Abstract

The automatic dosing unit for inserting fluid additives and agents into the water in a domestic automatic clothes washing machine has a dosing cylinder and spring-adjusted piston. As the spring presses against the piston, the fluid additive is drawn out of its supply vessel. When required, the piston is pressed hydraulically against the spring and the fluid is injected into the machine's system. The system can be used for detergents, rinsing agents, bleaches, fabric softeners and the like. The system ensures that all the functions of the washing machine are automatic, and allows the use of thick and sticky agents without special valve assembles.
