Abstract

1,182,288. Oscillating-vane actuators. LICENTIA PATENT-VERWALTUNGS - G.m.b.H. June 7, 1967 [June 7, 1966], No. 26203/67. Heading F1F. An oscillating-vane hydraulic actuator, particularly for operating a ship's rudder, comprises a hub 20, Fig. 3, having a bore formed with a keyway for connection to the rudder post and flanges 22, 23 between which is formed an annular chamber of semicircular cross-section sub-divided by a plurality of vanes secured to the hub and a plurality of abutments, secured to a cylindrical housing 27 into a number of pressure chambers into which hydraulic pressure fluid may be supplied and withdrawn through annular passages 49, 54 and bores in the housing, not shown. The vanes, 28, 29, 30, are freely mounted in grooves formed in the curved hub surface to eliminate fixing bolts and are each formed with a peripheral groove mounting an endless sealing ring. Similarly, abutments three in number, one 31 shown, are freely mounted in grooves in the housing 27 and again endless sealing rings are mounted in peripheral grooves in the abutments. The abutments are axially located in the housing by means of guide rings 43, 53 fitting in counter-bores in the ends of the housing. Gland rings with packing beneath are secured to the rings 43, 53. Comparing the semicircular, cross-section area pressure chamber with the usual rectangular cross-section chamber, the centre of area of the chamber is farther from the hub axis with consequential increase in torque on the rudder and decrease in bending stresses on the abutments.
