ABSTRACT:
Apparatus for the continuous feeding of plural liquids in separate streams of adjustable quantity and ratio, comprises a drive unit that drives a main pump, and that also drives at least one secondary pump. The drive unit has an oscillating or reciprocating movement, and so the pumps are piston pumps or oscillating vane-type pumps. The stroke of the secondary pump or pumps may be selectively shortened without shortening that of the main pump, so as to predetermine the proportions of the liquids to each other. The system is particularly applicable for the feeding of separate streams of synthetic resins by the main pump, and the associated hardeners, catalysts, accelerators or other auxiliary liquids by the secondary pump or pumps.
