Atomizer (3) comprising a pump for drawing a predetermined volume of liquid from a container comprising a generally cylindrical chamber (5) in which slides a piston (6), means for linking the chamber (5) to a nozzle (12) for spraying liquid contained in said chamber and means (13) for actuating the piston (6) and compressing the liquid to force the compressed liquid through the nozzle. The atomizer (3) also comprises a spring-loaded bistable valve (14) which opens fully when a predetermined value (P0) of liquid pressure is attained in the chamber and closes fully when the pressure falls below a lesser predetermined value. The atomizer of the invention is suitable for spraying perfume and cosmetic products.
