ABSTRACT:
An apparatus (10) for proportioning and mixing liquid components of a solvent has a chamber (12) with a rotatable piston (24) mounted in the chamber. The chamber has a plurality of liquid component inlets (18, 20 and 22). Rotatable piston (24) has a notched portion (30). Relative lengths of time the notched portion (30) is opposite the inlets (18, 20 and 22) determine the proportion of liquid components supplied at each inlet port (18, 20 and 22) in the solvent mixture. Rotation of the piston (24) in the chamber (12) mixes the liquid components introduced through the inlet ports (18, 20 and 22). Stepper motor (32) is controlled by microprocessor (52) driven control system (50) to position the notched portion (30) at the inlet ports (18, 20 and 22) for variable lengths of time.
