ABSTRACT:
A dispenser device is described having a metering chamber provided with inlet and outlet ports. Independently mounted, angularly disposed valves are associated with the ports. An activator comprising a cam wheel driven by an electric motor operates the valves in predetermined sequence through valve control arms respectively associated with each of the valves. The valve control arms are pivotally mounted and co-operate with an extension of the valve stem extending externally of the metering chamber. The electric motor is actuated by a button operating through a lever so as to close a switch. The cam wheel includes a switch cam track which holds the switch closed for a full cycle of the dispenser. Also a deactivating cam track is arranged to displace the lever so that manipulation of the button cannot effect the dispenser operation once the cycle has been initiated.
