Abstract

1369244 Hydraulic reciprocating motors FUJITSU Ltd 7 Dec 1971 [26 Dec 1970] 56680/71 Heading F1A [Also in Division G3] A stepping motor 1 drivingly engages a spool 2a, rotation of the spool causing its axial movement by a screw and nut arrangement 5, movement of the spool causing rotation of the hydraulic motor 3, with the shaft 3d providing feedback for the spool. An oil supply line 6 introduces hydraulic fluid into the motor 3 and it exhausts from line 7. The line 7 also communicates with a chamber 3a, a tube 10 being provided so that oil only drains away from the chamber at a high level when the motor is used in a vertical position.
