Definitions

  • ABSTRACT OF THE DISCLOSURE A device for regulating the volume and direction of air flow supplied or exhausted through an opening including a substantially closed sector-shaped valve element having overlapping arcuate edge portions mounted in the opening to regulate the direction of flow.
  • a strap mounted on the frame overlaps and maintains the edge portion in the set position.
  • the present invention relates to a regulating device for supplied or exhausted room air, which consists of a connection piece having a rectangular frame having an opening arranged in a wall or ceiling, a duct section connected to the inside of the frame, and a valve body mounted in the piece.
  • regulators of this kind have been constructed, for example, as a grille with adjustable damper blades, with the aid of which the direction of the air being blown into the room can be altered.
  • a hinged flap is arranged in front of the grille, as seen in the direction of air flow. This flap is adjustable in different positions by means of a comparatively complicated and expensive control device.
  • the object of the present invention is to permit a simple setting of the volume and/or direction of air flow by means of a single element consisting of a valve body arranged in the duct section.
  • An additional object is to design the valve body so that the least possible noise occurs upon passage of air through the duct section.
  • valve body according to the invention is a closed body of sectorshaped cross section which may be adjusted angularly within the frame opening and in which the included angle is adjustable.
  • FIG. 1 shows a cross section through a regulating device according to the invention
  • FIG. 2 shows the same device seen from the front
  • FIG. 3 shows a similar device embodying the plural valves seen from the front.
  • the regulator shown in FIGS. 1 and 2 consists of a connection piece with a rectangular frame 1 surrounding an opening and a duct section 2 connected to the inside of the frame.
  • two damper blades 3 and 4 are pivotally joined along their one edge about a 3,389,649 Patented June 25, 1968 common shaft 5 and act as a throttling device.
  • the opposite edges of the blades are formed with slightly curved portions directed toward and overlapping one another to provide a substantially closed valve body of a principally sector-shaped section.
  • the radius of curvature of each overlapping edge portion is centered on the shaft.
  • the adjustments of the valve body are held by a fastener passing through the portions and anchored in a slotted strap mounted across the frame opening and having a curvature similarly centered on the shaft 5.
  • the regulator may be modified as shown in FIG. 3.
  • the duct section is divided into a number of sections by means of partitions 7.
  • each section there is a valve body 8 pivotally arranged and constructed of blades similar to the blades 3 and 4.
  • a grille is provided that is of the necessary size and in which the valve bodies which are in line with each other are arranged on the same shaft.
  • each section has a length equal to twice its width. In this way certain sections can be arranged at right angles to the sections arranged in line with each other and in double rows. For example, as shown, the end sections are arranged at right angles to the rows for the purpose of attaining a suitable diffusion from the grille.
  • connection piece can be fixed in position in the wall or ceiling in a simple manner, for example, by spring locking elements arranged at the ends of the connection piece and having recesses in which flanges fastened in the wall are designed to be engaged.
  • attachment of the frame can take place in conformity to the means shown in Swedish Patent 153,807.
  • a regulating device for supplied or exhausted ventilating air comprising a rectangular, flanged frame member adapted to be mounted in a ventilation duct opening in a wall or ceiling of a room, a duct section connected to the rear side of said frame member having a common shaft extending perpendicularly with respect to the flow direction in said duct section, and throttling means arranged in said duct section consisting of two angularlyrelated damper blades pivotally joined along their one edge about said shaft, the improvement wherein the damper blades at their opposite edges, are provided with bent, slightly curved edge portions directed towards and overlap-ping into one another so as to form a valve body having a substantially closed, sector-shaped cross section.
  • damper blades loosely receive the shaft, affording turning of the blades independently relative to each other and relative to the shaft, said shaft being stationary and fixed to the walls of the duct secion, and including means to hold the damper blades in set positions.
  • a regulating device wherein said curved edge portions have a radius of curvature centered on said common shaft, said holding means comprising a strap having a similar curvature mounted on said frame overlying said edge portions, and fasteners to anchor said edge portions to said strap.
  • a regulating device in which the duct section is divided by partitions into a number of passages, each containing a valve body formed as defined in claim 1, and in which the valve bodies are situated in line with each other land are'pivotally arrhng d oil the FOREIGN iATENTS same shaft.
