Reaction-transmitting mechanism adapted for pressure differential motor use

Claim 1

IN REACTION-TRANSMITTING MECHANISM ADAPTED FOR USE IN COOPERATION WITH A WORK-PERFORMING ELEMENT TO TRANSMIT REACTION THEREFROM TO A POWER MEMBER OPERATIVE TO EXERT THE MAJOR PORTION OF PRESSURE ON SAID ELEMENT, AND TO A PERSONALLY-ACTUATABLE MEMBER EFFECTIVE TO CONTROL OPERATION OF SAID POWER MEMBER AND SIMULTANEOUSLY CONTRIBUTE THE BALANCE OF PRESSURE ON SAID ELEMENT, THE IMPROVEMENT WHICH COMPRISES: A MOVABLE MEMBER; A PRESSURE AREA ON THE POWER MEMBER; ANOTHER PRESSURE AREA ON SAID MOVABLE MEMBER RADIALLY SPACED FROM THE FIRSTNAMED PRESSURE AREA; A FULCRUM AREA PROVIDED ON SAID WORK ELEMENT INTERMEDIATE SAID TWO PRESSURE AREAS IN OFFSET RELATIONSHIP THERETO; A PAIR OF INTERFITTING PORTION CARRIED BY SAID WORK ELEMENT AND SAID POWER MEMBER RESPECTIVELY TO PROVIDE LIMITED RELATIVE MOVEMENT THEREBETWEEN FROM A NORMALLY, ABUTTING RELATIONSHIP; MEANS HAVING RADIALLY SPACED SURFACE PORTIONS ON ONE SIDE CONTIGUOUS TO SAID TWO PRESSURE AREAS RESPECTIVELY, AND AN INTERMEDIATE SURFACE PORTION ON THE OPPOSITE SIDE ENGAGEABLE BY SAID FULCRUM AREA WHEN SAID INTERFITTING PORTIONS ARE IN ABUTTING RELATIONSHIP WHEREIN SAID MEANS IS INEFFECTIVE TO TRANSMIT REACTION; AN OPERATIVE CONNECTION BETWEEN SAID PERSONAL AND MOVABLE MEMBERS TO PROVIDE UNITARY MOVEMENT THEREOF RELATIVE TO SAID POWER MEMBER
