The cylinder is mounted removably on the frame of the filling station, in a position located above the position for receiving the aerosol receptacle, by a jack driving a piston with recipricatory movement in the cylinder to cause liquid contained in the cylinder to pass through the valve in engagement with the cylinder. The filling station extends above a washing and drying station having at least one reservoir of washing fluid provided in its upper portion, extending above the maximum level of the fluid in the reservoir, with elements for suspending the cylinder so as to ensure draining.
