The assembly () links a static housing () of the turbomachine, into which supply lines, in particular fluid supply lines (), arrive, to the blades of the propeller, and comprises: &#x2014;a system for controlling fluid pitch (), rigidly connected to the static housing (), capable of being linked to the supply lines, &#x2014;a linear actuator () having two chambers separated by a piston () of which the sliding is dictated by the control system and allows the blades to rotate, and &#x2014;two concentric tubes () housed in the planetary shaft of the epicyclic reduction gear and linking the system () to the actuator () by delimiting two fluid passages () linked, respectively, with the two chambers () of the actuator.
