Definitions

  • the invention relates to a dispenser with which media are stored, which can be promoted or carried out liquid, pasty, gaseous, powdery and / or solid are.
  • the dispenser is dispensing with a single user hand to carry and operate. It exists partially or made entirely of injection molded or plastic parts, of which any rigid, elastic or tension-free flexible can.
  • the donor can only dispense a single media dose or separate for the successive discharge Media boxes should be trained.
  • the discharge stroke to be carried out for this can only be provided in one direction or connect to a return stroke through which one Dosing or pumping chamber after discharge with the Medium is filled.
  • the operation to control the dispenser determines an activation measure that the path of the called opening or closing or the stroke and also that Media volume, which can be in a single Discharge process promoted in the donor or from this is expelled. This measure of activation is advantageous changeable, especially around the different Funding characteristics of the medium to meet or the Change media dose.
  • a closure is provided by the dispenser, which is only closed open or close and conveniently a reversible is opening and closing valve.
  • the actuating means can The return stroke position of the pump piston can be changed by a stop determine if the adjusting means one in opposite Stops adjustable in directions parallel to the piston stroke include against which the piston strikes during the return stroke.
  • the forward stroke of the piston is also by a stop limited.
  • the valve can be a destructible closure or Inlet or outlet valve for a chamber like that Pumping chamber.
  • the invention is also based on the object of a donor to create the disadvantages of known training are avoided and so its actuation or adjusting means act the valve that its control are affected can. Furthermore, the dispenser should be simple in structure or in the Handling as well as safe in the functions.
  • the actuating means can act so that the Relative position of the valve body in one or both end positions of the valve regardless of the setting by the Adjustment means remains the same, reducing the functions of the valve remain constant.
