Claim 1
Independent Claim
188 words
A NORMALLY-CLOSED VALVE, COMPRISING A VALVE BODY HAVING AN ELONGATED VALVE CHAMBER THEREIN WITH A CYLINDRICAL WALL SURFACE, AN ELONGATED RAM ELEMENT MOUNTED IN SAID CHAMBER FOR MOVEMENT LONGITUDINALLY THEREOF, SAID RAM ELEMENT HAVING A GENERALLY CYLINDRICAL SHAPE CORRESPONDING GENERALLY TO SAID CYLINDRICAL WALL SURFACE, A PORTION OF SAID RAM HAVING A FLAT SURFACE ON ONE SIDE THEREOF AND PARALLEL TO THE AXIS OF SAID RAM, SAID PORTION OF SAID RAM HAVING A RECESS THEREIN AND ALSO HAVING A PORT EXTENDING THERETHROUGH, A BLIND NIPPLE ELEMENT HAVING A BLIND INNER END INSERTED A SUBSTANTIAL DISTANCE INTO SAID RECESS IN SAID PORTION OF SAID RAM, THE WALL OF SAID RECESS FULLY ENCOMPASSING SAID BLIND INNER END, WALL MEANS PROVIDED IN SAID VALVE BODY TO DEFINE AN OUTLET FLUID PASSAGE OPPOSITE SAID BLIND INNER END OF SAID NIPPLE, AND MEANS TO EFFECT SUDDEN AND FORCEFUL SHIFTING OF SAID RAM LONGITUDINALLY OF SAID VALVE CHAMBER TO SHEAR OFF SAID BLIND INNER END OF SAID NIPPLE AND CAUSE SAID PORT TO BE DISPOSED BETWEEN THE REMAINING PORTION OF SAID NIPPLE AND SAID OUTLET FLUID PASSAGE TO THEREBY CREATE A FLOW PASSAGE THEREBETWEEN.
Claim 2
Dependent Claim
214 words
A NORMALLY CLOSED VALVE COMPRISING IN COMBINATION A VALVE BODY HAVING A FLUID FLOW PASSAGE THERETHROUGH AND AN ACTUATING CHAMBER THEREIN TRANSVERSELY INTERSECTING SAID PASSAGE, A FLUID LINE FITTING HAVING AN INTEGRAL DISC SEALING THE END THEREOF, SAID FITTING BEING THREADED INTO SAID PASSAGE WITH SAID DISC PROJECTING INTO SAID CHAMBER TRANSVERSE TO THE LONGITUDINAL AXIS OF SAID CHAMBER TO BLOCK THE FLOW OF FLUID THROUGH SAID PASSAGE, A SHEARING MEMBER SLIDABLY MOVABLE IN SAID CHAMBER AND HAVING A CYLINDRICAL CAVITY INTO WHICH SAID DISC EXTENDS, DRIVING MEANS FOR DRIVING SAID SHEARING MEMBER LONGITUDINALLY IN SAID CHAMBER TO SHEAR OFF SAID DISC FROM SAID FITTING, SAID DRIVING MEANS COMPRISING A SQUIB POSITIONED IN SAID CHAMBER, MEANS FOR FIRING SAID SQUIB, AND AN ACTUATING PISTON INDEPENDENTLY SLIDABLY MOVABLE IN SAID CHAMBER AND RESPONSIVE TO THE EXPLOSIVE GASES GENERATED WHEN SAID SQUIB IS FIRED FOR DRIVING SAID SHEARING MEMBER LONGITUDINALLY IN SAID CHAMBER TO SHEAR OFF SAID DISC FROM SAID FITTING, MEANS IN SAID SHEARING MEMBER FOR COMMUNICATING FLUID THROUGH SAID PASSAGE WHEN SAID DISC IS SHEARED OFF FROM SAID FITTING, AND MEANS IN SAID SHEARING MEMBER FOR DIRECTING A PORTION OF SAID FLUID IN SAID PASSAGE AGAINST SAID ACTUATING PISTON FOR BALANCING THE FORCES APPLIED TO SAID SHEARING MEMBER BY SAID FLUID IN SAID PASSAGE.
