Abstract

1352900 Fluid-pressure servomotor systems FUJITSU Ltd 7 Dec 1971 [26 Dec 1970] 56681/71 Heading G3P An electro-hydraulic pulse motor has the output shaft of an electric pulse motor 21 connected to the spool of a four-way pilot valve 22 by reduction gearing 15, 16. The back lash in the gearing is adjusted by a rotatable ring 20 having two circular internal surfaces which are respectively fitted to the electric motor and valve and are eccentric to one another. The pilot valve is coupled to an axial-piston rotary hydraulic motor by a screw-nut coupling providing feedback.
