Definitions

  • APPARATUS FOR ADJUSTING A FLUID ABSTRACT The valve provides an unrestricted flow through THROUGHPUT a chamber from a first opening to a second opening while the reverse flow is first adjusted to a fine extent so as to allow a 3 Chums 2 Drawmg Figs gradual increase in flow until full throughput is reached. To this end a large primary closing member engages the first opening so as to be urged off its seat under the action of the fluid entering said opening whereas the opposite flow seats said primary closing member.
  • the present invention has for its object an apparatus adapted to ensure a fine adjustment of a fluid output, more particularly an adjustment of the throughput for one direction of flow while the flow in the opposite direction remains unrestricted.
  • the present invention has for its object elimination of said difficulty and it is directed to an apparatus for adjusting a fluid throughput, of the type including a chamber provided with two openings for the passage of the fluid, a first closing member adapted to slide axially within said chamber between a closing and an opening position while a second closing member is adapted to be shifted axially by a control member with reference to a port provided for the fine adjustment of the fluid throughput.
  • the two closing members are coaxial and have different cross sections, the port provided for the fine adjustment of the fluid throughput being formed through the wall of the first closing member.
  • FIG. 1 is a longitudinal sectional view of said embodiment
  • FIG. 2 is a graph illustrating the flow of fluid through the apparatus.
  • Said apparatus comprises as illustrated a body 1 enclosing a cylindrical chamber 2 provided with two ports 3 and 4.
  • a bellshaped, first closing member 5 made of plastic material is slidingly carried inside said chamber so as to be capable of moving axially therein towards and away from the opening 3.
  • the upper section 6 of the closing member 5 is adapted to engage fluidtightly a seat formed by the shoulder 7 at the entrance of the opening 3 when the closing member is in its operative closing position illustrated in FIG. 1.
  • the skirt of the closing member 5 is providedwith longitudinal slots such as 8 which afford a permanent communication between the inside of the closing member 5 and the lateral opening 4 of the chamber 2 whatever may be the axial position of said closing member inside the latter.
  • the closing member 5 shows a port 9 through which a fine adjustment of the throughput may be obtained and the part played by which will be disclosed hereinafter with further detail.
  • Said port 9 affords a communication between the opening 3 of the chamber 2 and the inside of the closing member 5 and therefore between said opening 3 and the lateral opening 4 of said chamber.
  • the body 1 is tapped as shown at 10 so as to be engaged by the threads 11 on one end of a cylindrical section 13 which is disposed with a slight friction fit inside the chamber 2.
  • Said cylindrical section 13 is provided on its outer surface with an annular groove 14 inside which is fitted a fluidtight toreshaped packing 15.
  • a rod 16 coaxially rigid with the cylindrical section 13 may engage, with a slight amount of friction, the port 9 in the closing member 5 to thus provide a second closing member.
  • the cylindrical section 13 further includes a tubular extension 17 at its end facing the closing member, said extension being coaxial with the rod 16.
  • the outer end of said tubular extension is provided with an outer shoulder 18 adapted to engage an inner flange 19 at the corresponding end of the closing member 5.
  • the latter is rigid with an inner central tubular extension 12 adapted to guide a coil spring 20 fitted in a compressed condition between the upper inner surface ofthe closing member 5 and the bottom of the tubular extension 17 of the screw 11.
  • the fluid may escape from the inside of the closing member 5 towards the opening 3 through said port 9.
  • the latter Upon screwing of the screw 11, the latter is caused to progress within the chamber 2 so as to gradually reduce the cross section afforded for the passage of the fluid through the port 9, the flow of fluid being arrested when the rod 16 closes completely the port 9.
  • the graph of FIG. 2 illustrates the variations of the fluid throughput through the free cross section in the direction from B towards A that is from the opening 4 towards the opening 3, said graph carrying in ordinates the throughput Q and in abscissae the shifting C of the screw 11, the graph being drawn. for an unvarying drop in pressure in the adjusting apparatus.
  • the rod 16 gradually uncovers the port 9. Since the cross section of said port 9 is very small with reference to the cross section of the opening 3, it is obvious that the axial shifting of the rod 16 with reference to the port 9 allows a very fine adjustment of the throughput of fluid flowing from the opening 4 towards the opening 3, this being illustrated in FIG. 2 by the section a of the curve for which section a shifting a of the screw 11 carrying along with it the rod 16 is proportional to the throughput Q.
  • An apparatus for adjusting a fluid throughput comprising a body enclosing a chamber provided with a first opening and with a second opening, a first closing member adapted to slide inside the chamber between an operative position closing the first opening and an inoperative position uncovering said first opening, said first closing member being provided with a port facing said first opening, a second closing member the diameter of which is smaller than that of the first closing member, said second closing member comprising a cylindrical rod slidable coaxially within the first closing member in axial registry with the port in said first closing member between an operative position in which it slidably and frictionally engages said port and an inoperative position out of engagement with said port permitting an adjustably reduced flow of fluid out of the second opening through said port towards the first opening, the locationof said rod relative to said port defining the flow of fluid through said port, means controlling the position of the first and second closing members, said means controlling the position of the first and second closing members controlling the position of said second member independent of fluid conditions in said apparatus, said first closing member being substantially bell-shaped
  • the means controlling the position of said first and second closing members includes a member threadedly engaging the body and coaxially rigid with said second closing member, the rotation of said threadedly engaging member defining the axial shifting of the second closing member with reference to the port in the first closing member.
  • said threadedly engaged member includes abutting means engaging the first closing member for shifting it into an open position when the second closing member'has been moved over a predetermined value thereby controlling the position of said first closing member.
