Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
174 words
A VALVE MECHANISM COMPRISING A VALVE BODY, AT LEAST ONE OUTLET PORT IN SAID VALVE BODY, A FIRST AND A SECOND PORT IN SAID VALVE BODY ADAPTED TO BE CONNECTED TO A FLUID UNDER PRESSURE, VALVE MEANS IN SAID VALVE BODY MOVABLE BETWEEN A FIRST AND A SECOND POSITION TO CONTROL THE FLOW OF A FLUID THROUGH SAID VALVE MECHANISM, SAID VALVE MEANS PROVIDING A PASSAGE BETWEEN SAID FIRST PORT AND SAID OUTLET PORT AND PREVENTING THE FLOW OF FLUID BETWEEN SAID SECOND PORT AND SAID OUTLET PORT WHEN IN THE FIRST POSITION, AND PROVIDING A PASSAGE BETWEEN SAID SECOND PORT AND SAID OUTLET PORT AND PREVENTING THE FLOW OF FLUID BETWEEN SAID FIRST PORT AND SAID OUTLET PORT WHEN IN THE SECOND POSITION, BIASING MEANS IN SAID VALVE BODY FOR BIASING SAID VALVE MEANS TO SAID FIRST POSITION, VALVE OPERATING MEANS FOR MOVING SAID VALVE TO THE SECOND POSITION, AND MEANS SELECTIVELY ACTUATABLE TO COMMUNICATE FLUID UNDER PRESSURE FROM SAID FIRST AND SECOND PORTS TO SAID VALVE OPERATING MEANS TO OPERATE THE SAME.

Claim 3
Dependent Claim
211 words
IN A METHOD FOR CONTROLLING THE FLOW OF FLUID UNDER PRESSURE, THE STEPS COMPRISING CONNECTING A PORT WITH THE FLUID UNDER PRESSURE, PROVIDING FOR A COMMUNICATION OF THE FLUID UNDER PRESSURE FROM THE PORT TO THE OUTLET, ALTERNATELY CLOSING AND OPENING THE COMMUNICATION OF THE FLUID UNDER PRESSURE FROM THE PORT TO THE OUTLET, UTILIZING THE FLUID UNDER PRESSURE AT THE PORT TO ALTERNATELY OPEN AND CLOSE THE COMMUNICATION OF FLUID FROM THE PORT TO THE OUTLET, COMMUNICATING THE FLUID UNDER PRESSURE FORM THE OUTLET TO EXHAUST THE FLUID THEREFROM TO ANOTHER PORT AFTER THE COMMUNICATION FROM THE FIRST MENTIONED PORT TO THE OUTLET IS CLOSED AND CLOSING THE COMMUNICATION FROM THE OUTLET TO THE OTHER PORT BEFORE OPENING THE COMMUNICATION FROM THE FIRST MENTIONED PORT TO THE OUTLET, DISCONNECTING THE FIRST MENTIONED PORT FROM THE FLUID UNDER PRESSURE AND CONNECTING THE OTHER PORT WITH THE FLUID UNDER PRESSURE, AND UTILIZING THE FLUID UNDER PRESSURE AT THE OTHER PORT TO ALTERNATELY OPEN AND CLOSE THE COMMUNICATION FROM THE OTHER PORT TO THE OUTLET, AND REVERSELY OPENING ANUD CLOSING RESPECTIVELY A COMMUNICATION OF THE FLUID UNDER PRESSURE FROM THE OUTLET TO EXHAUST THE SAME TO THE FIRST MENTIONED PORT AFTER THE COMMUNICATION FROM THE OTHER PORT TO THE OUTLET HAS COMPLETELY CLOSED.
