Abstract

203,765. English Electric Co., Ltd., and Rothera, L. June 10, 1922. Actuating - mechanism.- For operating an electric controller a fluid pressure motor is controlled by a valve and a mechanical relay device of the floating lever type which closes the valve when the required movements have been made. In the apparatus shown in the drawing an operator's handle 1 acts through diaphragms 3, 8 and a liquid-filled pipe 6 upon one end of a lever 10 adapted to open valves 16, 17 so as to admit oil under pressure to a rotary hydraulic motor 14, which is geared to the opposite end of the lever 10. The valves are thus closed when the motor. has travelled a distance proportional to the original movement of the handle.
