Definitions

  • the present invention relates to devices for dividing into at least two portions a stream of a mixture of a liquid fluid and a gaseous fluid, such a device comprising a single inlet pipe and at least two outlet pipes between which the mixture supplied by the inlet pipe is to be divided into portions of identical respective volume and composition.
  • the invention is more especially concerned with devices of this kind for mixtures of a liquid fuel and of a gaseous combustion supporting gas, generally air, such a mixture being fed from a single carbureiting device and being intended to be distributed among the cylinders (or group of cylinders) of an internal combustion engine.
  • a carburetor with a flow dividing device has been described in my US. Patent No. 3,198,498 of Aug. 3, 1965, for Pressure Carburetors.
  • the object of the present invention is to provide a device of the type described which is better adapted to meet the requirements of practice than those existing at the present time and in particular which is capable of sending into each of the outlet pipes a mixture of the same composition and volume at any time.
  • the invention consists chiefly in arranging the device so that it comprises, in addition to a main circuit through which the mixture fed from the inlet pipe is caused to flow in front of the inlets of the outlet pipes in a direction substantially at right angles to said inlets, an auxiliary circuit capable of returning to the inlet pipe the remainder of the mixture which has flown past said inlets without penetrating thereinto, the system being preferably such that the circulation of the mixture arriving through the inlet pipe creates a suction in the portion of the auxiliary circuit opening into said inlet pipe, which suction has for its effect to accelerate the mixture flow through the auxiliary circuit.
  • FIGS. 1 and 2 show, in axial section on the line 1-1 of FIG. 2 and in plan view, respectively, a first embodiment of the device according to the present invention
  • FIG. 3 and 4 are respectively an axial sectional view on the line IIIIII of FIG. 4 and a plan view of a second embodiment of the invention
  • FIG. 5 is an axial sectional view of a device made according to a third embodiment of the invention.
  • FIG. 6 is a sectional view on an enlarged scale of a portion of the device of FIG. 5;
  • FIG. 7 is an axial sectional view of a device made according to a fourth embodiment of the invention.
  • FIGS. 8 and 9 are an axial sectional view on the line VII IVIII of FIG. 9 and a plan view, respectively, of a device made according to a fifth embodiment of the invention.
  • the device according to this invention comprises a mixture inlet pipe 1 receiving, for instance, an air and fuel mixture under pressure, and at least two outlet pipes 2 (for instance four such pipes, as illustrated by the drawings) connected to respective intake pipes of an internal combustion engine.
  • the device comprises, on the one hand, a main circuit for the circulation of the mixture from inlet pipe 1 to the inlets 2a of outlet pipes 2, the mixture flowing through said main circuit in a direction substantially perpendicular to that of the pipes 2 and, on the other hand, an auxiliary circuit for returning to inlet pipe 1 the portion of the mixture that has flown past inlets 2a without entering them.
  • the outlet pipes 2, at least the portions thereof adjoining their inlets 2a, are disposed, at least approximately, in a common cylindrical surface the axis of which coincides with the end portion of inlet pipe 1.
  • the main circuit is located in a plane perpendicular to said axis and passing substantially through the end of pipe 1.
  • the main circuit consists of conduits 3 extending radially from inlet pipe 1 and each of which leads to the inlet end 2a of an outer pipe 2.
  • the auxiliary circuit is constituted by conduits 4 which form extensions of conduits 3 beyond the ends 2a of conduits 2 and by conduits 5 and 6 which connect conduits 4 with inlet pipe 1 at a point thereof upstream of conduits 3.
  • Every main circuit branch 3 and the corresponding auxiliary circuit branch 4-5-6 are disposed in a plane passing through the axis of the end portion of inlet pipe 1.
  • conduits 5 are disposed along the generatrices of a cylinder or cone of revolution about this axis.
  • the device is arranged so that the flow of mixture through inlet pipe 1 creates a suction in the portion of the auxiliary circuit branches adjacent to said inlet pipe 1.
  • conduits 6 are oblique with respect to inlet pipe 1 so that their outlets 6a, through which they open into said pipe 1, are located at the front of said conduits in the direction of circulation through inlet pipe 1.
