Pure fluid logic element

Claim 1

A FLUID INVERTER COMPRISING; A BODY MEMBER HAVING A FLUID INTERACTION CHAMBER DISPOSED THEREIN, SAID INTERACTION CHAMBER HAVING AN END WALL IN WHICH A FLUID POWER NOZZLE IS DISPOSED, SAID FLUID POWER NOZZLE BEING ADAPTED WHEN SUBJECTED TO FLUID INPUT PRESSURE TO PROJECT A POWER JET THROUGH THE INTERACTION CHAMBER, AN OUTPUT DUCT POSITIONED TO RECEIVE THE UNDEFLECTED POWER JET, SAID OUTPUT DUCT COMPRISING FIRST AND SECOND SPACED APART WALL MEMBERS LOCATED DOWN STREAM FROM THE POWER NOZZLE AND ON OPPOSITE SIDES OF THE AXIS OF THE POWER NOZZLE, A CONTROL SIGNAL CHAMBER HAVING AN INPUT DUCT AT ONE END THEREOF FOR RECEIVING CONTROL FLUID INPUT SIGNALS AND A MOUTH PORTION AT THE OTHER END THEREOF WHICH OPENS INTO THE INTERACTION CHAMBER ON THE SAME SIDE OF THE POWER NOZZLE AS THE FIRST WALL MEMBER OF THE OUTPUT DUCT, THE SAID MOUTH PORTION EXTENDING FROM THE POWER NOZZLE TO A POINT AT LEAST ONE THIRD THE LENGTH OF THE INTERACTION CHAMBER DOWNSTREAM FROM THE POWER NOZZLE, SAID CONTROL SIGNALIS CHAMBER BEING OPERATIVE SO THAT WHEN A CONTROL FLUID IS APPLIED THERETO A STATIC PRESSURE SIGNAL WILL EXIST AT SAID MOUTH PORTION THEREBY TO DEFLECT THE POWER JET AWAY FROM SAID OUTPUT DUCT, A VENT FOR SAID INTERACTION CHAMBER COMPRISING THE AREA BETWEEN THE SAID END WALL AND THE SECOND OF SAID WALL MEMBERS COMPRISING SAID OUTPUT DUCT, AND A DIVIDER BLOCK LOCATED IN THE SAME VENT DIVIDING SAID VENT INTO TWO UNLOADED VENT CHANNELS THE FIRST VENT CHANNEL OF WHICH IS DEFINED BY A FIRST SURFACE OF SAID DIVIDER BLOCK AND THE SAID END WALL AND THE SECOND VENT CHANNEL OF WHICH IS DEFINED BY A SECOND SURFACE OF SAID DIVIDER BLOCK AND THE SECOND OF SAID WALL MEMBERS OF SAID OUTPUT DUCT; THE SECOND VENT CHANNEL PROVIDING AN EXHAUST PATH FOR THE POWER JET WHEN IT IS DEFLECTED BY A SUITABLE PRESSURE APPLIED TO THE CONTROL CHAMBER, SAID SECOND SURFACE OF SAID DIVIDER BLOCK FORMING AN ACUTE ANGLE WITH THE AXIS OF THE POWER JET AND BEING POSITIONED AND DIMENSIONED TO PROVIDE A BOUNDARY LAYER ATTRACTION FORCE FOR THE POWER JET ONLY WHEN SAID POWER JET IS IN ITS DEFLECTED POSITION, AND SAID FIRST VENT ACTING TO REDUCE THE BOUNDARY LAYER ATTRACTION FORCE OF THE SECOND SURFACE OF SAID DIVIDER BLOCK SO THAT IT IT INSUFFICIENT TO MAINTAIN SAID POWER JET IN ITS DEFLECTED POSITION IN THE ABSENCE OF A SUITABLE CONTROL PRESSURE APPLIED TO SAID CONTROL ORIFICE.
