A lever (1) placed on a laminar body has on it internal face a hollow elongated prismatic body whose ends are curved and slightly inclined with a hair pin cavity (1') having a bedded reflex U . Near the centre of the lever external face is a cylindrical lug which slides up from the bottom on a fluting in the lever body. Above this lug is a horizontal spring whose ends are each fixed to a lug located at the ends of the lever. Three meshing toothed wheels (6,9,9') are located in cascade in three superposed planes. The largest wheel (6) has on its inside face an eccentric hollow cylinder (6'). A toothed cylinder (8') is rotated by meshing with the lower wheel (9'). ADVANTAGE - Allows fitting to aerosols having different sizes of valve.
