Lubrication oil transfer device for use in pitch orientation system of blades of propeller of e.g. open rotor type turbomachine, of aircraft, has injection rods engaging with annular moving part for conveying lubricant into actuator

摘要

The device (50) has a fixed cylindrical shell (25) secured to a cylindrical fixed part of an actuator, and a lubricant supply provided on a front side of the shell. An axial through-hole is formed in a wall of the shell and connected to the lubricant supply on the front side of the shell. A lubricant collection and distribution ring (55) is connected coaxially on a rear side of the shell for placing an internal lubricant reception cavity (56) in connection with the hole. Injection rods (42) engage with an annular moving part to convey the lubricant into the actuator. An independent claim is also included for a pitch orientation system of blades of a propeller of turbomachine.
