Abstract

254,822. Blakeborough, R. A., and Broadhead, J. B. April 20, 1925. Pressure-regulating valves. - A pressure regulator of the kind actuated by a differential piston coaxial with the main valve and controlled by an auxiliary valve seating on the main valve has the auxiliary valve actuated by a piston or diaphragm acting through a lever. In the form shown in the Figure the auxiliary valve 19 seats on the underside of the main valve 12 and is connected by a spindle 17 and weighted lever 1 to the actuating piston 6 which is subject to outlet pressure admitted through a pipe 8 controlled bv a valve 9. The main valve is carried by a piston 11 subject to inlet pressure admitted through a conduit 14 throttled by a valve 15. The piston 11 is provided with a sleeve 21 packed by a stuffing box 20 and loaded by dead weights 22 to give the main valve a bias in the closing direction. The auxiliary valve may be arranged to seat on top of the main valve in which case the lever may be arranged to engage the top of the sleeve 21 to assist in the closing of the main valve. A weighted lever or a spring may be used in place of the dead weight 22.
