Abstract
A peristaltic detergent feed pump and peristaltic rinse feed pump are employed to supply their respective ingredients to a washing machine, chemical reactor, or the like. The detergent feed is supplied by a peristaltic pump, and the amount of feed is detected by a sensor such as a conductance probe controlled by a special circuitry means. The peristaltic rinse feed pump is driven by a shaded pole motor, comprising a constant torque, A.C. drive and a D.C. electromagnetic, shaded pole brake portion. The net effect of employing a circuit controlled conductance sensor and D.C. brake enables the detergent and rinse ingredients to be fed linearly to the dishwasher.
