Definitions

  • This invention relates to a vent damper for automatically regulating an airing aperture in dependence of varying condition of air humidity, particularly for the purpose of maintaining a desired degree of humidity 5 in a room.
  • a similar arrangement is likely to be used straight away in connection.with a damper that controls a venting aperture or port from a room, and instead of 35 the diaphragm another humidity sensitive member may be used, for instance a block of hygroscopic wood as is known from various air moistening devices.
  • the damper plate may appropriately in a manner known per se, cf. US " patent No. 976,150, be a laminate comprising a humidity sensitive material, suitably a wood veneer, and a relatively humidity insensitive reinforcing sheet.
  • This sheet may not only improve the mechanical strength of the damper but it may also cause it to be preloaded to a certain degree against its closing position.
  • the humidity sensitive material may by heat insulation be protected against vapour condensation. In this way it may be ensured that the humidity content of the material under all circumstances comply with the state of humidity of the air in the room.
  • Fig. 1 illustrates the damper, viewed from the inside (the side towards the room) and in an open posi ⁇ tion
  • 5 Fig. 2 is a section on a larger scale along line II-II in Fig. 1.
  • Fig. 1 illustrates a rectangular frame 1 adapted to be installed in a venting or airing aperture in a wall, not shown, while 2 is a damper plate which at its 10 upper edge is hingedly suspended in the frame and at its lower edge may be provided with lateral pins 3 which are displaceable in guiding grooves in the lateral pieces of the frame.
  • the damper 2 consists mainly in a thin wooden 15 sheet 4 that is plane when dry.
  • the surface of said wooden sheet facing the air in the room is uncovered while its opposite side is covered ' by a heat insulation 5, a reinforcing or foil sheet, such as a thin metal sheet 6, Fig. 1, being appropriately inserted between 20 the two layers 4 and 5.
  • the bare side of the wooden sheet may possibly be provided with milled groves for increasing the area of the surface so that it particularly quickly reacts on variations in the " humidity content of the air in the room.
  • Another pos- 25 sibility of accelerating the reaction of the wooden sheet consists in subjecting it to a chemical treatment in order to washing out lignin and other substances retarding the absorbing of and giving off humidity.
  • An inverted arrangement is also imaginable, i.e.
  • a humidity sensing member such as a wooden sheet which due to humidifying changes its shape from plane to curved state or from less curved to more curved shape.

Abstract

Une plaque de régulateur de tirage (2) pour la commande d'une ouverture d'évent comprend un organe (4) qui, lors de variations de l'humidité, présente une tendance à gondoler et se redresser, modifiant ainsi la surface de passage libre de l'ouverture.