  • FIGS. 1 and 2 works as follows:
  • Inlet pipe 1 supplies an air and liquid fuel mixture which, at the outlet of said pipe 1, is divided among the respective conduit 3. It is found that, if the auxiliary circuit 4-5-6 is stopped, the air and fuel mixture at the end of pipe 1 is not homogeneous, so that some of the outlet pipes 2 are fed with more liquid than the others. On the contrary, with the auxiliary circuit 4-5-6 in operation, the mixture flowing through conduits 3 passes across the inlets 2a of outlet pipes 2 with a very high velocity and the portion of said mixture which has not passed into outlet pipes 2 is reintroduced into pipe 1 through holes 6a, this mixture being homogenized downstream of said holes 6a and, in particular, at the inner ends of conduits 3. Thus, owing to the provision of auxiliary circuit 4-5-6, the amounts of liquid fluid and gaseous fluid, respectively, conveyed through pipes 2 are made equal for all of said pipes.
  • the main circuit is constituted by a common chamber 7 the walls of which are substantially perpendicular to the axis of the end portion of inlet pipe 1, said walls being sufficiently close for causing the mixture to flow with a high velocity across inlets 2a of pipes 2.
  • the distance between these walls may be of the order of 0.3 mm.
  • the auxiliary circuit comprises an annular extension 8 of chamber 7 beyond the inlets 2a of outlet pipes 2.
  • the auxiliary circuit further comprises an annular groove 9, the axis of which coincides with that of the end portion of inlet pipe 1, and several conduits 10 opening at 10a into inlet pipe 1.
  • annular groove 9 the axis of which coincides with that of the end portion of inlet pipe 1, and several conduits 10 opening at 10a into inlet pipe 1.
  • said orifices are located in the neck of a venturi 11 provided in pipe 1.
  • FIG. diflers from that of FIGS. 3 and 4 by the fact that it comprises a single transverse chamber 12 to replace the conduits of FIGS. 34. Furthermore, oblique conduits 13 are interposed between chamber 12 and a groove 9a analogous to the groove 9 of FIG. 3. Finally, the venturi 11 of FIG. 3 is replaced by a suction device arrangement shown on an enlarged scale by FIG. 6.
  • This device comprises a portion 14 of pipe 1, located between chambers 12 and 7, the inlet of which (in the direction of circulation illustrated by the arrows) has a cross section a little greater than the remainder of pipe 1, said portion 14 diverging toward the top. Owing to the provision of this pipe portion 14, the sream of mixture fed through pipe 1 produces a suction over the whole periphery of chamber 12 and consequently in conduits 13, which activates the circulation in auxiliary circuit 8, 9a, 13, 12.
  • FIG. 7 differs from that of FIG. 5 by the provision of a plurality of passages 15 which replace the whole of groove 9a and conduits 13. Each of these passages 15 is advantageously located in an axial plane passing through the end 2a of a pipe 2.
  • FIGS. 8 and 9 differs from that of FIG. 7 in that every outlet pipe 2, instead of having a single inlet 2a, includes two such inlets 2b and 2c disposed transversely with respect to chamber 7 and connected together as shown by FIGS. 8 and 9.
  • inlets 2b and 2c are located at two points of chamber 7, '8 remote from each other.
  • said inlets may be disposed on a circle the center of which is located on the axis of the end portion of inlet pipe 1.
  • Three inlets might be provided for every pipe 2 and in this case their total number would be twelve.
  • the latter may be oblique with respect to the above mentioned axis, as shown by FIG. 8.
  • the device when the main auxiliary circuits are constituted by separate conduits (FIGS. 1 and 2), the device may be constituted by a single piece provided with suitable bores, the latter being stopped at their outer ends by plugs 16.
  • one of the circuits comprises at least one continuous chamber such as 7, 8 or 12 (FIGS. 3 to 9) the device is generally constituted by pieces joined together along planes passing through said chambers to permit machining thereof.
  • the operation of the embodiment of FIGS. 3-4, 5-6, 7, 8-9 is the same as that above described with reference to FIGS. 1-2.
  • a device for dividing into at least two portions a steam of a mixture of a liquid fluid and a gaseous fluid which comprises in combination
  • a mixture inlet pipe at least two mixture outlet pipes, means forming a mixture main path connecting the outlet end of said inlet pipe with the inlets of said outlet pipes, said main path extending substantially at right angles to said mixture outlet pipe inlets,
  • a device wherein the portions of said outlet pipes adjoining the inlet ends thereof are disposed along generatrices of a cylinder the axis of which is that of the end portion of the mixture inlet pipe, the mixture main path being disposed in a plane prependicular to said axis and switch passes substantially through the end of said mixture inlet pipe.
  • a device according to claim 1 wherein the mixture main path consists of two conduits each extending from the outlet end of the mixture inlet pipe to the inlet of one of said mixture outlet pipes.
  • a device according to claim 1 wherein the means forming the mixture main path consists of a chamber limited by two fiat walls close to each other and perpendicular to the outlet end of said mixture inlet pipe.
