Abstract

136,615. Cockburns, Ltd., Cockburn, D., and Machicoll, D. Dec. 16, 1918. Safety-valves. - safetyvalve of the kind provided with an actuating-piston slidably mounted on the valve spindle has the piston so arranged that it is withdrawn from its cylinder when the valve is closed. In the closed position, the piston 2 rests on the valve member 4, and, as the valve lifts, the piston passes into a cylindrical aperture in a partition 6; the outlet pressure then forces it into contact with the collar 5 to increase the lift of the valve. Specification 112,575 is referred to.
