  • the pawl (74) and the automatic working Valve with ball (70) and spring (71) can (analogous to the illustration in Fig. 2) a Trigger button containing the atomizing nozzle, and with the when pressing manually open the valve in front of the nozzle. This shutter button is at the top of the Atomizer attached.
  • collapsible bag (63) can be a non-deformable sealed Container to be used with an automatically operating vent valve as well with a projecting into the container dip tube, optionally in the form of a Coiled pipe, provided.
  • the seal of the hollow piston against the cylinder by means of the upper edge (56) of the Stopfens can be replaced by an O-ring, which is in a groove in the lower end of Cylinder at the point (80) is mounted.
  • this may be the hollow piston containing component (55) to be connected to the lower housing part, and the cylinder with the space (57) can with respect to the lower housing part (51) in the axial direction be movably arranged.
  • a multi-toothed pawl be provided, which is constantly engaged during clamping of the coil spring.
  • a screw-thrust gear can be used that can be rotated more than 360 degrees can. This can be used to tighten the coil spring by turning the two Reduce housing parts sufficiently against each other manually applied force.
  • Fig. 5 shows a cross section through a nozzle with outside mounted in front of the nozzle Ball as an impact body.
  • the pressurized fluid will escape from the nozzle orifice (104) in the form of a closed jet (102) ejected onto a baffle (106).
  • the liquid passes into the atomized jet (107).
  • Fig. 6 shows a cross section through a nozzle with two mutually inclined Nozzle channels.
  • the two liquid jets escaping from the nozzle bounce outside the nozzle on each other.
  • the pressurized fluid will be out of the two Nozzle openings (108) and (109) in the form of two closed beams (110) and (111) pushed out. Both beams collide at the point (112). It goes the Liquid in the atomized jet (113) over.
  • a swirl nozzle is shown in the form of a vortex chamber.
  • Fig. 7 a shows the vortex chamber nozzle in the view from its inside with the cover plate removed.
  • FIG. 7 b shows a longitudinal section through the vortex chamber nozzle along the line A - A in FIG Fig. 7 a and parallel to the nozzle axis.
  • Fig. 7c the area around the nozzle channel shown enlarged.
  • the nozzle channel (122) is in the axis of Whirl chamber nozzle arranged, the liquid to be atomized by, for example three channels (123) tangentially into the vortex chamber (124) passed.
  • the axes of the channels (123) pass the axis of the nozzle channel.
  • the channels (123) are compared to Nozzle channel (122) shown enlarged.
  • the cover plate (125) for the vortex chamber and the Contains channels in the region of the outer end of the channels (123) each have an opening (126), through which the liquid enters the channels (123).
