ABSTRACT:
A multifunction pneumatic system designed to control different components for domestic and/or industrial washing machines. The system includes a pneumatic electric pump connected to a manifold from which solenoid valves, controlled by the machine timer are derived. The solenoid valves act by means of tubular conduits on corresponding diaphragm valves acting on different mechanisms such as the closing hook of the loading door, the electric switches, the pressure switch controlling the level of water in the machine tub and similar function.
