow, the width of this device (1) being varied by providing plates (4) of different width. The ends of the duct include closure assemblies (17), and the side members (5A) preferably comprise exactly similar structures. Weather members (6) are fitted to the side members by releasable fastening means (7, 8). In an alternative embodiment (Fig. 4), the side members are dissimilar, one integrally carrying the plates (37) while the other includes the socket (35) for the plates.

    • The present invention relates to a valve device (1) for a ventilation installation. The valve device (1) comprises a vent surface (4) that is equipped with a plurality of vent apertures (5) and a slide valve (6) comprising a slide valve plate (7) equipped with a plurality of slide valve apertures (8). The valve plate formed such that it can be varied between taking a first position (I) at which the vent apertures (5) are covered by the slide valve plate (7), and taking a second position (II) at which at least some vent apertures (5) have surfaces that overlap with some slide valve apertures (8) such that an air flow is permitted through the valve device (1). The valve device (1) is designed such that when the slide valve plate (7) is positioned on that side of the vent surface (4) that normally has a relatively higher pressure, the high pressure side (9), than the other side, the low pressure side (10). The slide valve plate (7) is formed such that the force from the pressure difference between the high pressure side (9) and the low pressure side (10) is sufficient to retain the slide valve plate in its place at the vent surface (4) when it is in the first, closed position (I).
