Abstract

1836. Oddie, P. F. Jan. 26. Pump valves. - An appliance for regulating hydraulically-operated valves specially adapted for the suction valves of pumps is shown in Figs. 1 and 2 as applied to a plunger pump. To assist the suction valve k to open and to regulate the extent of its opening, an auxiliary pump h driven from the main shaft a forces oil or other fluid through a pipe i into a cylinder m which contains a piston l attached to the suction valve. The suction valve is normally pressed on to its seat by a spring n and is raised by the pressure on its piston just as the pump plunger s is making its section stroke. An adjustably loaded relief valve q placed in a suitable position such as in the pipe i regulates the stroke of the suction valve by relieving the pressure under the valve piston. The maximum stroke of the suction valve is governed by outlet ports t.
