Fluid regulating apparatus

Claim 1

A FLUID PRESSURE TRANSMITTER, COMPRISING A SERIES OF CHAMBERS INCLUDING A FIRST CHAMBER OPEN TO ATMOSPHERIC PRESSURE AND HAVING A FLEXIBLE WALL THEREOF CONSTRUCTED TO PRODUCE MOVEMENT IN RESPONSE TO THE APPLICATION OF PRESSURE THERETO, A SECOND FLEXIBLE WALL FORMING AN OPPOSITE END SURFACE OF THE FIRST CHAMBER, A SECOND CHAMBER ADJACENT THE FIRST CHAMBER HAVING OPPOSITE WALL PORTIONS FORMED BY THE SECOND FLEXIBLE WALL AND A THIRD FLEXIBLE WALL, SEPARATE PASSAGEWAYS ADAPTED TO TRANSMIT AN OUTPUT FLUID PRESSURE SIGNAL GENERATED BY THE TRANSMITTER INTO AND OUT OF THE SECOND CHAMBER, A THIRD CHAMBER FORMED BY THE THIRD FLEXIBLE WALL IN AN OPPOSITE FOURTH FLEXIBLE WALL, SAID THIRD CHAMBER BEING CONNECTED BY A PASSAGEWAY TO ATMOSPHERIC PRESSURE, A MECHANICAL OPERATING CONNECTION POSITIONED TO EXTEND THROUGH A CENTRAL WALL PORTION OF THE SECOND, THIRD AND FOURTH FLEXIBLE WALLS INTO THE FIRST CHAMBER AT ONE END AND POSITIONED TO EXTEND OUT OF THE THIRD CHAMBER AT ITS OTHER END, A PLATE POSITIONED THE FIRST CHAMBER AND OPERABLY CONNECTED TO TRANSMIT MOVEMENT OF THE FIRST FLEXIBLE WALL TO SAID MECHANICAL CONNECTION, A STATIONARY OUTER RING-SHAPED PLATE POSITIONED WITHIN THE SECOND CHAMBER, AN ASSOCIATED RING SHAPED PLATE POSITIONED IN SPACED RELATION WITHIN THE SECOND-MENTIONED PLATE AND BEING OPERABLY CONNECTED FOR MOVEMENT WITH THE MECHANICAL CONNECTION, A BIASING MEANS POSITIONED IN THE THIRD CHAMBER TO APPPLY A PRESELECTED FORCE TO THE MECHANICAL CONNECTION IN A DIRECTION THAT WILL OPPOSE A PRESELECTED MAGNITUDE OF THE FORCE BEING APPLIED TO THE MECHANICAL CONNECTION BY WAY OF THE FIRST FLEXIBLE WALL, A BLEED VALVE POSITIONED ADJACENT SAID OTHER END OF THE MECHANICAL CONNECTION TO GENERATE THE OUTPUT FLUID PRESSURE SIGNAL AND A SPRING-BIASED MECHANICAL LINK OPERABLY CONNECTED AT ONE END FOR MOVEMENT WITH THE MECHANICAL OPERATING CONNECTION AND AT ITS OTHER END TO THE VALVE TO REGULATE THE MAGNITUDE OF THE OUTPUT FLUID PRESSURE BEING TRANSMITTED BY WAY OF THE AFOREMENTIONED PASSAGEWAY TO AND FROM THE SECOND CHAMBER.
