FOAM-FORMING ASSEMBLY, COERCIBLE FOAM-FORMER AND DISPENSER Russian patent published in 2012 - IPC B05B7/00 B05B11/04 

FIELD: process engineering.

SUBSTANCE: invention relates to foam-forming assembly and foam dispenser, in particular, to pumpless coercible foam-former. Foam-forming assembly incorporates circular fluid discharge channel. Air channel outlet and dispenser channel inlet are located on circumference of imaginary circle. Circular sealing surface is arranged between fluid channel circular outlet and that of air channel and/or dispenser channel inlet. Valve body comes tightly in contact from that surface in initial position. In dispensing, valve body gets separated from sealing surface to communicate, simultaneously, the air channel outlet, fluid channel outlet and dispenser channel inlet. In foam-forming assembly, taper is located in dispenser channel, preferably, upstream of dispenser channel or sieve element arranged in the latter. Coercible foam former has air channel and fluid channel communicate with coercible tank for fluid and air. Fluid and air channels of dispenser communicate with pressurised fluid and air sources.

EFFECT: better foam mixing.
