Abstract

1404123 Fluid-pressure actuators K KITAZAWA 7 March 1974 10333/74 Heading F1D A valve actuator, Fig. 10, comprises a pair of cylinders 6, 6' which are reciprocated on a pair of piston-rods 7, 7' by fluid under pressure to rotate a shaft 2 by means of an arm 3. The latter has slots 4 which are engaged by projections 11, 11' on plates 10, Fig. 1, attached to the cylinders. The cylinders are guided by a rod 9 and fluid is supplied through inlets 12, 12', Fig. 10, and pipes 19, 19'. Inlets 12, Fig. 6, connect with bores 16, 16a in the piston-rods and with pipes 19 through bores 13.
