Abstract

1282381 Hydraulic motor control circuits CAM GEARS Ltd 5 Jan 1971 [14 Jan 1970] 1806/70 Heading F1P Opposite ends 2, 3 of a double-acting hydraulic actuator 1 connected by lines 5, 6 through a conventional distributing valve 8 to a pump 7 are also connected by lines (6a, 7a to end chambers 9, 10 of a shuttle spool valve 12 the spool 11 of which has internal passages 13, 14 by which the exhaust end of the actuator is connected through one or other of ports 15, 16 to a vented reservoir 17 located above the actuator whereby gas bubbles may escape from the system and make-up hydraulic fluid may be added.
