Foam, spray or atomizer nozzle

A nozzle for foaming, spraying or misting a first media in the form of a liquid by means of at least one pressurized second medium in the form of a gas, the nozzle comprising:

• a) an outlet for a foam or spray mist;
• b) a housing comprising:
• i) a replaceable annular component arranged in said housing;
• ii) a plurality of radially inwardly directed ducts for feeding the second pressurized medium arranged obliquely with respect to a main flow direction of the first media mixed within said replaceable annular component, wherein said plurality of radially inwardly directed ducts are arranged in two separate groups integrated in said annular component, said two separate groups comprising a first group and a second group, wherein said radially inwardly directed ducts of said first group are aligned obliquely in a direction opposite said radially inwardly directed ducts of said second group and obliquely with respect to said main flow direction;
• iii) a first inlet for feeding the first media;
• iv) a first inlet duct arranged in the housing for applying the at least one pressurized second medium to said first group of radially inwardly directed ducts;
• and
• v) a second inlet duct arranged in the housing for applying the at least one pressurized second medium to said second group of radially inwardly directed ducts;
• wherein the at least one pressurized second medium may be applied to said first and said second groups of radially inwardly directed ducts simultaneously or alternatively.
