Abstract
1512154 Fluid-pressure actuators H TERAMACHI 23 June 1976 [24 June 1975 16 Oct 1975] 26190/76 Heading F1D A fluid-pressure actuator, Fig. 1 has a piston 8 which is axially fixed to a piston-rod 2 but permits rotation thereof, pistons 6, 7 having threads 5b, 5c which co-operate with threads 5a on the pistonrod, and the cylinder 1 is non-circular so that movement of the pistons 6, 7 relative to the rod 2 causes rotation of the rod. Ports 16, 17, 18 enable the rod 2 to be moved axially and then rotated from the position shown in Fig. 1. Return movement may be first axial and then rotational or vice versa. Fig. 6 (not shown), illustrates an embodiment in which pistons 6, 7 are mirror images of each other and the space t between them is occupied by resilient means.
