Definitions

  • the invention relates to a discharge device according to the preamble of claim 1.
  • a discharge device according to the preamble of claim 1.
  • at least one device for influencing the medium can expediently be provided in the vicinity of the outlet opening.
  • This device can advantageously be a foaming device for foaming the medium.
  • the medium is expediently a conveying or foaming gas, usually air, mixed in so that it is cell-enclosed in the medium, which consists of a volume unit of medium produced mixed or foaming medium has a much larger volume. If the mixing or foaming of the medium takes place relatively far away from the outlet opening, the increase in volume can lead to a considerable increase in the discharge pressure, which is not advantageous for all types of media. This also applies to the foamed medium remaining in the flow paths after the end of each discharge process. Media that have a tendency to defoam, for example have a very low viscosity, can cause that the foam formed collapses again on the way between the foaming device and the outlet opening, that is to say that the medium and the foaming gas are separated again.
  • a conveying or foaming gas usually air
  • a discharge device according to EP-A-0 286 925 has a pressure channel which opens into a merging zone and which is always open to the merging zone at the same width, the flow through this pressure channel being released by opening the merging zone itself.

Since foam often only fully develops to its optimal foam structure on a stretch of the flow path after leaving the device, it is advisable between the device and the outlet opening therefor a correspondingly short dimensioned foam section or the like. provided, which is formed by a corresponding end portion of the outlet channel.
  • the foaming device advantageously has at least one foaming body through which the medium and the foaming gas are pressed together and thereby mixed with one another in a finely structured manner.
  • the foam body can have a large number of finest passages, which may penetrate it in alternating directions, such as e.g. in the case of a porous filter stone, a sieve, a perforated disc or the like, which also contributes to the mixing by swirling.
  • the arrangement of such a foam body is so expedient that it forms the outlet of the foaming device and a smooth-walled foam section of constant internal width is provided between it and the outlet opening, so that the foam once formed is not further, e.g. turbulence caused at edges is separated again.
  • the foaming body or in particular an additional foaming body can also be provided on the inlet side of the foaming device, so that at least one of the substances to be mixed for foaming, preferably the foaming gas, is already digested before being brought together with the other material as a result of being pressed through passages of the type mentioned and can be mixed with this other substance immediately afterwards.
  • the mixing of medium and foaming gas advantageously takes place within a foaming chamber, which expediently has approximately the same width as the channel part following in the flow direction or only a slightly larger width. Furthermore, it is expedient if the internal width of this foaming chamber is in the order of its longitudinal extent or if it is provided in the same axis as the subsequent channel part or the outlet opening. Furthermore, it can be expedient for the foaming process if the mixing chamber essentially inside is free of any built-in parts, so that there are essentially completely free internal cross-sections within its casing, which can at most be penetrated by a single shaft.
  • the invention is further proposed to provide at least one inlet for each of the two substances to be mixed with one another in the area of the foaming device or into the mixing chamber, the one or more inputs for the one substance expediently being essentially radial and the or the Entrances for the other substance are directed essentially exclusively axially, so that the substances are exposed to a very strong turbulence due to the intersecting flow.
  • the respective axial inlet could be directed in countercurrent with respect to the direction of flow in the subsequent channel section, but is expediently rectified.
  • valve axis is expediently at an angle to the central axis of the foaming device, it being possible for the valve to be arranged, for example, within an actuating cap and / or within a pump chamber for the associated substance.
  • a particularly advantageous development of the subject matter of the invention consists in that at least one foam device is essentially formed by a self-contained structural unit which as a whole is essentially on the outside of the discharge device, namely e.g. to be mounted on the discharge and / or actuating head.
  • discharge devices which are essentially identical in construction can be easily equipped with different devices depending on the requirements. E.g. can this device for influencing the medium only by inserting, screwing, snapping, pressing, gluing or the like. be attached.
