Abstract
A metering and conveyor arrangement for liquids to be mixed, in which several parallel-connected delivery pumps are actuated by a drive unit. Each liquid is assigned to a pair of delivery pumps. Each pair consists of two piston pumps alternately performing an intake and a discharge cycle. The pumps are moveable relative to each other, as well as perpendicular to the piston rods. A swivel element is joined to the drive unit, and rocker arms are located on both sides. Each of the rocker arms is connected with one of the piston pumps of a pair, and the ends of the piston rods are located and guided in grooves of the rocker arms. Each pair of the piston pumps is regulated by an adjustment spindle which is common to one pair of piston pumps. The adjustment spindle has two parts with opposite threads. They are connected by a lockable coupling. One spindle part is each associated with one piston pump of one pair.
