    摘要： A VENTING UNIT CAPABLE OF QUICKLY RELIEVING HEAT AND SMOKE DUE TO FIRES AND PRESSURES DUE TO EXPLOSIONS ORIGINATING IN THE INTERIOR OF A BUILDING. THE VENTING UNIT HAS AT LEAST ONE COVER MEMBER RELEASEABLY RETAINED IN A NORMALLY CLOSED POSITION. FLUID ACTUATED MOTOR MEANS INCLUDING A VARIABLE VOLUME CHAMBER FORCIBLY URGES THE COVER MEMBER TOWARD AN OPEN POSITION. THE COVER MEMBER IS NORMALLY DISCONNECTED FROM THE MOTOR MEANS AND IS FREELY PIVOTAL TOWARD ITS OPEN POSITION ON BEING RELEASED. MOTOR ENERGIZING MEANS, IN THE FORM OF A REPLACEABLE CARTRIDGE CONTAINING PRESSURIZED WORKING FLUIDS, ENERGIZES THE MOTOR MEANS IN RESPONSE TO A SELECTED ELEVATED TEMPERATURE WITHIN THE BUILDING.
