Automatic controlling apparatus of operation fluid pressure

Claim 1

AN AUTOMATIC PRESSURE CONTROLLING APPARATUS COMPRISING A ROTATIVE MEMBER COUPLED TO A ROTATIONALLY OPERATED MECHANISM FOR ROTATION THEREWITH, OPERATING FLUID PASSAGE MEANS EXTENDING THROUGH SAID MEMBER FOR RECEIVING A FLUID WHERE PRESSURE IS TO BE CONTROLLED IN ACCORDANCE WITH THE ROTATIONAL INPUT TO SAID ROTATIVE MEMBER, AND A PLURALITY OF CENTRIFUGALLY OPERATED VALVES CARRIED BY SAID ROTATIVE MEMBER, EACH OF SAID VALVES HAVING AN OUTSIDE FLUID PASSAGE IN COMMUNICATION WITH THE OPERATING FLUID IN SAID OPERATING FLUID PASSAGE MEANS, AND AN INSIDE FLUID PASSAGE IN COMMUNICATION WITH A PRESSURE DISCHARGE PASSAGE MEANS FOR SAID OPERATING FLUID, INDIVIDUAL SPRING MEANS FOR URGING SAID VALVES TO A CLOSED CONDITION IN CONJUNCTION WITH THE CENTRIFUGALLY DEVELOPED FORCES OF SAID ROTATIVE MEMBER, SAID VALVES WHEN IN SAID CLOSED CONDITION SEALING SAID OPERATING FLUID PASSAGE MEANS FROM SAID DISCHARGE PASSAGE MEANS, AND WHEN OPENED PROGRESSIVELY ESTABLISHING A COMMUNICATION PASSAGE BETWEEN SAID OPERATING FLUID PASSAGE MEANS AND SAID DISCHARGE PASSAGE MEANS, THE PRESSURE CONTROL CHARACTERISTICS OF SAID VALVES OPERATIVELY RELATED, SUCH THAT INDIVIDUAL ONES OF SAID VALVES SEQUENTIALLY CONTROL THE PRESSURE OF THE OPERATING FLUID BETWEEN PREDETERMINED REVOLUTIONARY SPEEDS.
