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.
Claims5
A multifunction pneumatic system for controlling operating components of washing machines, comprising:
- at least one pneumatic electric pump;
- at least one pneumatic valve associated with the operating components of the washing machines;
- at least one pneumatic conduit connecting said at least one pneumatic electric pump to said at least one pneumatic valve;
- elastic calibrated means for biasing the action of said at least one pneumatic valve, the operating components reacting against the elastic calibrated means;
- water distributor means selectively controllable to activate individually various ones of the components;
- and
- at least one bellows element connected to said at least one pneumatic valve by at least one compressed air conduit and operatively connected to said water distributor means for causing said water distributor means to selectively activate individual ones of the components which thereby empty into a tub of the washing machine.
