Abstract
Abstract VALVE CLOSURE IS PIVOTALLY CONNECTED TO ONE END OF A LINK FORMING ONE BAR OF A TOGGLE. OTHER BAR OF TOGGLE COMPRISES A LEVER FORMED BY A SPRING FORK. ONE TINE OF FORK IS PIVOTALLY CONNECTED OTHER END OF LINK PROVIDING THE KNEE OF THE TOGGLE. ANOTHER TINE OF FORK IS PIVOTALLY CONNECTED TO VALVE BODY AT A POINT FORMING THE FULCRUM OF THE LEVER. THE STEM OF THE FORK IS CONNECTED TO VALVE ACTUATION MEANS WHICH MAY BE A FLOAT. A SETSCREW THROUGH ONE END OF ONE TINE BEARS AGAINST END OF OTHER TINE WHEREBY TINE SPACING CAN BE ADJUSTED SO THAT LENGTH OF TOGGLE BARS JUST EXCEEDS DISTANCE FROM FULCRUM TO VALVE CLOSURE WHEN VALVE IS IN CLOSED POSITION, GIVING MAXIMUM CLOSING THRUST.
