Abstract

Apparatus for transferring metered quantities of a flowable bonding agent from a tank into a mixer of a sand core making machine has an upright tubular vessel into which the bonding agent is drawn from the tank by a suction pump and a pressure pump which transfers the accumulated bonding agent from the vessel into the mixer. The vessel contains a float which cooperates with sensors serving to generate signals for actuation or deactivation of the pumps and/or valves in the conduits connecting the vessel with the tank, mixer and the pumps. The bonding agent is kept out of contact with the pumps and out of contact with the valves in the conduits connecting the vessel with the pumps.
