Abstract

The unit consists of a storage chamber, formed as a melting chamber, for the liquids; a discharge a conduit; and a valve. During the suction stroke of the pump, the valve connects it to the chamber, while during the delivery stroke, it connects the pump to the discharge conduit. The volumetric stroke of the pump is larger than the largest proportioned amount of liquid to be discharged. After the discharge of the liquid, the valve may be switched from the second into the first position. The unit discharges proportioned amount of liquids in the manufacture of moulded polystyrene, using certain amounts of liquid isocyanate.
