1. A CIRCUIT INTERRUPTER OF THE FLUID-BLAST TYPE INCLUDING A TANK CONTAINING A DIELECTRIC FLUID, A BAFFLE PLATE HAVING A PAIR OF EXHAUST OPENINGS DISPOSED INTERIORLY WITHIN THE TANK AND DIVIDING THE TANK INTO A PRESSURE-GENERATING CHAMBER AND AN EXHAUST CHAMBER, A PAIR OF RELATIVELY STATIONARY CONTACTS SUPPORTED BY THE BAFFLE PLATE ADJACENT SAID PAIR OF EXHAUST OPENINGS WITHIN THE PRESSURE-GENERATING CHAMBER, A RELATIVELY STATIONARY BRIDGING CONTACT DISPOSED WITHIN THE PRESSURE-GENERATING CHAMBER, SAID BRIDGING CONTACT FORMING A SPACED PAIR OF RELATIVELY STATIONARY PRESSURE-GENERATING CONTACTS, A PAIR OF COOPERABLE MOVABLE CONTACT STRUCTURES, EACH MOVABLE CONTACT STRUCTURE COOPERATING WITH ONE OF SAID RELATIVELY STATIONARY CONTACT AND WITH ONE OF SAID RELATIVELY STATIONARY PRESSURE-GENERATING CONTACTS TO DRAW A PRESSUREGENERATING ARC AND A SERIALLY RELATED INTERRUPTING ARC BEING DRAWN TRANSVERSELY ACROSS AN EXHAUST OPENING, AND THE PRESSURE GENERATED WITHIN THE PRESSURE-GENERATING CHAMBER BY THE TWO PRESSURE-GENERATING ARCS FORCING FLUID TRANSVERSELY ACROSS THE INTERRUPTING ARCS AND THROUGH THE PAIR OF EXHAUST OPENINGS TO THEREBY EFFECT CIRCUIT INTERRUPTION.
