  • the germ filter lies within the active substance store mentioned, as a result of which it is effectively protected against mechanical loads or damage and only comes into contact with the air which flows into the store through the ventilation connection for volume compensation.
  • a particularly simple assembly is obtained if the germ filter is arranged on an active substance discharge pump, such as the housing of a manually operated piston pump.
  • the germ filter is expediently arranged at approximately constant intervals on a wall surface which is approximately curved about the central axis of the discharge channel and / or immediately afterwards on a fastening flange of the discharge pump which projects above this wall surface.
  • the pump housing is in two parts, for example composed of a cylinder housing guiding the pump piston and a storage end cap closing it at the outer end, the germ filter is expediently only attached to one of these two components, preferably to the cylinder housing.
  • the discharge pump 1 has an active substance store, which is otherwise not shown in detail, which is essentially axially symmetrical Pump housing 2, which consists essentially of a gradually narrowing towards the inner end of the cylinder housing 3 and an end cap 4, which is attached to the outer, furthest end of the housing 3 by clip-like snap-in so that it covers the jacket of the Cylinder housing 3 in the area of the associated end overlaps both on the inner and on the outer circumference.
  • a pump piston 6 is slidably guided with a piston sleeve 7 made of elastic material, which tapers in the manner of a truncated cone to the outer end of the housing 2 and tapers with it inner end is guided in the manner of an annular sealing lip on the track 5.
  • a piston sleeve 7 made of elastic material, which tapers in the manner of a truncated cone to the outer end of the housing 2 and tapers with it inner end is guided in the manner of an annular sealing lip on the track 5.
  • an elastic compression sleeve 8 which is formed in one piece therewith, the outer end of which is fastened to a piston tappet 9 by annular clamping.
  • the piston tappet 9 which protrudes from the cap 4 for manual operation, has a discharge channel 11 for the active substance which extends from the pump chamber 10 receiving the piston 6 to its outer end, the discharge channel 11 through the interior of the piston sleeve 7 and the Compression sleeve 8 leads.
  • a discharge valve 12 is provided, the annular movable valve closing part of which is formed by a valve lip projecting annularly over the inner surface of the component which forms the piston sleeve 7 and / or the compression sleeve 8.
  • the valve seat 14 for this valve closing part 13 is formed by the Kollens tappet 9 and is flared at an obtuse angle towards the inner end of the discharge pump 1.
  • the valve closing part 13 is pressed against the valve seat 14 by the axial prestressing of the compression sleeve 8.
  • the end Trag valve 12 can be designed as a pressure relief valve or, as in the illustrated embodiment, as a mechanically opening valve which is opened at the end of the pump stroke by running the piston sleeve 7 onto a stop shoulder 15 of the pump housing 2.
  • the pump piston 6 is loaded by a prestressed return spring 16 arranged in the cylinder housing 3, which is supported on the one hand at the inner end of the piston rod 9 and on the other hand in the area of an inlet valve 17 designed as a check valve for the pump chamber 10 relative to the pump housing 2.
  • the discharge pump 1 is expediently arranged on or in the storage indicated by dash-dotted lines at 20 in such a way that the pump housing 2 engages in the neck 21 of the storage 20 following the end cap 4 and one provided on the cap 4 and above it
  • the circumferential projecting annular fastening flange 22 is sealed against the outer end face of the neck 21.
  • a discharge channel 23 leads through the discharge pump 1 as a ventilation connection between the interior of the reservoir 20 and the outside atmosphere.
  • the ventilation channel 23 is formed between the outside atmosphere and a ventilation valve 24 located inside the pump housing 2 in a filter inlet chamber 25 by an annular gap which is located radially on the inside is delimited by the outer section of the piston tappet 9 and the compression sleeve 8 adjoining it and radially on the outside by an inner sleeve 26 which that engages in the cylinder housing 3 section of the end cap 4.
  • the wall 27 of the housing 3 is penetrated by an axially slot-shaped passage opening 28, which establishes the ventilation connection to the inlet chamber 25 and the interior of the store 20.
  • the movable valve closing part 29 of the ventilation valve 24 is formed by a portion of the piston sleeve 7 or the compression sleeve 8 which is enlarged in the shape of a truncated cone on the outer circumference against the pump chamber 10, this portion lying essentially in the same axial area as the valve closing part 13.
