Definitions

  • annular vanes in the form of hollow cylinders having at least the forward part thereof disposed with their common longitudinal axis at an acute angle to the plane of the front plate so that when the plate is rotated, the flow of air may be adjusted in direction.
  • a damper is provided in the duct to regulate the volume of the air flow therethrough.
  • the present invention relates to a distributor or dilfusor comprising a circular front plate with a coaxial circular opening therein merging into a sleeve adapted to be inserted into a mounting frame in the outlet of a supply duct for conditioned air, and more particularly to a distributor comprising a plurality of annular concentric vanes within said opening.
  • the present invention has as its primary object the elimination of the previous inconveniences of time-consuming changes and adjustments needed for such re-adjustment, by means of a novel, simple, and inexpensively constructed air distributor.
  • an air distributor according to the present invention is characterized by a plurality of annular vanes having at least the forward part of each facing the plane of the front plate in the form of a hollow cylinder inclined to the plane of the front plate, the common longitudinal axis of said inclined cylinders of the several vanes forming an acute angle with the plane of the front plate. It was found that an air distributor according to the invention also provides the advantages of a low-pressure drop and a low inherent noise, which makes it particularly well adapted for use in dwelling areas.
  • FIG. 1 is a cross section through an air distributor according to the invention partially displaced forward-1y in its mounting frame;
  • FIG. 2 is a view of the air distributor as seen from the line 22. of FIG. 1.
  • the air distributor comprises a front plate 1, which in the illustrated embodiment, is provided with an inturned outer edge 1a and a circular opening 2, which merges into a rearwardly projecting sleeve 3 adapted to be inserted into a mounting frame 8 surrounding the outlet of a supply duct 9 for conditioned air.
  • a plurality of annular concentric vanes 4 are supported and mutually fixed by stays 5.
  • the external parts 4a of the vanes which in the present instance, terminate in the plane of the front plate, are in the form of hollow cylinders inclined to the plane of the front plate 1, while the internal or rearward parts 4b, -i.e., the parts facing away from the front plate, are in the form of hollow cylinders oriented perpendicularly to the front plate '1.
  • the cylindrical parts 4a have a common axis which intersects the plane of the front plate 1 at the center of the opening, and the cylindrical parts 412 have a second common axis perpendicular to said plane and offset from said center.
  • the vanes may also have the same inclination along their entire length.
  • spring elements 6 are pivoted on two oppositely-extended portions 3a of the sleeve 3, said portions as shown being preferably stiffened by brackets 31) projecting rearwardly from the stays 5.
  • the spring elements 6 engage with their free ends in an annular groove 10 in the mounting frame and pass an unstable intermediate position when the air distributor is being pressed-in, as is previously described in Swedish Patent Specification 157,746.
  • the groove and spring elements also serve as a guide for the air distributor when the latter (preferably pulled-out somewhat as shown in FIG. 1), is rotatably displaced in the mounting frame for revolving the common axis of the parts 4a to effect the desired change in the outflow direction of the air.
  • an air distributor according to the invention irrespective of its mounting in a wall or ceiling, can always insure draftfree supply of pre-conditioned outside air for dwelling areas of various size and shape.
  • An air distributor for insertion into a mounting frame surrounding an outlet for conditioned ai-r, said distributor comprising a circular front plate adapted to cover said outlet and having a circular opening therein, a sleeve merging into said opening and projecting rearwardly therefrom to engage in said frame, and a plurality of annular concentric vanes mounted in said opening, the improvement wherein the forward part of each of the annular vanes facing the plane of the front plate is in the form of a hollow cylinder, inclined to the plane of the front plate, said forward parts of the annular vanes having a common longitudinal axis disposed at an acute angle with the plane of the front plate and intersecting said plane at the center of the opening to direct the conditioned air outwardly from said outlet in the direction of said common axis with a low pressure drop and low inherent noise; and
  • each vane is in the form of a hollow cylinder, said rearward parts having a second common axis perpendicular to the plane of the front plate and offset from the center of said opening.
  • An air distributor according to claim 1 including means mounting said distributor in the frame for rotary displacement about the center of said opening to afiord corresponding revolution of said first common axis.
