Abstract

220,897. Edwards, G. T., and Blakeborough, R. A. March 25, 1924. Addition to 207,004. Pressure-regulating valves.-A pressure-regulating valve having a differential piston 4<1>, 4<2> arranged to work in a cylindrical member 2<1> depending from the cover 2 of an enlarged part of the casing 1<6> is provided with means whereby a variable load can be imposed upon the differential piston. In the form shown the valve is hydraulically loaded by means of liquid introduced through a filling aperture d to a tube a and acted on by a movable cap b loaded by weights c. In a modification the loading device comprises a weighted piston working in a cylinder connected by a pipe to the passage 10.
