摘要:
The device comprises a duct to receive combustible gas, escaping under pressure from a container, which comprises a duct to receive said gas, a venturi in said duct, a reservoir for a combustion-suppressing fluid connected to the said duct both upstream of and at the said venturi, in relation to the gas flow, in such a way that the pressure differential produced by the passage of the gas through the venturi forces fluid out of the said reservoir into the path of the said gas in the said duct.
