Abstract

A conduit-break valve for a double hose or conduit is designed to operate under a higher pressure between the hoses or conduits than that prevailing in the inner hose or conduit and than that of the ambient atmosphere. The valve has a valve member (16) which is urged by a spring (24) towards its valve seat (15). A diaphragm or piston device (18) normally maitains the valve member (16) in open position by the action of the pressure in a pressure chamber (22) which is connected to the space between the hoses. At a break of the inner and/or the outer one of the hoses or conduits the pressure in the pressure chamber (22) is reduced and the valve is closed by the action of the spring (24).
