  • the conditioner housing outlet 59 opens into a. chamber Bi! having an outlet opening B-C defined by the oppositely curving edge portions 3 yand 4 of the cham-
  • This outlet opening B--C is controlled by a disc valve 5 having an insulating gasket 5a.
  • the valve 5 is mounted on an arm 58 vvh-ich in turn is carried by an angular member 5B that is pivotally suspended from a support II by means of a pivot I2.
  • the support II is fastened by screws Ilia and b to an insulator I4.
  • the flexible plate valve I7 extends obliquely upward from the top of the housing I9 and its free end is disposed for positioning cooperatively with respect to and between the ceiling duct wall member I5 and the angular plate 35.
  • the flow area through the by-pass passage I3 is made to increase gradually lengthwise of the duct or channel thereby minimizing noise that otherwise might result from 4the new and intermixing of the two streams of the medium in the duct.
  • the edge of the flexible plate valve at the inlet to the duct is provided with a bulbous conguration 33 to minimize resistance to the flow or" the medium inwardly of duct or channel.
  • a lug 2 is mounted on the underside of the plate valve ll adjacent its free end and connected to this lug is a actuator rod the upper end 263 of which is projected through an opening in the lug 20.
  • the lower end of the rod is connected to a segment arm which is pivotally mounted on a shaft 43 that is iixedly mounted in an upright plate 4l.
  • the outer portion of the arm i5 is provided with a plurality oi openings in which the lower end of the rod 25 may be selectively engaged to efiect the required movement of the flexible plate valve I l.
  • the segment arm 55 and the arm 58 are interconnected by means of a tierod 5I.
  • valves 5 and Il together with their common actuating means as shown in the drawings is such that in the fully open position of the nexible plate valve I'i, i. e., maximum opening at E-F, the quantity of the medium caused to pass through the conditioning means 5 is approximately one-half as great as the amount of the medium which is caused to flow through the bypass I3 when the opening E--F is entirely closed by the plate valve I'i.
  • An advantage of this construction is that no separate regulating valve is required for the inlet to the conditioning means 54.
  • valve disc 5 may be moved into closing engagement with outlet 3a after the valve Il is closed with respect to the by-pass i3.
  • an arm 45a is pivoted on a shaft 3a.
  • the upper end of this arm 45a is connected to a lug a at the underside of the plate valve Il by means of a rod 25a which has its lower end portion selectively 4 engaged in one of a series of openings 41a, 48a, 49a and 50a in the arms 45a and has its upper end similarly engaged in one of a series of openings in the lug 2M.
  • This construction permits continued movement of the mechanical interconnection between the valves 5 and I'I so that the valve 5 may be moved into closing engagement with outlet opening 3a after the plate valve I'I has been moved to closed position with respect to the by-pass I3, thereby to entirely shut-oit now through the duct or channel.
  • a device for regulating the proportions of the conditioned and non-conditioned portions of a gaseous medium comprising, a duct through which the medium is adapted to flow having an inlet opening at one end and an outlet at the otherend, partition means in said duct defining therein a by-pass passage and a conditioning passage having an inlet and an outlet opening, conditioning means in said conditioning passage, a disc valve coopera-ble with said outlet opening of the conditioning passage, a flexible plate valve mounted in the by-pass passage and extending obliquely therein crosswise of the icy-pass passage with its free end portion confronting the duct inlet opening and selectively positionable between opposite sides of the duct inlet opening to cause the incoming medium to i'low through the conditioning and by-pass passages in proportions ranging from zero t0 maximum in the respective passages, and means mechanically interconnecting said flexible plate and disc valves for conjoint operaticn thereof constructed to cause the disc valve to move in opening relation to the conditioning passage outlet as the iiexible plate valve moves in closing
  • conditioning means is a heat exchanger and the conditioning passage occupies the lower portion of the duct with the iiexilole plate valve extending longitudinally of theupper portion of the duct between the partition means and the top wall of the duct.
  • a device as claimed in claim l wherein means is provided in the duct defining a chamber at the outlet from the conditioning means in which the disc valve is disposed and having Va funnel shaped discharge opening into the duct for the conditioned portion of the medium.
