Abstract
An assembly for spraying a liquid comprises a dispensing head (3) fixed onto a container (2). The dispensing head (3) includes two chambers (34, 35) aligned on the same longitudinal axis and contained in a single body (33). The two chambers are separated by a transverse partition (39). The first chamber (34) is closed by a piston mounted so as to slide with respect to a rod (7). The rod (7) carries, at its end opposite the piston (6), a point (71) whose seat is the opening (37) for communication between the first chamber (34) and the second chamber (35), which opening is made in the partition (39). The first chamber (34) is connected to the container (2) by a non-return valve (9). The second chamber (35) is provided with a spray nozzle (11) which, being located on a fixed wall, is itself fixed.
