Abstract

1349221 Hydraulic actuators DAIEI KOGYOSHA K K 12 Sept 1972 [14 Sept 1971 3 April 1972] 42394/72 Heading F1D A fluid operated rotary actuator comprises an internally threaded piston 13, Fig. 1, which rotates a co-operating threaded rod 17-18 as it moves linearly along the cylinder guided by keyways 20 engaged by keys pressed in the circumference of the cylinder 10. The keyways may be parallel to the axis of the piston or diagonal, Fig. 5, (not shown). Figs. 4A-4D, (not shown) illustrate various possible crosssections of key and keyway. Fig. 7 shows an embodiment in which both linear and rotational movement of the shaft 17 are effected, the latter by a rotary actuator 35 and the former by a piston 31. The piston 31 has chambers 33, 34 respectively supplied with fluid through ports 44, 40. Port 40 is attached to the piston 31 and slides in a slot 38 in the wall of cylinder 28.
