Definitions

  • the present invention relates to a regulating device in a channel, an apparatus or a similar unit provided with treating means for a gaseous medium, for instance a heating medium, and a by-pass arranged side-by-side with said means, and regulating device being intended for simultaneous regulation of the quantity of passing medium as well as the ratio between treated and non-treated medium.
  • the invented device is characterized by in combination a damper swingably arranged at the front edge of a partition between the treating means and the by-pass and a sliding damper co-operating with said swingable damper and by its movement shielding or opening a number of flow passages arranged in a partition crossing the channel, said two dampers being operated by one and the same maneuvering means in such a manner that the area of the passages and thus the medium quantity is reduced as a larger part of the medium is caused to pass through the treating means.
  • the by-pass may suitably be dimensioned to allow a greater medium quantity to pass than that which can pass through the treating means, the swingable damper thus emphasizes the reduction of the medium quantity as a larger part of the medium is caused to pass through the treating means.
  • the two dampers may either be made to start or end their movements simultaneously or the sliding damper can be caused to start and/or end its movement in a direction towards a reduction of the medium quantity before the swingable damper has been caused to guide part of the medium through the treating means or after whole the quantity of the medium has been guided through the treating means respectively.
  • the invented device may often be used when a plurality of apparatus are connected to a common distributing duct for the medium.
  • a volume governor arranged in front of the sliding damper.
  • Such a governor may suitably be made in accordance with my patent application Serial No. 540,947, filed October 17, 1955, the partition indicated in said patent application in such a case being constituted of the above mentioned partition shielded by the sliding damper.
  • FIG. 1 shows a cross section through an apparatus, provided with the invented regulating device.
  • Fig. 2 shows a suitable embodiment of means for maneuvering the regulating dampers.
  • Fig. l 1 designates an apparatus provided with an inlet 2 for the medium.
  • a throttle 3 which throttle is turnable about an axle 4.
  • 5 designates a volume governor of a design known per se.
  • 6 designates a partition arranged across the apparatus and provided with one or more apertures. The size of the effective area of the apertures is regulated by means of a damper 7 slidably movable perpendicularly with respect to the cross section plane and guided by therails 8.
  • the apparatus may suitably be equipped with a sound trap within the apparatus, said trap being of a design known per se. In the drawing an embodiment of such a sound trap is designated 9.
  • the apparatus is divided by means of a partition 13 into a space for a treating means 12 and a by-pass 11.
  • the ratio between treated and by-passed non-treated medium is regulated by means of a damper, which damper is illustrated in the drawing in broken lines 10 in a position where the treating means is cut off, and in full lines 10 in a position where the bypass is closed.
  • the damper is swingable about an axle 10a. Said damper can, of course, also be put in any intermediate position.
  • the medium passing the treating means and/or the bypass enters a mixing chamber 14, from which it continues through the grill 15.
  • Fig. 2 16 designates a knob for the maneuvering of the regulating device.
  • the knob is fastened to shaft 17 equipped with a screw-thread made of heavy wire. This thread is arranged to engage a groove of a catching means fastened to a rod 20.
  • 21 and 22 designate likewise catching means, the upper one of which 21 being fixed and the lower one being movable and counteracted by a spring 23. These catching meansengage a lever 24 fastened to the axle 10a of the above mentioned swingable damper 10.
  • there are two catching means 25 and 27 for the movement of the sliding damper 7 which means actuate a pin 26 of a lever 28.
  • Said lever is pivoted about the axle 29, in the other end of which there is still another lever 30 which by means of a link 31 is connected with said sliding damper 7.
  • For adjustments of the throttle 3 there is a lever 35 arranged on the axle 4 of said throttle,
  • the throttle 3 is closed, the damper 10 is in the position 10 (the passage through the element 12 being fully open), and the damper 7 is in its most shielding position.
  • the throttle 3 is first fully opened, and is held in this position, the damper 7 is then gradually actuated toward a less shielding position, and the damper 10, owing to the action of the spring 23, is held in the position 10'.
  • the stop 21 engages the lever 24 to gradually move the damper 10 toward the position shown in broken lines, whereby the bypass is gradually opened.
  • a device for regulating the flow of a gaseous medium comprising means defining a channel having an inlet at one end and an outlet at the other end, partition means extending longitudinally in one portion of said channel forming a main passage and a by-pass passage connected in parallel, means in said main passage to treat the medium flowing therethrough, proportioning means at one end of said partition means to proportion the flow of medium between said passages and thereby control the ratio of between treated and non-treated medium comprising a damper movable between a first limit position directing the flow of medium entirely through said by Patented Feb. 11, 1958.
  • transverse partition disposed in another portion of said 4 terminating operation of said proportioning damper trom channel and having apertures therein forming flow pas- I sagesinseries'relatiorrto saidiparallekconnected passages;
  • a sliding damper operable between'ia'first position fully opening said flow passages-and a second 'positi'orr closing' said 'flow passages tot-thereby regulate the total flow of' medium' through said channel; a'common operator for said dampers to move them concurrentlytewards the first and second 'positions-thereof'respectivelywhereby a decrease in the ratio-of treatedmedinm to" non-treated medium is accompanied by an increaseintotal How; and;- vice versa, an increase in said ratio isaccompanied"hy a decrease" in total flow.
  • control means initiates operation of said sliding d'amper prior to initiating operation of" said'proportioning-damper' fromtheir first positions towards their second positions;
  • a device accordingto claim '1" whereinsaid'control means terminates operation of said-slidingdamper after their first-positionstotheirsecond positions.
  • a device including a volume governor disposed in said channel between said inlet and said dampers to maintain the quantity of medium entering said inlet substantiallyiconstant at the flow rate determined by said dampers.
