A hydraulic assembly for an aircraft engine includes a pump with a housing and a rotor arranged inside the housing. The housing has at least one hydraulic line configured for the passage of a fluid; and a hydraulic transfer unit comprising: a hydraulic transfer block attached to the housing and comprising an internal fluid passage channel which communicates with the hydraulic line, and a casing which covers the transfer block and which is guided in rotation about an axis of revolution (Y) and about the transfer block, the casing having a fluid outlet port that communicates with the internal channel.

Hydraulic assembly for an aircraft engine

A telescopic actuator comprising a cylinder () in which a rod () is mounted to slide along a sliding axis (X), the actuator including a locking member comprising a locking finger () that is movable along a locking direction (Y) that is perpendicular to the sliding axis, between a locking position in which an end () of the locking finger () is engaged in a groove () of the rod in order to lock the rod in position, and a retracted position in which the end of the finger is disengaged from the groove in order to release the rod, a locking indicator () being secured to the locking finger to be movable between a position indicating locking when the locking finger is in the locking position, and a position indicating unlocking when the locking finger is in the retracted position, the actuator being characterized in that the locking indicator is secured to the locking finger by a connection () suitable for being interrupted in the event of the end of the finger being broken off while the rod is locked, a thrust spring () being arranged in the locking finger to push the locking indicator towards the position indicating unlocking when said connection is interrupted.
