Abstract
The invention relates to a nozzle for foaming, spraying or misting in particular liquid, first media by means of at least one pressurized, second, in particular gaseous or gas-containing, medium, an outlet for the foam produced being arranged on the nozzle and the nozzle (1) comprising a housing (4) in which at least one radially, obliquely, tangentially, obliquely tangentially or perpendicularly tangentially inwardly directed duct (5, 5′) for feeding the second medium and a first inlet (6) for feeding the media to be foamed are provided.
Claims62
A nozzle for foaming, spraying or misting in particular liquid, first media by means of at least one pressurized, second, in particular gaseous or gas-containing, medium, an outlet for the foam or spray mist produced being arranged on the nozzle, wherein the nozzle (1) comprises a housing (4) in which at least one radially inwardly directed duct (5) for feeding the second medium and also a first inlet (6) for feeding the medium to be foamed are provided.
The nozzle as claimed in one of the preceding claims, wherein an annular chamber (9), which is adjoined by the inwardly directed ducts (5), is provided between the annular component (7) and housing (4).
The nozzle as claimed in one of the preceding claims, wherein the first inlet (6) and the outlet (2) are arranged opposite each other in the main flow direction (26).
The nozzle as claimed in one of the preceding claims, wherein the ducts (5) are oriented substantially counter to the main flow direction (26).
The nozzle as claimed in one of the preceding claims, wherein the ducts (5) are oriented substantially in the main flow direction (26).
The nozzle as claimed in one of the preceding claims, wherein the ducts (5) are configured as round bores.
The nozzle as claimed in one of the preceding claims, wherein the annular component (7) can be turned in the housing (4).
The nozzle as claimed in one of the preceding claims, wherein differently shaped annular components (7) can be used in the housing (4).
The nozzle as claimed in one of the preceding claims, wherein the annular component (7) is sealed off at an inner wall of the nozzle.

The nozzle as claimed in one of the preceding claims, wherein a heating apparatus is provided.
The nozzle as claimed in one of the preceding claims, wherein a UV emitter is provided.
A method of foaming an in particular liquid, first medium by means of at least one pressurized second medium, wherein the second medium is introduced in an annular component through an at least radially inwardly directed duct, and the first medium fed in through another inlet is foamed.
The nozzle as claimed in one or more of the preceding claims, wherein the annular component (7) is designed as a separate replaceable part, the flow connection comprises at least one duct (5) in the annular component (7), and the duct (5) runs obliquely with respect to the main flow direction (26).
The nozzle as claimed in one of the preceding claims, wherein the annular component (7) is arranged substantially between the two housing parts (4″, 4′).
The nozzle as claimed in one or more of the preceding claims, wherein the annular component (7) is replaceable, the ducts (5, 5′) are arranged obliquely with respect to the main flow direction (26) of the media mixed within the annular component (7), and the ducts (5, 5′) are arranged in two separate groups in the component (7), the ducts (5) of one group being aligned obliquely in the direction opposite to the ducts (5′) of the other group and obliquely with respect to the main flow direction (26) and it being possible for the groups of ducts (5, 5′) to have at least one pressurized medium applied to them, alternatively or simultaneously, via two separate inlet ducts (8, 8′) arranged in the housing parts (4′, 4″).
The nozzle as claimed in one or more of the preceding claims, wherein the component (7) is designed mirror-symmetrically with respect to its duct arrangements.
The nozzle as claimed in one or more of the preceding claims, wherein the ducts (5, 5′) open radially, tangentially, obliquely tangentially or perpendicularly tangentially into the duct (20) of the component (7).
The nozzle as claimed in one of the preceding claims, wherein the annular component (7) has at its ends two circumferential annular chambers (28, 28′), whose open groove outer sides (29) are substantially aligned with the inlet ducts (8, 8′).
The nozzle as claimed in one of the preceding claims, wherein the bottoms (30) of the annular chambers form a wedge face, which run from the groove outer sides (29) of the component (7) obliquely toward the inlet openings (30′) of the ducts (5, 5′).
The nozzle as claimed in one of the preceding claims, wherein the axes of the ducts (5, 5′) form an acute angle α with the main flow direction (26).
The nozzle as claimed in one of the preceding claims, wherein the first housing part (4″) has an outlet duct (2) that is substantially aligned with the duct (20) of the component (7), and the second, identical housing part (4′) has an inlet duct (6) that is substantially aligned with the duct (20) of the component (7).
