<p>Thorough mixing of the chemicals into the washing water is ensured by a gear pump driven by a water turbine in the feed line between the water supply point and the liquor container; the pump drawing from a storage vessel and feeding into the water delivery line. In the suction line of the pump there is an adjustable choke valve and an electrically operated valve. The inlet to the liquor container is widened to receive powdered washing materials. The delivery of liquid washing materials opt. together with fabric conditioners, disinfectants, etc. into the liquor container of an automatic washing machine is effected without electric power and without additional and expensive electrical contacts in the programming circuit.</p> |
