Abstract (en)
Improvements in valves for the atomized delivery of liquids contained under pressurized gas, such as nitrogen, in cans or other containers, comprising a body and a valving member and in which liquid is mixed with gas in a chamber (12, 12A) positioned upstream of the valving member (11, 11A) which controls the delivery of the atomized product and moves within said chamber, said improvements comprising premixing the liquid and gas in a premixing chamber (21, 21A) positioned prior to that (12, 12A) in which the valving member (11, 11A) moves and separated therefrom by a nozzle or narrow passage (20, 20A) having a cross-section substantially less than that of said chambers. <IMAGE>
