  • Another advantage is the measure that the extending coaxially and in extension of the pump chamber Section of the liquid supply channel as a tubular, insert piece loaded by the compression spring is designed. Then it is proposed that the end face of the pump piston a Well has a free entry into the pump chamber protruding end of the insert. This tubular end conveys the batch to be dispensed Direction of the mouthpiece nozzle, passing through the annular space Environment of the uncased section of the Insert piece.
  • An even more independent design Significance is that the valve assembly is made on the insert, so that a Inlet valve and an outlet valve as the insert Molded soft parts formed in the combined injection process are.
  • the basic body of the insert itself is designed relatively harder, the soft parts are rubbery. Such a measure reduces the number of parts and simplifies assembly.
  • a bottle 1 is shown in the standing position.
  • the Bottle interior 2 contains sprayable liquid 3.
  • a pump 4 is used for spraying. It is on the neck 5 of bottle 1 put on. That can be done in screwdriving Be realized, also by bouncing or using a bayonet lock.
  • a reversible assignment of the pump 4 a so-called Trigger pump, before.
  • the actuator of the pump 4 is a hand lever 6. It has two arms and is oriented horizontally Axle journal 7 pivotally mounted. Physically can it is a pair of stub axles that root in a housing 8 of the pump 4 and freely in Shafts of the same protrude. The latter have a pivoting effect on the hand lever 4.
  • the pump housing 8 is made of plastic. It takes into account the incorporation of a piston / cylinder unit.
  • the pump cylinder is designated 9. He receives a double-pot-shaped pump piston 10. The is from the right end 11 of the pump cylinder 9 inserted into the pump cylinder 9 and is spring loaded in the outward direction. It is a compression spring 12. The pots of the pump piston 10 open in opposite directions. You have a common one Cross the floor.
  • the compression spring 12 is with its one piston side End in one of the pots, more precisely in a pot-forming one Well 13 of the pump piston 10.
  • the one Pump chamber 14 facing end face 15 of the pump piston 10 can be overlapped axially overlapping by with pump actuation in the central recess 13 an end 16 of an insert projecting in this direction E can be immersed with a limited number of stops.
  • the Pump piston 10 closes, overflowing end 16. This end 16 takes the other end of the compression spring 12 touching and captivating. This is what a Ring collar 17.
  • the annular channel-forming tube section 21 has one smaller clear diameter or cross section than the upstream pump chamber 14.
  • the corresponding Wall jump leads to a designated 23 Bulkhead.
  • Whose pump chamber 14 facing Ring flank provides a valve seat surface 24. With this an inlet valve V1 cooperates. The latter extends just behind the spring abutment of the compression spring 12 ring collar 17 and is formed by this Compression spring 12 held in the locking system to 24. So is the insert in the direction of its insertion position cushioned by a stroke.
  • Axially spaced from the ring-shaped inlet valve V1 extends an exhaust valve V2.
  • the latter closes, the mouthpiece nozzle 18 closer than that Inlet valve V1, on this and is also in the form of an annular disk designed. It sits in one opposite 21 somewhat enlarged pipe intermediate section 25 of the pump housing 8. Here too is the clear diameter meant.
  • the end region of the mandrel facing the swirl chamber 19 22 has ribs on the inside of the tube which leave peripheral longitudinal channels 26 between them so that the liquid 3 enters the swirl chamber 19.
  • a radial outlet end 27 opens up into the pump chamber 14 extending portion 28 one Liquid channel 29.
  • the insert E designed accordingly tubular.
