Abstract

1517503 Rotary positive-displacement fluidmachines BROWN BROS & CO Ltd 22 Oct 1975 [3 Aug 1974] 34294/74 Heading F1F [Also in Division B7] An hydraulic actuator for a hydrofoil or a ship's rudder 1 has a casing 8 accommodating a vaned rotor 3 and movable about the axis of the latter by hydraulic piston-and-cylinder units 11, 12 so that the rotor can be turned through a greater angle e.g. 90 degrees, on either side of its median position, Fig. 3 (not shown).
