Electromechanical fluidic transducer
Abstract
Abstract AN ELECTROMECHANICAL FLUIDIC TRANSDUCER HAS A FLOW FEED LINE COMMUNICATING WITH TWO FLOW OUPUTS. TWO CONTROL SIGNAL RESPONSIVE ELECTROMAGNETIC DEVICES ARE OPERABLE TO SELECT THE FLOW OUPUT, EACH CONTROLLING FLOW RELATIVE TO A RESPECTIE OUTPUT. A SIGNAL FLOW SWITCHING ELEMENT IS MOVABLE, UNDER THE INFLUENCE OF FLUID FLOW, INTO FLOW BLOCKING RELATION IN A SELECTED ONE OF THE FLOW OUTPUTS, AND THE SWITCHING ELEMENT IS LOCKABLE IN ITS BLOCKING POSITION BY THE ASSOCIATED ELECTROMAGNETIC DEVICE. THE FLOW SWITCHING ELEMENT IS A FORKED ELEMENT, AND EITHER MAY BE PIVOTED AT THE FORK BETWEEN THE TWO OUTPUTS OR MAY BE FLEXIBLE, IN THE FORM OF A LEAF SPRING. ADJUSTMENT CANALS OR DUCTS COMMUNICATE WITH THE FLOW FEED OR SUPPLY LINE FROM OPPOSITE SIDES TO COMPENSATE FOR ASYMMETRY OF THE FLOW CONTROL ELEMENT.
