The device (18) is intended to supply a rotating linear displacement actuator capable of controlling the pitch of the blades of a propeller, according to separate operating states, from a rotary power assembly, the device being arranged so as to be located between the power assembly and the actuator, along a longitudinal axis (A), and being connected in rotation therewith. According to the invention, the device comprises means (20) for supplying fluid interacting with said power assembly and defining as many supplies as there are operating states of the actuator, and a fluid distributor (21) to which said supplies are connected and having separate channels for transporting the fluid in the direction of the actuator according to the operating states, by means of tubular equipment (25) connected to the distributor. |

1. Device for supplying and distributing fluid for a rotating linear displacement actuator capable of controlling the pitch of the blades of a propeller, according to separate operating states, by means of a rotary power assembly, said device being arranged so as to be located between the power assembly and the actuator, along a longitudinal axis, and being connected in rotation therewith, characterised in that it comprises:
means for supplying fluid comprising radial arms having internal passages capable of interacting with said power assembly and defining as many supplies as there are operating states of the actuator, a fluid distributor to which the internal passages of the arms of said supplies are connected, and having channels capable of separately transporting the fluid in the direction of the actuator according to the operating states, and tubular equipment connected coaxially to the distributor and forming at least two independent chambers connected to separate lateral channels of the distributor, and one or the other of which are capable of being in communication with said actuator for two operating states thereof, said distributor comprising another central channel, along the common axis, capable of being in direct communication with a supply tube of the actuator for another operating state thereof.
