  • Method for generating a cleaning agent foam, and injector and foam generation system for carrying out the method
    Publication number: 20060234616
    Abstract: The invention relates to a method for generating a cleaning agent foam, in which a chemical is admixed with a cleaning liquid by means of an injector (22) and in addition air is admixed by means of a foaming nozzle (34). To develop the method in such a manner that an effective cleaning agent foam can be generated with a reduced proportion of chemical, according to the invention it is proposed that the cleaning liquid/chemical mixture is fed to the foaming nozzle (34) under a pressure of at least 30 bar. There are also proposed an injector (22) and a foam generation system (10) for carrying out the method.
