Definitions

  • the invention relates to an atomizer pump with a container connection in which, by actuating a pump piston which is displaceable in a housing bore, a ventilation to the container connection which is connected to the atmosphere is released or closed, wherein, furthermore, an oblique lip seal is provided on the pump piston in a ring shape, which is actuated before the piston is actuated sealingly abuts a smooth section of the housing bore and with its free end edge on an inner collar of the pump receptacle, and which, when the piston is moved in the pumping direction, releases a gap between the lip seal and the inner wall of the bore.
  • Such an atomizer pump is known, for example, from US Pat. No. 4,183,449.
  • the sliding upper part is locked on the relatively fixed lower part by means of the sealing lip which rests against an inner collar in the rest position. Additional locking means can be omitted here.
  • the invention has for its object to improve an atomizer pump in such a way that the lip seal also serves to lock the pump part on the housing body in such a way that a longer service life with regard to the sealing lip can be achieved.
  • a first solution to this problem is that, starting from the sealing section to form an annular gap in the ventilation position, the housing bore is expanded conically in sections, the section farther from the sealing point merging into a cylindrical section of the housing bore, in the area between the lip seal and an annular gap is formed in the bore wall, and the conical section adjoining the conical section delimiting the closed position has a larger opening angle.
  • a second solution to this problem is seen in that in order to form an at least partial annular gap in the housing bore, parallel webs are arranged at a distance from one another in the longitudinal direction and onto which the lip seal can be pushed for ventilation.
  • the inventive design ensures that with one and the same element, namely the oblique sealing lip, the locking and ventilation takes place, whereby a long life of the sealing lip is ensured.
  • the lip seal provided on the pump piston only slides on smooth wall surfaces. Due to its inherent tension, the lip seal lies sealingly against the wall of the corresponding housing bore section in the closed position. If the pump piston is moved, the corresponding lip seal reaches an area due to the conical design of the housing bore, in which an open annular gap is created between the seal and the bore wall. This creates an open connection between the two end faces of the housing bore.
  • the bore is open to the atmosphere from the pressure side. A breakthrough to the container is provided on the connection side.
  • the entire plastic housing of the swirl atomizer pump shown bears the number 1. With an externally molded flange 18, this housing can be attached to a container, not shown, via the cap-like container connection 3. The lower nozzle 11 on the housing 1 protrudes into the container.
  • a first check valve generally designated by the number 2, which consists of a ball 21, the valve 22 and the spring 7 acting against the ball. This spring is supported on the pump piston 5.
  • the pump piston 5 projects into the actual pump cylinder 15 with a lip seal 53 formed in the shape of a ring, which is connected on one side to the nozzle 11 via the valve 2.
  • This pump piston 5 is hollow.
  • a second check valve 4 is provided on the inside, which in turn consists of a ball 41 and the valve seat 55 and the compression spring 8.
  • the pressure piece 9 with the Guide 91 put on.
  • This hollow piston shaft 51 is connected to a channel 13 on the pressure piece 9.
  • the channel leads to a swirl chamber 12, in the opening of which the atomizer nozzle 14 is inserted.
  • the narrowing pump becomes Penzylinder 15 liquid through the open check valve 4 through the hollow piston 5 to the channel 13, from there to the swirl chamber 12 and sprayed through the atomizer nozzle 14 to the outside.
  • Ventilation takes place in this position via the housing bore 16 connected to the atmosphere and through the opening 10 in the region of the flange 18.
  • a lip seal 54 which is formed on the outside of the piston skirt 51 in the form of a ring, pushes itself from the position according to FIG. 2 into the sealing position according to FIG. 1. It can be seen that this housing bore 16 widens conically towards the connection side. In the closed position, the lip seal 54 lies sealingly against the wall of the housing bore section 16a. The housing bore 16 is thereby closed relative to the front opening 19.
  • the lip seal 54 When the piston moves in the direction of the container connection, the lip seal 54 first reaches the stepped conical area 16b of the housing bore 16 and then the area of the cylindrical section 16c in which an annular gap is released between the lip seal 54 and the bore wall, which enables ventilation.
  • the conical housing bore section 16a delimiting the closed position has a smaller opening angle of the cone than the adjoining housing section 16b.
  • the entire plastic housing of the swirl atomizer pump shown in FIG. 3 bears the number 1 '.
  • a nozzle 11 ' is formed, in which the connector 4' is inserted.
  • a cap 3' is placed, with which the housing can be screwed onto a container (not shown).
  • a tubular connector 15 ' protrudes through the tubular connecting piece 4' and the riser pipe 24 'forms the extension downwards.
  • This riser pipe is held in a nozzle 23 ', which in turn is fastened in the duct nozzle 15'.
  • the upper end of this nozzle 23 ' forms the valve seat 22', which forms a check valve 2 'with a ball 21'.
  • the receptacle 16' for the piston pump is provided transversely to the connecting channel 13 '.
  • the open pump cylinder 6' in which the pump piston 5 'is displaceable from the outside, is formed concentrically to the channel 13'.
  • the pump piston 5 ' is automatically pressed into its outer position via the compression spring 7' which is supported in the housing.
  • the pump piston 5 ' is extended to the outside with a shaft 51', on which a lever handle 52 'sits, which is guided parallel to the axis of the piston.
  • the pump receptacle 16 'or the bore 17' provided therein is open to the lever handle 52 'side, i. H. associated with the atmosphere. It is at its other end in open connection with the container connector 4 '.
  • a lip seal 53 ' is formed in a ring shape on the outer end of the piston 5', which, because of its inherent tension, lies sealingly against a smooth sealing section 19 'of the bore 17'. This ring-like lip seal also forms a stop for the piston movement, since in the outer end position it abuts an inner collar 20 'on the pump receptacle 16'.

Abstract

Dans une pompe pulvérisatrice avec raccord de récipient, l'actionnement d'un piston de pompe (5') déplaçable dans un trou de boîtier (17'), sur la tige (51') duquel est prévu en forme de couronne un joint à lèvres (53'), permet la libération ou la fermeture d'une ventilation en liaison avec l'atmosphère pour le raccord de récipient (24'). Avant l'actionnement du piston (5'), ce joint à lèvres (53') est placé de manière étanche contre un segment plat (19') du trou de boîtier (17'). Le déplacement du piston (5') dans la direction de pompage provoque l'ouverture d'une fente entre le joint à lèvres (53') et la paroi intérieure du trou.
