Abstract

989,477. Gas turbine plant. ROLLS-ROYCE Ltd. Jan. 30, 1964, No. 4079/64. Heading F1G. [Also in Division F2] A lubricator for a bearing comprises a rotor 35 having a passage 70,71 with an inlet from a stationary reservoir 55 and an outlet which at one angular position of the rotor communicates with a passage 76 leading by ducts 81, 83 to bearings 21, 23 within which the lubricator lies. As described, the lubricator is mounted inside the shafts 16, 17 of a twin-shaft vertically mounted jet lift engine, the rotor being driven by the L.P. shaft 17 through a member 50. The reservoir contains a piston 37 pressed against the rotor by a spring 42 and having an opening 74 by which the inlet of the passage 71 communicates with the reservoir at one angular position of the rotor. The reservoir is filled through a tube 60, has an overflow provided by passages 66, 67 in the rotor shaft 34, and is mounted on a torque tube 33 convoluted to allow for thermal expansion. A non-return valve (Fig. 2, not shown) is located in the passage 70 and is opened by centrifugal force when the rotor rotates to allow lubricant to be centrifuged by the rotor on to the bearings. The flow of oil is shown by arrows in the Figure.
