Definitions

  • the invention relates to an atomizer pump with a container connection, in which, by actuating the pump piston which can be displaced in a housing bore, a ventilation connected to the atmosphere is released or closed to the container connection.
  • Atomizer pumps of this type are used for conveying liquids from containers and for dusting or spraying a metered amount of liquid in each case.
  • These atomizer pumps which can be placed on the container with their housing, are actuated mechanically from the outside via lever handles or the like, which act on a wide variety of piping devices.
  • a certain amount of liquid is produced from the esseu-me sucked in, where there is atmospheric pressure in the container.
  • the sucked-in liquid is pressed by renewed pressure on the pump piston via a liquid feed channel to a spray nozzle, in front of which, for example, a swirl chamber can be arranged.
  • the container is ventilated in order to restore the atmospheric pressure in the container.
  • Atomizer pumps of various types which can be screwed onto the container, for example with a container connection piece, an intermediate piece and a union nut. It is known to act via the pump actuating lever and corresponding linkage on the elastically sealing neck of the intermediate piece, which is pressed off its sealing surface with each actuation, so that ventilation to the container is released. It is also known to override an aeration leading to the container connection with the pump piston in a corresponding bore in the housing. In both cases it is necessary to control the ventilation in order to prevent liquid from inadvertently escaping through the ventilation when the container with the atomizer pump placed thereon is appropriately reversed. The ventilation must therefore be sealed off from the outside.
  • the known ventilation actuations additionally require parts or bore channels.
  • the object of the invention is to provide the necessary ventilation above the at an atomizer pump of the type mentioned To simplify the design of the tank connection.
  • such an atomizer pump is characterized in that a lip seal is provided on the pump piston or its shaft in the form of a ring, which sealingly rests on a smooth section of the housing bore before the piston is actuated, and that when the piston is moved in the pumping direction, a complete or partial one The annular gap between the lip seal and the inner wall of the bore is opened.
  • a housing bore that widens to the side of the container connection and an open connection from the housing bore to the container connection can be provided.
  • This housing bore should preferably expand conically in sections, the opening angles of the conical sections being different
  • 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.
  • a further embodiment of a nebulizer pump according to the invention is characterized in that parallel spacing webs are formed in the housing bore in the longitudinal direction, on which the lip seal slides, whereby a ventilation connection is released from the atmosphere to the container connection.
  • the oblique, ring-shaped lip seal abuts the inner ring collar of the housing bore when the piston moves back under pressure, so that the piston cannot be pulled out of the bore.
  • FIG. 1 shows a longitudinal section through an atomizer pump in the closed position of the pump piston
  • 2 shows a representation corresponding to FIG. 1 in the actuating position of the pump piston
  • FIG 3 shows a longitudinal section through another embodiment of an atomizer pump in the closed position of the pump piston.
  • 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 BeeLter.
  • a first check valve generally designated by the number 2
  • the valve 22 the valve 22 and the spring 7 acting against the ball, this spring being supported on the pump piston 5.
  • the pump piston 5 protrudes 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 is on the outside put on with the guide 91.
  • This hollow piston shaft 51 is connected to a channel 13 on the pressure piece 9.
  • the channel leads to a swirl chamber 1 in the opening of which the atomizer nozzle 14 is inserted.
  • liquid becomes from the narrowing pump cylinder 15 via the open check valve 4 through the hollow piston 5 to the channel 13, from there to
  • the pressure piece is raised via the pressure spring 7 when the pressure piece 9 is relieved.
  • the pump piston 5 slides back
  • a lip seal 54 which is formed on the outside of the piston skirt 51 in the form of a ring, slides out of the position according to FIG. 2 into the sealing position according to FIG. In the closed position, the lip seal 54 lies sealingly against the wall of the housing bore section 16 a.
  • the housing bore 16 is thereby closed off from the end opening 19.
  • the lip seal 54 first reaches the stepped conical region 16b of the housing bore 16 and then the region 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 & es 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 outside, is formed concentrically in the direction of the duct 13 ′
  • the pump piston 5 ' is extended outwards with a shaft 51', on which a lever handle 52 'sits, which is guided parallel to the fc se of the piston ⁇ .
  • the pump recess 16 'or the bore 17' provided therein is open towards the lever handle 52 ', ie it is connected to 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.
