Definitions

  • the invention relates to a fluid mixing system mainly comprising a fluid pump, a fluid gauge based on the displacer principle and a dosing pump coupled with the main duct system.
  • the invention relates to a petrol pump having a volume meter, in which precautions are taken to add a fluid such as mixed lubricant, anti-knock agents and the like in very accurately dosed amounts.
  • a fluid such as mixed lubricant, anti-knock agents and the like in very accurately dosed amounts.
  • Other applications are, however, not excluded.
  • the most conventional petrol pumps comprise a volume gauge based on the displacer principle and they have two or more single- or double-acting pistons, the reciprocatory movement of which is converted into a rotary movement of a crank shaft.
  • the rotation drives a counter either directly or through a pulse producer and an electronic processing system. This system measures accurately at highly varying rates.
  • pistons, piston rods and crank shafts of the volume gauge will be termed "moving parts”.
  • the dosing pump may be a plunger pump in which the reciprocatory movement of the plunger (piston) is derived from the rotary movement of the crank shaft of the volume gauge.
  • the rotary movement of the crank shaft may, as an alternative, be transferred to the shaft of a rotary displacer pump, for example, of the gear wheel type.
  • the volume gauge and the pump perform the same strokes.
  • the stroke (volume) of the dosing pump may be controlled by means of an adjustable stop. It is then required that the connection between the plunger of the pump and the piston of the gauge should be compressible.
  • the outlet of the dosing pump is connected with the main pipe system of the gauge.
  • the gauge is connected with this system.
  • the main fluid stream and the injected stream are then commonly measured on a quantitative basis, which, if of course, usually desired. Moreover, there is a reasonable chance of a satisfactory mixing in the gauge.
  • the invention will be explained with reference to a drawing which illustrates the preferred embodiment in which the piston of the gauge and the plunger (piston) of the displacer pump are coupled.
  • the Figure is a sectional view of a volume meter known per se operating on the displacer principle and basically comprising two pistons 2 and 2' coupled with piston rods 1 and 1 1 and 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 fluid (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 of the volume gauge.
  • a tie rod 8 Through a tie rod 8 the movement of the piston 2 is transferred to a plunger (piston) 9 adapted to move in a cylinder 10.
  • the tie 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'.
  • the Figure shows the preferred embodiment in which the outlet duct 13 is connected with the main feeding duct 5.
  • the main stream and the additive are thus commonly measured quantitatively.
  • the stroke of the plunger of the dosing pump can be set.
  • the tie 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:
  • each of the pistons 2, 2' etc. with a separate dosing pump 8, 9, 10, etc. so that more than one fluid can be injected into the main stream, each in the desired, set dose with respect to the main stream 5.
  • the mixing system particularly relates to a petrol pump with additive dosing capacities. 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.
