Definitions

  • ABSTRACT Shutter-type fluid distributor comprises a three-way housing wherein the duct constituting the three ways are spaced angularly from each other and of which two are adapted to be selectively closed by rotation of the shutter in one of two angularly spaced positions thereof.
  • the shutter comprises a pair of substantially parallel flapwalves operatively interconnected, the shutter and housing comprising means such that in one of the duct-closing positions the shutter is adapted to close simultaneously the relevant duct and the third duct of the housing.
  • This shutter is particularly suited for controlling the distribution of fluid in the air-conditioning systems of automotive vehicles and the like.
  • the present invention is concerned in general with means for distributing fluids among various ducts, but has specific reference to a pivoted flapped-shutter distributor, of the type comprising a three-way distributor housing with angularly spaced ducts, wherein two such ducts are adapted to be closed by rotation of the shutter as the shutter is set in one or the other of two angularly spaced positions.
  • a single distributor shutter having a plurality of rigidly interconnected deflector blades or flaps constantly kept at fixed relative angular spacings, or a plurality of single or double flaps controlled separately or by means of coupling linkages interconnecting themare used, all these blades or flaps being adapted to close the inlet or directional distribution of fluids forced into duct means of the corresponding housings.
  • the present invention is directed to a fluid distributor comprising a single shutter having two substantially parallel flap valves, the arrangement being such that the desired portor duct closing positions can be obtained by means of a single control and simple, economical component elements.
  • the shutter-type fluid distributor according to this invention is characterised essentially in that the shutter and housing are provided with means adapted, in one of the duct closing positions, to close at the same time the relevant duct and the third duct of the housing.
  • the two flap-valves of the shutter are operatively interconnected at their ends by means of pivot pins of which one is free and rigid with one of the flaps to constitute a hinge member for the other flap, the other pivot pin being fixed and acting as a common pivot pin to both flapvalves, a bearing member rigid with one of these flap-valves being adapted to be associated with cam means provided within the housing to permit the closing of the third duct by varying the angu- BRIEF DESCRIPTION OF THE DRAWING
  • FIG. 1 shows a three-way shutter-type fluid distributor, in the position closing the ingress to one duct;
  • FIG. 2 is a view similar to FIG. 1 but showing the shutter in the position freeing the ingress to the three ways;
  • FIG. 3 shows the same arrangement with the shutter positioned to close the second way
  • FIG. 4 is a corresponding view showing the distributor with the shutter positioned to close the second and third ways, simultaneously;
  • FIG. 5 shows a modification of the invention.
  • a fluid distributor for example for the air ventilation or conditioning system of a motor vehicle, which comprises a three-way housing 1, has afirst way or duct 2 for directing the fluid upwards, for example for de-misting, defrosting and/or de-icing the windscreen, a second way or duct 3 for directing the fluid downwards, for example for supplying hot or cold air(or any temperature therebetween) into the body of the vehicle, and a third way or duct 4 constituting the fluid supply duct.
  • a shutter of the composite type, designated in genera] by the reference numeral 5, is shown in its upper position in FIG. 1, in which it closes the ingress of duct 2.
  • This shutter comprises a pair of substantially parallel flap-valves or like members 6, 7, i.e. a first, so-called reaction flap 6, which has one end rotatably solid with a free pivot pin 8 constituting a hinge member fitted in a hinge socket 9 rigid with the adjacent end of the other flap 7, said socket 9 being adapted to pivot about the pin 8.
  • Pivoted to another pivot pin 10 constituting the main or general and fixed pivot pin of the shutter 5 is another socket 11 rigid with the opposite end of the second flap 7.
  • a lug 12 is rigidly secured to, or formed integrally with, the second flap 7 and has its outer end connected to the driving end of a linkage member 13, for instance a rod, for controlling the shutter 5.
  • a tension or draw-spring 14 extending within the gap left between the two flap-valves 6 and 7 has its ends attached to anchoring lugs 15 and 16, respectively.
  • the first lug 15 is secured to or formed integrally with, the flap 7 at a short distance from pivot pin 8
  • the second lug 16 is secured to, or formed integrally with, the flap 6 adjacent the fixed pivot pin 10, whereby the spring 14 constantly urges the flap 6 to a position in which it is substantially parallel to the flap 7, the free end of flap 6 then bearing against the socket 11 of pivot pin 10.
  • a bracket 17 receiving the shaft 18 of a bearing roller or follower 19 is rigid with the first flap 6 and extends downwards, as seen in FIG. 1, from a point located at a short distance from the hinge pin 8.'An aperture 20 is formed in flap 7 to permit the free passage of roller 19 therethrough.
  • a sealing strip 21 engageable by the corresponding curved end of flap 6 rigid with hinge pin 8 is provided in the housing 1 at the inlet end of duct 2, as shown.
  • a friction shoe 19' could be substituted for the roller follower l9.
  • the control linkage member 13 and its lug 12 could be disposed outside the housing 1, and the flap 6 of shutter 5 urged towards the other flap 7 by a spiral or torsion spring disposed across the pivot pin 8 carried by flap 6.
  • a flexible cable for example of the Bowden type
  • these means consisting for example of a torsion or spimeans operatively connected with said shutter for causing said two flap-valves, when in one of said first and second positions, to block the respective one of said first and second ducts and to simultaneously block said third duct.
  • Fluid distributor according to claim 1 wherein said two flap-valves of said shutter are operatively interconnected at their ends by means of a pair of pivot pins, a first pivot pin being free and rigid with a first flap-valve to act as a hinge member to a second flapvalve, the second pivot pin being fixed and acting as a common hinge pin to both flap-valves; and said means comprises a bearing member rigid with said first flapvalve being adapted to engage a cam face formed on a cam member rigid with said housing for closing the third duct and varying the angular position of one flapvalve in relation to the other; resilient, means constantly maintaining said flap-valves substantially parallel to each other in allthe other positions.
  • Fluid distributor according to claim 2 wherein one end of the second flap-valve of said shutter is rigid with a socket pivoted to said first pivot pin, the opposite end of said second flap-valve. being rigid with another socket pivoted to said second fixed pivot pin. 4. Fluid distributor according toclaim 2,.wherein said resilient means constantly maintaining said flapvalves substantially parallel to each other comprises a tension spring pre-stressed between the registering faces of said flap-valves inthe vicinity of their pivoted ends. l i
  • Fluid distributor according to claim 2 wherein said resilient means constantly maintaining said flapvalves substantially parallel to each other comprises a torsion spring associated with the free pivot pin in such a way as to urge the first flap-valve rigid with said free pivot pin to a position in which said first flap-valve is substantially parallel to said second flap-valve.
  • Fluid distributor accordingto claim 2 wherein said cam member rigid with said housing comprises a projecting lip disposed at the inlet end of the duct which is to be closed simultaneously with the third duct of the housing, said projecting lip being curved towards flap of said shutter.
