Definitions

  • the invention relates to a dosing pump made of plastic for the dosed delivery of liquid and / or pasty Media from a bottle, can or tube-like container with trailing pistons, one promoting the medium Pump chamber connected to the container via a suction valve and as a pump organ forming a pump chamber, has resilient bellows between a dimensionally stable, lower housing part and one telescopically movable, also dimensionally stable upper Housing part is arranged, and wherein the upper housing part has the outlet opening, which via an outlet channel and an outlet valve connected to the pump chamber is, and wherein the bellows with an upper Ring collar sealing an annular wall of the upper housing part encloses that with a smaller in diameter, in provide the displacement piston protruding into the bellows is.
  • Metering pumps of the generic type are known. she are both for the metered output of a single medium as well as for the simultaneous dosed delivery of two different media used, with the output Medium in a connected to the dosing pump or connectable container is housed. There is Dispensers, so-called dispensers, with two separate ones Storage tanks and two dosing pumps that work together can be operated via an operating lever or the like (DE 101 10 888 A1) and those in which two different Media housed in a single storage container are (DE 200 19 540 U1) and by two separate Dosing pumps in different dosing quantities are conveyed to a common outlet opening.
  • the bellows plays functionally the most important role as a pump organ. This too Bellows must be made of plastic as an injection molded part and be able to adjust the restoring force for that after each working stroke, reset to the required Starting position to bring out of the reservoir to suck the amount of medium into the pumping chamber, which was issued during the working stroke. Therefore must the bellows both in terms of its diameter as well as in terms of its axial length and number a certain minimum size of elastic bellows folds exhibit.
  • the displacement piston has however, a central one on its lower end Opening through which the medium to be pumped to the outlet valve or pumped through this to the dispensing opening becomes. That is why it is with these known metering pumps unavoidable that in the upper area of the bellows a remaining one around the displacement piston Air cushion forms. This compressible air cushion can have the consequence that the dosing amounts of the individual Pump strokes are different.
  • the invention has for its object a plastic parts existing, automatically mountable dosing pump of the type mentioned at the beginning with which Output quantities of the medium to be pumped can be precisely metered are.
  • the inventive design of the displacement piston it is ensured that in the upper, i.e. output side End area of the bellows or the displacement piston can no longer form an air cushion and itself the entire cavity of the bellows, i.e. the entire Pump chamber, with the intrinsically incompressible medium that can have a pasty or liquid consistency becomes.
  • the same result large pumping strokes also the same large dosing quantities every pump stroke to the discharge opening and at the Return movement of the bellows out of the storage container be sucked in.
  • the co-dispenser shown overall in FIGS. 1 and 2 has two separate, cylindrical in cross section Storage containers 1 and 2, which are parallel next to each other arranged and through two connecting walls 3 and 4 into one overall cross-sectionally elliptical container housing 5 are connected.
  • Both storage containers 1 and 2 are each with one Provide trailing pistons 6 and 7, the trailing piston 6 in its lowest and the trailing piston 7 in its uppermost end position is shown. During the Use phase should these two trailing pistons 6 and 7, however, the same axial position within the two Take storage containers 1 and 2.
  • the upper end of the container housing 5 is locked with a Base body 12 connected to a pump head 13, the two parallel and one each Reservoir 1 or 2 associated metering pumps 14 and 15 has. These two metering pumps 14 and 15 are each identically constructed and together by an upper one Hood body 18 can be actuated. Both metering pumps 14, 15 each consist of a bellows 29 as a pump organ, an outlet valve 38 and an outlet valve 55. Die Metering pumps 14, 15 are symmetrical about the vertical central axis 21 of the container housing 5 arranged in the pump head 13.
  • the hood body 18 forms the common dimensionally stable upper housing part of both metering pumps 14 and 15 and with an enlarged section 16 of an oval, axially parallel peripheral wall 17 in an also oval Annular wall 19 of the base body 12 guided axially movable.
  • the base body shown as an individual part in FIGS. 9 to 11 12 forms the dimensionally stable lower housing part of the two metering pumps 14 and 15.
  • Ring wall 19 is located transversely to the central axis 21 trending bottom wall 22 with two symmetrical to this central axis 21 arranged suction openings 23rd is provided.
