  • the valve 46 is designed as a continuously adjustable valve, so that the quantitative ratio between water to be sprayed and additive to be sprayed can be adjusted.
  • an operating part 47 is on the top of the handle section 2 provided that is connected to the valve 46.
  • the coupling of the application device described in connection with FIGS. 12 to 15 to the spray device of an iron can be in addition to that previously described Delivery of the additive to the steam discharge may be provided.
  • the conical valve section has a thin-walled servo sealing surface Mistake.
  • a conical recess in the upper end face of the valve section be provided so that a thin-walled section is formed.
  • the valve device is the channel body 17 and the conical valve section harder material than the spring-elastic shut-off element 21 and the adjoining one Sealing surface 20. It is therefore only the area of the valve device that is elastic and soft trained who due to its clamping as a seal or its resilient, elastic or setback behavior requires these material properties.
  • the two different material properties can e.g. in the form of a one-piece valve device realize that in hard-soft plastic injection technology e.g. with materials from two different shore hardness exist.
  • valve section not conical but disc-shaped.
  • Another variant is not a central one Channel provided with a channel body, but there are outflow openings between the then massive channel body and the shut-off element. Then this is useful if no capillary wick should be inserted into the valve device, but the valve device in other devices the valve function or check valve function should exercise.
  • a Tappets can be arranged opposite the solid channel body through which the valve device is movable in an up and delivery.
  • the elastic section of the shut-off element responsible for the axial mobility disc-shaped is shown in FIG. 16.
  • the valve device closes a fluid tank and is with a screw cap on Tank attached press-tight.
  • the shut-off element 62 has no shut-off function here, but instead serves the elastic, axial mobility of the conical valve section 18 sealingly with a counter surface on the container 63, instead of cooperating with the shut-off element. on the shut-off element 62 protruding lugs 61 are formed, the sealing or act as a support to the counter surface of an opposite part.
  • FIG. 17 shows an application of the valve device in which the outer surfaces 64 of the Shut-off element with complementary sealing surfaces 65 of the opposite part work together in a sealing manner.
  • a tappet 66 pushes the valve device into the open position.
  • the ends 66 of the shut-off element can instead of as here and in those previously described Embodiments not only engaging from the inside on the container or the storage cartridge e.g. sealed with a clamping ring 67, but with a correspondingly twisted one Training the container to be attached sealingly from the outside.
  • a corresponding one alternative embodiment is shown in Figure 18.
  • FIG 19a and Figure 19b show a valve device in a tube with a clamping ring is inserted.
  • This valve device opens automatically as soon as a fluid flow presses against the conical valve section.
  • the reverse flow direction of the Fluids on the other hand, automatically locks the valve device because the fluid pressure blocks the conical valve section presses against the sealing surface on the shut-off element.
  • the valve device thus provides a check valve that all sealing connections to the pipe, resilient Sections and opening and closing sections.
  • Figure 20 shows a valve device in a coffee machine, the flow of coffee to the coffee pot only releases when there is a coffee pot underneath a sliding cap 70 on the Valve device is inserted.
  • the valve device is below the coffee filter holder 72 attached.
  • An elevation 71 is formed on the can lid 73, with the sliding cap 70 interacts.
  • Figure 21 shows an application of the valve device as a leak-proof suction valve on a Baby bottle.
  • the functioning of the valve device advantageously corresponds in a similar manner that of a natural nipple, because the simultaneous pressing and sucking on the Outflow opening of the fluid path is released and after use the valve device automatically snaps back into the closed position due to the spring elasticity.
  • the valve device works preferably monostable for this application, whereby the stable state Is in the closed position.
  • By appropriate modification of the valve device e.g. heavier movable spring-elastic shut-off element
  • this valve device can also be used for other drinking bottles, e.g. for bicycles or in Trekking area is usable.
  • valve device can also be used for all personal products, some of them have removable fluid tank, the valve device of the tank only in use in the device (e.g. water purifier, oral irrigator, iron, coffee machine, humidifier, Shaver) opened and automatically when removed to refill the tank is closed.
  • the valve device can be used for containers from which a certain one Dosing quantity should flow, e.g. in the field of hair cosmetics, dispensers of all kinds, pharmaceutical containers, Liquid writing instruments, dosing syringes, body care, dentifrices, sunscreens, since a constant amount is always pre-metered in the cavity 22.
  • the valve device can also be used advantageously in gas cylinders filled with propellant gas.
  • the valve device can also be used for liquid-protected electrical switches of the monostable or bistable states.
