Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
182 words
APPARATUS FOR RELEASING STORED ENERGY COMPRISING HOUSING MEANS, A WALL HAVING AN ORIFICE IN SAID HOUSING MEANS, A PISTON POSITIONED WITHIN SAID HOUSING MEANS AND HAVING A SURFACE CONFRONTING SAID WALL, MEANS FOR EXERTING A FIRST FLUID PRESSURE ON SAID PISTON URGING SAID PISTON TOWARD SAID WALL TO COVER SAID ORIFICE, MEANS FOR EFFECTING A PRESSURE SEAL BETWEEN SAID PISTON AND SAID WALL, MEANS FOR APPLYING A SECOND FLUID PRESSURE ON AN AREA OF SAID SURFACE COVERING SAID ORIFICE TO BALANCE SAID FIRST FLUID PRESSURE, MEANS FOR EXERTING A THIRD FLUID PRESSURE ON AN AREA OF SAID SURFACE OUTSIDE SAID PRESSURE SEAL FOR CO-ACTING WITH SAID SECOND FLUID PRESSURE TO DISENGAGE SAID PRESSURE SEAL AND EXPOSE AN INCREASED AREA OF SAID PISTON TO SAID SECOND FLUID PRESSURE TO MOVE SAID PISTON, AND PRESSURE RELEASE MEANS ATTACHED TO SAID PISTON FOR RELEASING SAID SECOND FLUID PRESSURE TO AN OPENING IN SAID HOUSING MEANS AFTER MOVEMENT OF SAID PISTON IS BEGUN, SAID PRESSURE RELEASE MEANS BEING POSITIONED TO COVER SAID OPENING WHEN SAID PISTON IS URGED TOWARD SAID WALL TO EFFECT SAID PRESSURE SEAL.
