  • Fig. 1 shows the fluid chamber 22 with the container interior 13 in Fluid connection, namely through an annular gap between the End portion 31 of the plunger 26 and the annular projection 32 of the Container opening 23 through.
  • Fig. 1 shows the metering valve in Closed position.
  • Fig. 2 the fluid chamber 22 from the container interior 13 through separated the larger diameter portion 27 of the plunger 26.
  • the container opening 23 is through the below the inside the transverse bore 30 located part of the first Tappet section 27 blocked.
  • Fig. 2 there is Dispensing valve in the dosing position, d. H. in position to dosed discharge of the fluid in the fluid chamber. Accordingly, the dosage is determined by the volume of the Fluid chamber 22 in the valve body 16 determined.
  • Fig. 3 the dispensing valve is in one position for a continuous fluid discharge from the Inside the container 13.
  • the valve body opening 23 or its Ring projection 32 is through the two transverse bores 29, 30th and bridged axial bore 28, so that a permanent Fluid connection between the fluid chamber 22 and the Container interior 13 is made, via the Riser 24.
