said first valve being in its said closed position when said valve actuator is in its said lower position;
said valve actuator, when in its said upper position, engaging said normally closed valve to open the same whereby liquid in said container may flow downwardly therefrom through said valve and through said flow control assembly;
said valve actuator having a cam lever secured thereto which is movably positioned within a cam track.
8. In combination:
