Definitions

  • the "present invention relates to carburetors and, more especially, to those of the socalled submerged nozzle type. V
  • Submerged nozzle assemblies are general 1y composed of (Fig. 1) a calibrated orifice or nozzle positioned at the bottom of a discharge tube which communicates through a series of orifices at different levels with a surrounding well.
  • the fuel in said well serves primarily to supply additional fuel during acceleration of the motor.
  • air is drawn through said orifices at different levels to form an emulsive mixture with fuel supplied by the calivbrated submerged nozzle of the discharge tube.
  • One of the objects of the invention is to providemeans for preventing a too rapid evacuation of wells of the type described in assemblies of this nature.
  • FIG. 1 is a diagrammatic section through one illustrative embodiment of the invention
  • Fig. 2 represents, in a similar manner another possible form
  • Fig. 3 is a detail of the nozzle assembly shown in Fig. 1;
  • Fig. 4 represents, in section, the form of nozzle illustrated in Fig. 2;
  • FIG. 5 and 6 show, in section, two other possible forms that the invention may take.
  • a mixing chamber 1 controlled by a valve 2, a venturi 3, an auxiliary mixing chamber 4 supplied with alcohol from an auxiliary or low-speed nozzle 5, a float chamber 6 of current design supplying fuel via a passage 7 to auxiliary nozzle 5 and submerged nozzle 8, a passage 9 delivering emul- 4 sion to outlet 10 and provided with solvent via a plurality of orifices of the type 12, 13, 14, a well 11 an external envelope 15 having an air inlet 16 formed therethrough, and a ring 1-9 leaving a small annular space 18 bel tween orifices 12 and 13.
  • Ring 19 may pre sent a series of superposed capillary passages as shown or have an internal cylindrical wall.
  • the hereinabovedescribed device differs from those now in current use only in the adjunction of ring 19.
  • the latter by restricting the section of the lower part of the well 11, interposes a capillary resistance to the emptying of the latter. If, then, during acceleration, the liquid in well 11' is drawn rapidly through orifices 13 and A, its movement through orifice 12 is impeded by the capillary resistance offered by annular passage 18 and the suction exerted on nozzle 8 will rise to the maximum necessary to insure the maximum feed desired during the acceleration period.
  • auxiliary nozzle 5 receives fuel from well 11 and the restricting effect of ring 19 of Fig. 3 is obtained by forming an annular extension 17 on tube9so as to limit a capillary passage 18 havingthe same function as the one already described"
  • tube 9 not only carries an annular extension 17 but is of different internal section at thetop and bottom.
  • Fig. 6 differs from thoseshown in Figs. 1 and 5, in
  • any one of the devices shown in Figs. 3 to (5 may function with auxiliary nozzles of the type shown in either Figs. 1 or 2, passage 9, shown as having a uniform internal diameter in Figs. 3 and 4:, may be of diminished internal diameter at its lower end, as shown in Figs. 5 and 6; any one of passages 18, represented in Figs.” 3 to 5 may be given the superposed form illustrated in Fig. 6 and vice-versa; etc.
  • a liquid fuel reservoir a liquid fuel reservoir
  • a nozzle assembly comprising a calibrated nozzle communicating with said reservoir, said nozzle being below the normal level of liquid fuel in said reservoir, a first tube having a plurality of orifices in the walls thereof at different levels and positioned above said calibrated nozzle, and a second tube positioned outside said first tube, said second tube communicating with the atmosphere, said first and second tubes being formed so as to define reduced capillary annular sections of the space in the well positioned between successive levels of the orifices in the walls of the first tube, and a mixing chamber positioned to exert suction on said nozzle assembly.
  • a liquid fuel reservoir a liquid fuel reservoir
  • a nozzle assembly comprising a calibrated nozzle communicating with said reservoir, said nozzle being below the normal level of liquid fuel in said reservoir, a first tube having a plurality of orifices in the walls thereof at different levels and positioned above said calibrated nozzle, and a second tube positioned outside said first tube, said second tube COlDlIlUHlCZltiD with the atmosphere, said first and second tubes being formed so as to define reduced capillary annular sections of the space in the Well between the levels of the two orifices in the walls of the first tube which are nearer the bottom of said well.
  • a liquid fuel reservoir a liquid fuel reservoir
  • a nozzle assembly comprising a calibrated nozzle communicating with said reservoir, said nozzle being below the normal level of liquid fuel in said reservoir, a first tube having a plurality of orifices in the walls thereof at different levels and positioned above said calibrated nozzle, and a second tube positioned outside said first tube, said second tube communicating with the atmosphere, said first and second tubes being formed so as to limit capillary annular sections of the space in the well positioned between the levels of the orifices in the walls of the first tube, said capillary annular section being in series with one another.
  • said first and second tubes being formed so as to define reduced capillary annular sections of the space in the well positioned between successive levels of the orifices in the walls of the first, said annular capillary sections being positioned in series with one another between successive orifices in the wall of the first tube.
