Definitions

  • porous wall may assume the shape of two coaxial cylindrical elements between which a space is provided for containing the fuel.
  • Carburation for idling of the engine may be obtained through a licking or sweeping action of the air over the outer wall of the outer cylinder, while carb-uration for power operation is obtained through a licking or a sweeping of the air over the internal surface of the inner cylinder.
  • carb-uration for power operation is obtained through a licking or a sweeping of the air over the internal surface of the inner cylinder.
  • the reverse arrangement may be provided.
  • the carburetter includes a cylindrical casing l provided at its lower end with a certain number of perforations 2; the space inside said cylindrical casing I is closed at its lower end by a transverse partition 3; said partition 3 is provided with a central opening 4 forming a conical seat.
  • the lower compartment 5 bounded by or formed inside the bottom member 6 communi- ⁇ cates with the outer atmosphere through ports 'I ⁇ adapted to produce a circulation of air through the casing which is much more considerable than that afforded by the perforations 2.
  • the partition 3 carries in a fluid tight manner va body 8 of porous material, for example of the china material used generally for ltration purposes, and including an inner annular element 9 and an outer annular element I0, said elements being connected at their upper end through the transversal member I I.
  • the porous body 8 is advantageously made of one part. It provides between the elements B and I II an annular interval 1 ⁇ Claim. (Cl. 261-99) 2 or chamber I2 communicating with a reservoir-or a supply of liquid fuel.
  • a plunger tube IZa which may be of capillary size and which stretches up to a point very near the connecting member II and opens into the atmosphere above the liquid inside the chamber I2.
  • a movable closing member I4 which is substantially sleeve-shaped and which terminates at its lower end in a conical part I5 cooperating with the seat 4.
  • the movable closing member i4 moves over and along a guiding member I 4a rigid with a spindle It secured to the transverse partitions Il and 6.
  • a spring ZI is inserted between the guiding member Ida and the conical part I5.
  • the weight of the movable closing part I4 is chosen in relationship with ⁇ the size of the chimney I3.
  • the porous body 8 carries an upper transverse partition I'I separated towards its periphery from the casing I by an annular gap I8; the central part of said partition II is provided with perforations IS.
  • the concave portion 2! forming the upper part of the casing I opens into an admission pipe 22 the entrance into which is coptrolled by an admission throttle valve 23.
  • a pipe 24 provides for the admission of gasoline into the annular charnber I2.
  • the conical part I4 rests on the conical seat 4 as illustrated in Fig. l.
  • the air sucked in by the motor enters then into the carburetter through the perforations 2 and ilows through the interval comprised between the outer annular element I9 and the casing I.
  • the air licks the outer wall of said element whereby it becomes loaded with gasoline or the like liquid fuel; it then reaches the admission pipe 22 through the annular gap I3.
  • the pipe I2a serves to blow oif the air pushed ahead by the in-flowing gasoline.
  • the weight of the movable member I4, its diameter, its length, the strength of the antagonistic spring 2B, the weight of the whole system, the diameter of the inner element 9 form means allowing a very simple and very accurate adjustment.
  • a carburetter for liquid fuel in internal combustion engines comprising an outer perforated cylindrical casing, an element of porous material mounted inside the casing with a narrow annular gap between it and said casing, said element being constituted by two substantially coaxial cylinders dening Ibetween one another an annular chamber for a liquid fue1, means for admitting said liquid into the lower end of said chamber, means for venting the air from the upper end Vof said chamber, a support for the porous element secured to the casing provided with an inner chamber communicating with the vatmosphere and with the chamber dened by the inner cylinder, a valve adapted to close the communication between the chamber in the support and last mentioned chamber, a spring urging said valve into its operative closing position, against the suction of the engine and means whereby the engine is adapted to suck air through the perforations of the casing and through the support and to cause the same to sweep over the wall of the outer cylinder and over the inner wall ofthe inner cylinder and to be laden thereby with vaporized fuel.
