ABSTRACT:
An apparatus for automatically operating the discharge valve of a pressure container includes a drive shaft driven by an electric motor controlled by a timing device, the shaft being drivingly connected by a belt to a speed reduction unit having a plurality of intermeshing toothed wheels, the last of the toothed wheels having an eccentric which co-operates with a roller provided on one arm of a pivoted elbow lever. Such arm is connected to a spring which urges the lever towards a position where the free end of its other arm presses on the nozzle of a container to actuate such nozzle.
