Definitions

  • a ventilator comprises a frame defining a cylindrical passage through which air is adapted to fiow.
  • a closure member is located in this passage and movable deeper into the same whereby to close the passage against flow of air, and further out of the passage to define with the wall bounding the passage annular gaps whose crosssectional area increases as the closure member moves farther out of the passage.
  • the present invention relates to a vent, and more particularly to a ventilator for use in effecting the exchange of air in rooms where the ventilator is installed.
  • vents or ventilators are distinct from fans in that they have no means for inducing the ow of air, as do the blades of a fan. In effect, they are frames which define an opening and a closure means for this opening.
  • the present invention is intended to overcome these problems and to provide an improved vent of the type under discussion.
  • a vent comprising, in combination, frame means having an inwardly directed surface bounding a cylindrical passage having spaced axial end portions and being adapted for flow of a fluid therethrough, and a owcontrolling plug member extending into one of the end portions of the passage and being movable axially of the latter between a first position closer to the other of the end portion and in which it completely closes the passage, and a plurality of second positions progressively farther spaced from the other end portion and in which the member defines with the surface respective annular gaps whose cross-sectional area increases with increased spacing of the member from the other end portion.
  • the drag of air passing therethrough is considerably reduced, thus increasing the airflow.
  • the quantity of air passing through the device can be simply and in effect continuously varied, and new air is thoroughly and intimately admixed with air present in the room if, also in accordance with my invention, the device is provided with means for imparting to the incoming air a swirling motion. Also, the adjustability of the device permits setting of the same for maximum desired airflow with minimum air turbulence in the room, even in the vicinity of the ventilator itself.
  • FIG. 1 is a front elevation of a ventilator according to the invention, installed in and through a wall;
  • FIG, 2 is a section on the line II-II of FIG. 1, with the closure member omitted;
  • FIG. 3 is a partly sectioned view, taken on the line III-III of FIG. 1.
  • the device according to my invention comprises a frame which defines a tubular seat or passage 1 of substantially elliptic crosssection.
  • the frame is installed through a wall of a room, as ⁇ best seen in FIG. 3, in which the direction of airow vfrom the outside into the room is'indicated by the arrows F.
  • the inner end portion of the passage 1 is bounded by a perimetric inner wall surface 2 which flares outwardly and axially away from the passage 1.
  • the surface 2 thus defines an extension of the passage 1.
  • FIG. 2 shows clearly that the degree of flow of the surface 2 that is the inclination of the same with reference to the longitudinal axis of the passage 1, is different at different circumferential locations. The smallest angle of inclination is to be found at the side which will face the room ceiling when the device is installed.
  • This angle is indicated in FIG. 2 as the angle a.
  • the angle ,B On the side opposite the one just discussed that is the side facing the flow of the room, the angle of inclination of the surface 2 is identified as the angle ,B which is greater than a and is assumed in this instance to approach 45.
  • the angle 'y at the sides (see FIG. 3) is still greater and is assumed to approach 60 in the present emfbodiment.
  • This configuration of the surface 2 makes it possible to position the device very close to the ceiling S of a roomthe distance l1 shown in lFIG 2 being the minimum showing from the ceiling-and assures the most advantageous air distribution in sidewise and in downward direction.
  • a closure plug member 3 Arranged in the passage 1 coaxially therewith is a closure plug member 3 of substantially paraboloid outline. Due to the configuration of the member 3, coupled with the cross-section of the passage 1, movement of the member 3 deeper into the passage 1 opposite the arrow M (see FIG. 3) will result in complete closure of the passage 1 as is readily evident from FIG. 3.
  • Movement of the member 3 in the direction of the arrow M will result in establishment of an annular gap between the head 3a of member 3 and the surface bounding the passage 1, and the cross-sectional area of this gap will fbe the greater the farther the member 3 is moved in direction of the arrow M. This, then, permits continuous variation of the cross-sectional area of such ⁇ annular gap, and therefore of the quantity of air which can pass through the device in the direction of the arrows F.
  • I further provide the outer surface of the member 3, rearwardly of the head 3a, with at least one and preferably with a plurality of radially prejecting air-guide blades 4 lwhich are helically convoluted ⁇ as seen in FIG. 3. These blades 4 will impart a swirling or twisting motion 3 to air passing through the device, so that such air will spin when entering the room and 4will thereby be assured of better admixture with air already present in the room.
  • the blades 4 also serve the purpose of guiding and centering the member 3 in the passage 1 for axial movement therewithin. Further, springs (not shown) or other means can be employed-for instance interposed between member 3 and the wall bounding the passage 1-to stabilize the member 3 and provide some frictional resistance to prevent unintentional movements of the member 3.
  • An air vent for installation in wall means separating an enclosed area from ambient space so as to exchange air between the two through the intermediary of said air vent comprising in combination, frame means for installation in said wall means and having an inwardly directed surface bounding a cylindrical passage having spaced axial end portions respectively communicating with said area and said ambient space and being adapted for liow of a iiuid therethrough; a flow-controlling plug member extending into one of said end portions of said passage and having a cross-sectional area which decreases from said one end portion of said passage so as to create a free passage portion of diverging cross-sectional area, said plug member being movable axially in said 'passage between a first position closer to the other of said end portions and in which it completely closes said passage, and a plurality of second positions progressively farther spaced from said other end portion and Nin which said member denes with said surface said free 4 passage portion whose cross-sectional area increases with increased spacing of said member from said other end portions; and fin means provided on said plu-
  • a vent as defined in claim 1, wherein said tin means also constitutes fluid-directing means operative for mparting an angular component of movement to fluid owing through said passage in axial direction of the latter.
  • said fin means comprises at least one helically convoluted blade projecting substantially radially of said passage.
