Embodiment Construction

[0040] Identical components have the same reference numerals in all the figures and the same applies for one figure to the other figures accordingly. Significant differences are evident in the description of the figures.

[0041] Figure 1a and Figure 1b A first embodiment of the foaming unit according to the invention is schematically shown. Only the parts necessary for understanding the invention are shown. The foaming unit comprises a slide 4 on which the nozzle 1 is arranged by means of a union nut 20 . In the slide 4 , a passage opening 24 is formed, in which the foaming element 6 is guided sealingly but axially displaceably. like Figure 1a and Figure 1b The shown right-hand end of the passage opening 24 has the function of a control edge and is designated by the reference numeral 25 .

[0042] The foam element 6 is manufactured as a cylinder of porous material. It may also comprise portions of different porosity and / or different materials.

[0043]In this embod...

Abstract

The invention relates to a foaming unit, by which it is possible to adjust the foam produced in a foaming element (6) simply and rapidly in respect of strength and dryness.

Description

Background technique [0001] Foam needs to be generated and applied to objects, surfaces or walls in many fields. Typical applications include cleaning surfaces or using the foam as a release agent, among others. [0002] This foam is produced by pressure sprayers. Such a pressure sprayer is described in detail in EP 2308603A1. In the pressure vessel of a pressure sprinkler, liquid and gas (usually air) are pressurized. The liquid then forms the desired foam, while the gas is used as the propellant for creating the foam. Liquid and propellant (air) are supplied to the foaming element through a suction hose. The foam element is a body made of porous material. When the liquid, along with the propellant, is forced through the porous material with sufficient pressure, the desired foam is produced upon exiting the foaming element. [0003] The foam is then guided through a nozzle which can be designed as a round nozzle or as a flat nozzle. The nozzle does not significantly co...
