Abstract:
The application relates to a method for producing compressed air foam for fire-fighting, wherein the method comprises the following steps: supplying a mixture of water and foaming agent via a supply line ( 12; 22 ) in a mixing chamber ( 11; 21 ) of a foaming line ( 10; 20 ), wherein a regulating device ( 14; 24 ) is disposed in the supply line ( 12; 22 ), by means of which a volume flow of the mixture can be regulated, suppling compressed air via a compressed air line ( 13; 23 ) in the mixing chamber ( 11; 21 ), wherein a further regulating device ( 15; 25 ) is disposed in the compressed air line ( 13; 23 ) by means of which a volume flow of the compressed air can be regulated, producing compressed air foam in the mixing chamber ( 11; 21 ) by foaming the mixture of water and foaming agent in the mixing chamber ( 11; 21 ) by means of the compressed air and discharging the compressed air foam from the foaming line ( 10; 20 ) via a mixing pressure regulator ( 17; 27 ) which regulates a mixing pressure in the mixing chamber ( 11; 21 ) into a delivery line ( 30; 40 ), wherein a pressure measuring device ( 31; 41 ) is disposed in the delivery line ( 30; 40 ), which records a pressure in the delivery line ( 30; 40 ) and which, like the regulating device ( 14; 24 ) and the further regulating device ( 15; 25 ), couples to the control device ( 26 ), and wherein the volume flow of the mixture of water and foaming agent and/or the volume flow of the compressed air is regulated by means of the control device ( 26 ) depending on the recorded pressure in the delivery line ( 30; 40 ). The application further relates to an apparatus for producing compressed air foam for fire-fighting.

Claim (Index 3):
The method according to  claim 1 , wherein the volume flow of the mixture of water and foaming agent is regulated discontinuously whereby graduated volume flows are set by means of the control device depending on the recorded pressure in the delivery line.
