Definitions

  • a preferred output container has two valves, the second valve for Filling the container with both liquid medium and is formed with compressed gas. That from the dispensing valve of the container independent filling valve can meet the needs of Filling can be adjusted without changing another To have to perform a function. Filling with just one valve enables quick filling and uncomplicated Connect with appropriate filling elements.
  • the partition especially the piston, can be a mechanical one Be assigned switching element that when reaching an end position a switching valve after squeezing the liquid volume for the gas supply for the supply of compressed air in opens the dispenser.
  • the switching valve can be outside of the dosing container. With one particularly preferred embodiment is the switching valve in the metering container arranged.
  • the dosing device of the filling device is in one embodiment of the invention preferably as a volume metering device trained which a predetermined volume of liquid dispenses into the dosing container or holds it there. At this embodiment corresponds to the volume of liquid in the Dosing container usually the one to be filled into the dispensing container Volume in the liquid medium.
  • the dosing device can be used to change the desired amount of liquid be adjustable or changeable.
  • In the storage container can be used as a circuit diagram trained float valve can be provided, which over Pressure lines connected to the main switch and at The liquid level drops below a predetermined level Level opens, so that a pressure pulse is given, which the Main switch closes.
  • the shut-off valve for the liquid line and the switching valve for actuating the Main switches can be used together in a float valve be integrated, which performs both functions.
  • This float valve can be removable with the lid so that the Liquid line and the main switch are each closed when the cover is removed.
  • the filling device is like this trained that first filling the dispenser with compressed gas up to a partial pressure, after which liquid is pressed into the dispenser until the predetermined maximum pressure is reached. In this case not volume metering, but pressure-dependent Liquid dosing. Through this embodiment of filling device and filling process ensures that there is always a sufficient gas cushion in the dispenser is that for dispensing those in the dispenser Amount of liquid is sufficient if handled correctly.
  • the pressure-dependent control of the second switching valve can with the help of the pressure difference between Gas pressure in the gas filling line and the liquid or. Gas pressure in the leading from the switching valve to the filler neck Filling line can be made, with relative Overpressure in the gas filling line is preferably the way for the filling with compressed gas is open and with pressure equalization preferably the way for filling with liquid is open.
  • the switch position for the liquid filling with pressure equalization, mechanical pre-tensioning, which acts on the switching element can be achieved.
  • the refill 12 can be done in a simple manner be formed that one of the canister 13 in the metering container 11 leading refill line 22 into the dosing container protrudes and at least the lower end 23 of the Refill line 22 is adjustable in height.
  • the valve 21 is at the lower end 23 of the refill line 22 trained so that it is on the rising liquid level in the dosing tank responds and closes when the liquid level reaches the lower end 23 of the refill line 22.
  • the refill line 22 is still with a mechanical shut-off valve 24 provided for the permanent closure of the Refill line 22 is provided, for example when dismantling the filling device 2 or for cleaning purposes.
  • the dosing container 11 ' can have a larger volume, in particular a volume of liquid, there, as already mentioned, the liquid in this embodiment not metered in volume from the dosing container, but is output in pressure-dosed. Therefore, with the Filling device of this embodiment in principle also different large output containers 1 'are filled.
  • the Pressure line leading from the dosing tank 11 'to the filler neck 9' leads, not continuously trained, but by one Pressure switch 25 interrupted in two sections 26 and 27, the section 26 between the metering container 11 'and Pressure switch 25 is located and the section 27 between the pressure switch 25 and filler neck 9.
  • a gas metering line 28 branched off to the pressure switch 25 leads as the second entrance and in the one as Pressure regulator working pressure regulator 29 is arranged.
  • the control slide 30 is biased by a compression spring 31 in the direction of a slide position, in which the liquid line 26 with the filling line 27 to Control slide 30 is connected.
  • a control line leads 32 from the filling line 27, which in the case of a prevailing fluid pressure acts in the same direction, like the compression spring 31.
  • On the other side of the control spool 30 attacks a control line 33, which in the case of a there prevailing gas pressure a thrust on the spool 30 towards a connection between the gas metering line 28 and the filling line 27 exercises.
  • the pressure regulator 29 reduces that in the gas metering line 28 and Control line 33 prevailing gas pressure to a maximum of 3 bar, whereas the maximum gas pressure in the rest of the gas-carrying system is 6 bar.
  • Control lines 33 and 32 essentially pressure equalization, see above that the compression spring 31 the spool 30 in the other Switched position in which the liquid line 26 in Communication with the filling line 27 comes.
  • the liquid medium is then out dosed into the can 1 and in one such a quantity until the maximum pressure of 6 bar in the can is achieved.
  • the volume-related amount of liquid is included depending on the capacity of the can 1.
  • FIG. 4 shows a Development of the not according to the claimed invention Working embodiment according to FIG. 1. Corresponding to each other Parts are therefore with the same reference numerals Mistake.
  • the dispenser designed as a spray can 1 " has an inclined position when filling, which is easy to handle facilitated. For the rest, the interaction is between Filling valve 8 "and filler neck 9" and the actuation of the Probe 17 "of the reusable valve 15" the same as in the Embodiment according to Fig. 1 or Fig. 2. Also the coding to avoid incorrect operation is appropriate educated.
  • the free end of the piston rod has a mechanical one Stop 48 on the one with an actuator 49 one Switch valve 50 cooperates when the piston 43 hits the bottom 45, i.e. the volume of liquid is squeezed out.
  • the passage for compressed gas is then opened in the switching valve a gas supply line 51 coming from the reusable valve 15 "is released and passes through a further compressed gas line 52 via a check valve 53 in the filling line 54, the leads to the filler neck 9 ".
  • a check valve 57 enables easy suction of liquid from the Storage container and prevents backflow of liquid when squeezing the volume of liquid into the dispenser 1 ". Conversely, a check valve prevents 58 in the from the dosing 11 "to the filler neck 9 "leading filling line 54 a suction of gas or Liquid from the filling line as long as in the dosing tank 11 "there is a relative negative pressure.
  • the from the reservoir 13 '' 'to the liquid space of the Dosing container 11 '' 'leading liquid suction line 71 again extends from the bottom of the storage container 13 '' ' a lid 72 of the storage container and leads over Check valve 73 in the area of the container bottom 64 in the Liquid space of the metering chamber 11 '' '.
  • the check valve 73 becomes like the check valve 57 of the embodiment Fig. 4 when returning the piston to its initial position due to the relatively reduced pressure due to suction opened so that liquid from the reservoir can flow. Will the piston 62 on its back with Pressurized gas is applied, then the check valve prevents a backflow of liquid to be added.
