Abstract
The regeneration cycle has a flow meter in the input pipe fed by a normally open valve. the flow meter is shunted by a pipe with a normally closed valve. The operation is controlled by a timer which is activated when as given quantity of water has flowed through the apparatus. At the start of the cycle the normally open valve is closed and the normally closed valve is opened. At the end of the cycle the timer return the valves to their initial positions. The timer controls the operation by means of cams actuating microswitches.
