Definitions
- Pressure sprayer are both a liquid and a gas, usually air, pressurized.
- the liquid later forms the desired foam and the gas serves as a blowing agent for the production of the foam.
- the Foaming element is a body of a porous
- Foam element of the desired foam is Foam element of the desired foam.
- This foam is then passed through a nozzle that can be configured as a round nozzle or as a flat nozzle.
- the nozzle does not contribute significantly
- Foaming but mainly serves the Verteilu of the foam.
- Pressure sprayer produced foam more or less solid or dry, or be more or less moist or liquid.
- the invention is therefore based on the object, a
- This task is used in a foaming unit for
- Liquid comprising a slider
- Foaming element an inlet for a mixture of gas and liquid and an outlet, wherein the
- Foaming element is arranged hydraulically between the inlet and the outlet, achieved in that an active volume of the Verschaumungselements is adjustable.
- the foaming element which is located in the foaming unit, does not have to be replaced or changed in size in order to change the consistency of the foam. Rather, by covering the foaming element in regions, the length of the flow path of blowing agent and liquid can be controlled by the foaming element. Depending on the length of the flow path, a more or less large area of the VerDumungselements is activated or
- Foaming element changes depending on the relative position of a control edge and an end face of the VerDumungselements.
- Foaming element must take, lengthen or shortened. As a result, the volume involved in the foaming of the liquid (active volume) of the
- Foaming element enlarged or reduced.
- One way to control the active volume provides a housing, wherein the housing and the slider are relatively displaceable. As a result, the distance between the end face and the changes
- Control edge in the manner according to the invention, when said components are moved relative to each other.
- the housing has a receptacle for the VerDumungselement.
- this cap-like receptacle is an end of the
- Foaming element is added and held there. It can also be held in this receptacle by spring force. This means that one end of the
- Foaming element is always disabled and the Liquid and the propellant gas on a side surface of the Verschaumungselements enter into this and on an opposite end of the receptacle of the
- Control edge are part of the housing, can by moving the slider and consequently also the
- Foaming element the active volume can be controlled.
- control edge on the slider and push the slider more or less far in VerDumungselement. This also allows the active volume of the VerDumungselements be controlled.
- Embodiments should not be associated with it. Depending on which materials
- Foaming element and the housing are made, it is conceivable that the Verschaumungselement is fixed in the manner of a press connection in the receptacle. It is also possible that a compression spring, which is arranged between the slide and the Verschaumungselement, the
- Foam element presses into the receptacle of the housing.
- a device for adjusting the active volume which adjusts the relative position of the slide and the housing when it is actuated.
- This device may be operated by a thumbwheel cam mechanism.
- the thumbwheel is rotatably mounted on the housing and has a backdrop, with one on the slide
- Casing cooperates, wherein the slider has a tubular portion having a through hole and a control edge, set by turning the sleeve nut, the desired change in the relative position of the control edge and end face of the VerDumungselements.
- the inlet via which the propellant and the liquid are brought into the foaming unit, into the housing or into the slide.
- both arrangements are equivalent. It is ultimately a question of the available space and the
- the foaming element may be a commercial one
- Be filter element made of an open-pore material.
- Felt, nonwoven fabric, synthetic fabric and / or metal fabric have proved to be particularly suitable. Also combinations of these or other materials are possible. In general, one can say that the pressure loss caused by the material should be as low as possible.
- the foaming element is designed as a hollow cylinder.
- Foaming element is adjustable. This can be achieved most easily with prismatic bodies (cylindrical rollers, hollow cylinders). The adjustment range of the foam unit can be extended if a VerDumungselement consists of areas of different porosity. That's the way it is
- Foaming element has a first region with a first porosity and to this first region, a second region of a different material or of the same material but with a different porosity is connected.
- the desired material combinations and porosities must be adapted to the application and in particular the liquid to be foamed.
- the object of the invention is also by a
- Sprayer comprising a pressure vessel, a
- the sprayer is preferably a pressure sprayer with manual or motorized pressure pump.
- FIG. 2a) and b) is a further schematic representation of an inventive
- Figure 7 shows the embodiment according to the invention
- Figure 8 is an isometric view of a
- Figures 9 and 10 are longitudinal sections through another
- Figure 18 is a view of a slider with
- the foaming unit comprises a Slider 4, on which with the aid of a union nut 20, a spray nozzle 1 is arranged.
- a through hole 24 is formed, in which a
- the right in the figures la) and lb) end of the through hole 24 has the function of a control edge and is provided with the reference numeral 25.
- the foaming element 6 is made as a cylinder of a porous material. It can also consist of several sections of different porosity and / or
- the VerDumungselement 6 is sealingly guided in the bore 24. Because a hole 24 having a circular cross section can be most easily manufactured, the foaming member 6 is formed as a (full) cylinder.
- a pressure chamber 26 In a pressure chamber 26 are a propellant and a liquid to be foamed. Both are not shown.
- the foaming element 6 has at the in the
- annular region 32 is present between the housing 7 and the right in the figures la) and b) the end of the slider 4, an annular region 32 is present. This annular region 32 is delimited by the control edge 25 on the one side and by the housing 7 or the receptacle 28. It effectively provides the inlet for the propellant and the liquid in the foaming element 6.
