Abstract

183,840. Aktiebolaget Vaporackumulator. July 29,1921, [Convention date]. Fluid-actuated valves.-Apparatus for operating a valve d so as to maintain a constant pressure in a conduit e comprises a servo-motor c, the supply to and exhaust of liquid from the servomotor cylinder being governed by a valve s carried by a piston b. Liquid supplied through a pipe o and regulating-valve m acts on the piston b, and the position of the latter is determined by the amount of liquid allowed to escape. through a pipe h having apertures v controlled by a member 3 in accordance with the pressure in the conduit e. The apertures v are disposed in opposite sides of the pipe h, and the forked member 3 is carried by a lever 2 acted on by a spring 4 and pins carried by diaphragms g.
