Abstract

3693. Ogden, J. E. L. Feb. 14. Reducing - valves. -Relates to steam and like reducing- valves, particularly of the kind described in Specification No. 1747, A.D. 1893. T h e main equilibrium valve B is actuated by a piston D on the stem c'of the auxiliary valve C, which has projections c<2> to engage the valve B. Highpressure steam passes from the inlet through the hollow stem c', and thence, leaking between a loose sliding plug E and a nut F, to the top of the piston, the underside of which communicates with the valve outlet, as shown. The pressures above the piston and in the outlet are regulated by a spring-pressed relief valve H. To prevent chattering and too sudden motion of the valve C, an adjustable spring is provided within or without the casing. In a modification, a dash-pot or cataract is employed. Instead of a piston D, a diaphragm may be used. An independent supply passage may be used to convey steam to the upper side of the piston.