- Propellant always choose the path of least resistance, the active part, that is, the part of the VerDumungselements 6 flowed through by blowing agent and liquid, in first approximation proportional to the length L.
- the length L is equal to the distance between the control edge 25 and the end face 30.
- L in this embodiment denotes the length with which
- Foaming element 6 projects into the receiving bore 24.
- the path of the propellant gas and the liquid is indicated by the VerDumungselement 6 with the reference numeral 8.
- la is the VerDumungselement 6 very far the through hole 24 immersed, because the slider was moved correspondingly far to the right.
- the Relative movement of the housing 7 and slider 4 is indicated by a double arrow (without reference numeral).
- the region 32 between the housing 7 and the right end of the slide 4 or the passage opening 24 in FIG. 1a) is relatively small. This relatively small entrance surface for the
- Foaming element 6 resulting foam.
- the essential quantity which determines the consistency of the resulting foam is the already mentioned length L.
- the length L is relatively large and as a result, the active volume of the
- Foaming element 6 also relatively large. In the context of the invention, at least the part of the foaming element 6 between the
- Control edge 25 and the end face 30 denotes.
- the region 32 of the VerDumungselements 6 still contributes something to the active volume of the VerDumungselements.
- the length L in the figure lb) is much smaller than in the figure la). Accordingly, the active volume of the VerDumungselements 6 is much smaller. As a result, the foam that is in the
- Foaming unit is made in the position of the Verschaumungselements 6 shown in Figure la) relatively dry and solid, while at the position of the
- Foaming element 6 according to Figure lb) is relatively fluid and less solid.
- Foaming element 6 is not necessarily linear. However, there is a direct relationship to the effect that with increasing immersion depth L of the VerDumungselements 6 in the passage opening 24 under otherwise identical conditions, the resulting foam is firmer and drier. In other words, by moving the foaming element 6 relative to the control edge 25, the consistency of the resulting foam can be controlled.
- Figures 3 and 4 show this embodiment in a view from above and a section along the line A-A at a low active volume of
- Foaming element 6 The same embodiment is also shown in Figures 5 and 6 in a plan view and in a sectional view with a large active volume of the VerDumungselements. 6

- the housing 7 is shown more fully in FIGS. 4 and 6 than in the exemplary embodiment according to FIGS. 1a) and b).
- the housing 7 has an inlet 36 at its right end in FIG. This inlet 36 or this inlet opening is largely invisible. However, it is clear by the arrow 8 that, the mixture of Propellant gas and liquid from the right passes through the aforementioned inlet opening in the housing 7.
- the housing 7 has a cup 38 in which the receptacle 28 for the VerDumungselement 6 is located.
- the cup 38 is connected to the actual housing 7, that a hydraulic connection between the inlet 36 of the housing 7 and the pressure chamber 26 is made. This happens because of the fact that
- Scope of the cup 38 openings are formed, which release the indicated by the arrow 8 flow path from the inlet 36 into the pressure chamber 26.
- Liquid is to flow from the space 26 into the outlet 34 through the active volume of the foaming element 6.
- Foaming element 6 minimally, similar to that shown in Figures lb) and 2b). For reasons of clarity, it has been omitted to enter the length L and the region 32 in FIG. In the figures 5 and 6, the same embodiment of a VerDumungsaku is shown, wherein in the position of the slider 4 shown in Figures 5 and 6, the active volume of the Verschaumungselements is a maximum, because the Verschaumungselement 6 as far as possible in the
- the cam mechanism comprises a pin 13 which is formed on the slider 4, and a setting wheel 10 which is rotatably mounted on a bearing pin 11, which in turn is part of the housing 7.
- the thumbwheel 10 is mounted by being clipped onto the clip 12 as a bearing pin from above.

- Foaming element 6 adjusted and as a result also set the consistency of the foam.
- the sleeve nut has the function of the "slider" 4th
- the foaming element 6 is designed as a hollow cylinder and pushed onto the coupling element 5.
- the end face 30 is therefore annular.
- Coupling element 5 can be releasably connected (for example by a nut 2) or - after successful assembly of the sleeve nut 46, the VerDumungselements 6 and the sealing rings 16 - inextricably linked.
- the slider 4 and the control edge 25 are integrated into a sleeve nut 46.
- the sleeve nut 46 is on the part 7.2 of the housing
- the sleeve nut 46 is formed as a tubular portion having a through hole 48, the the foam element 6 receives sealingly but axially displaceable. At the right in Figure 9 end of the tubular portion, the control edge 25 is formed.
- sealing rings 16 are provided between housing 7 and sleeve nut 46.
- the inlet 36 is integrated into the housing 7. Also in this embodiment, there is a hydraulic connection between the inlet 36 and the space 26. From the space 26 reach
- FIG. 12 shows a section along the line C-C in FIG. 11 at a low active volume of the FIG
- Foaming element 6 The same exemplary embodiment is likewise illustrated in FIGS. 13 and 14 in a plan view and in a sectional illustration with a large active volume of the foaming element 6. In FIG. 12, the foaming unit is shown in section, along the line CC from FIG. 11.
