Abstract

The machine is operated by pressing the button which sets up the electric circuit so that the pump begins to convey water into the upper zone of the chamber containing the piston so that owing to pressure the piston is forced down and the amount of water in the lower zone is forced into the outlet pipe and from there to the heat exchanger. When the shaft of the piston rod contacts one of the bars of the dosing control device the movable part inside the distributor is displaced so that the connections between the different pipes are changed and pump supplies water to the lower zone of the chamber to cause the piston to rise. The water collected in the upper zone is passed through a pipe and the distributor into the outlet pipe and from there to the heat exchanger. As soon as the piston has moved right to the top, the piston rod breaks the circuit for the machine and starts the supply to the pump.
