Definitions

  • the invention relates to a fluid mixing system comprising a fluid pump, a fluid amount meter based on the displacer principle and a dosing pump coupled with the main pipe system.
  • the invention aims at providing a petrol pump having a fluid amount meter, in which there are provisions for adding a fluid such as mixed lubricant, anti-knock agents and the like in very accurately dosed amounts. Other applications are, however, not excluded.
  • the problem of accurate dosing is solved when: the dosing pump is of the displacer type and is mechanically coupled with one of the moving parts of the fluid amount meter.
  • the dosing pump may be a plunger pump of which the reciprocatory movement of the plunger (piston) is derived from the rotary movement of a crank shaft of the fluid amount meter by means of a connecting -rod.
  • the rotary movement of the crank shaft may, as an alternative, be transferred to the shaft of a dosing pump of the rotary type such as a gear wheel pump.
  • a very simple and satisfactorily controllable dosing system is obtained when the connecting rod extends between the plunger of the dosing pump and a piston of the fluid amount meter.
  • the plungers of the fluid amount meter and the dosing pump perform the same stroke.
  • the stroke of the dosing pump plunger may be adjustable by means of a stop in conjunction with a compressible part of the connecting rod.
  • the outlet of the dosing pump is connected with the main pipe system of the fluid amount meter.
  • the dosing pump outlet is connected with this system.
  • the main fluid flow and the injected flow are then commonly measured on a quantitative basis, which is of course usually desired. Moreover, there is a reasonable chance of a satisfactory mixing in the fluid amount meter.
  • the invention will be explained with reference to a drawing which illustrates the preferred embodiment in which the piston of the fluid amount meter and the plunger (piston) of the dosing pump are coupled.
  • the Figure is a sectional view of a fluid amount meter known per se operating on the displacer principle and basically comprising two pistons 2 and 2' coupled with piston rods 1 and 1' adapted to move in cylinders 3 and 3' (forming a unit).
  • the piston system 1, 1', 2, 2' is capable of rotating a shaft 4 upon the supply of a fluid such as petrol through a duct 5 by means of a pump (not shown).
  • a rotating valve 6 is rigidly secured to the shaft 4. This valve 6 allows fluid to enter alternatively the cylinders 3 and 3', whilst upon introduction into one cylinder the fluid is expelled from the other towards the outlet 7 (in the direction indicated by the arrow).
  • the shaft has coupled with it a pulse producer.
  • the generated pulses are processed by an electronic system (not shown), which finally displays the number of litres dispensed as well as the amount due.
  • the shaft 4 may, as an alternative, be coupled with a gear wheel pump (not shown), which injects fluid into the main stream simultaneously with the rotary speed of the crank shaft 4 of the fluid amount meter.
  • the connecting rod 8 Through a connecting rod 8 the movement of the piston 2 is transferred to a plunger 9 adapted to move in a cylinder 10.
  • the connecting rod is, of course, sealed with respect to the cylinder space 3.
  • the dosing pump comprising the plunger 9 and the cylinder 10 is, in this case, double-acting, for which purpose the inlet duct 11 includes valves 12 and 12' and the outlet duct 13 includes the valves 14 and 14'.
  • outlet duct 13 is connected with the main pipe system 5.
  • the main flow and the additive are thus commonly measured quantitatively.
  • the stroke of the plunger 9 of the dosing pump can be set.
  • the connecting rod 8 has to be compressible in this case, which is schematically shown by a spring 16.
  • Adjustment of the pump is furthermore possible by means of fixed or adjustable stops in the meter cylinder covers, and/or stop 15 in the dosing pump cover, as the case may be.
  • each of the pistons 2, 2' with a separate dosing pump 8, 9, 10 so that more than one fluid can be injected into the main flow, each in the desired, set dose with respect to the main flow through pipe 5.
  • the mixing system particularly relates to a petrol pump with additive dosing capabilities. This will be particularly important when lead-free petrol is prescribed and anti-knock additives have to be added to the petrol. Moreover, special two-stroke oil need no longer be kept on stock when a pump embodying the invention is employed.
