Abstract (en)
[origin: DE19802240A1] The dosing system has in a housing two independently functioning flaps of different sizes which are loaded with an adjustable spring force of variable size. Each flap can be fitted with a separate dosing unit. Each separate dosing device has a dosing bush (5) connected to the flap shaft and supporting a coaxial mounted two-part axially displaceable setting cylinder (7). The mixing percentages for the foam can be infinitely adjustable by the setting cylinder which can be adjusted either manually or remote-controlled through pneumatic, hydraulic, electric or electro-automatic means. The spring force on the flaps can be relaxed for water operation and the flaps can be swivelled on to the side of the housing. The flaps can be provided with potentiometers for measuring the rate of flow.
