Abstract

963,411. Ventilators. SULZER FRERES S.A. July 6, 1962 [July 7, 1961], No. 26084/62. Heading F4V. [Also in Division F2] A valve for protecting a ventilation shaft 4 of an air-raid shelter in the event of an explosion comprises a valve plate 9, preferably of sheet metal covered with a plastics material, which is suspended by springs 10 so as to be free from friction. Valve seats 12, 13 in the form of gratings are provided against which the valve plate seats in response to a pressure wave and subsequent suction produced by an explosion. In a modification, two valves are provided, one at each end of the shaft 4, and the valve plates co-operate with one seat only, one valve being closed by the pressure wave and the other by the subsequent suction.
