Module for an aircraft turbine engine

A module for an aircraft turbine engine, the module having a longitudinal axis and comprising:

• a hub centered on the longitudinal axis and configured to be movable in rotation about the longitudinal axis;
• vanes carried by the hub, each of the vanes being movable about a pitch axis extending radially with respect to the longitudinal axis;
• and
• a device for changing the pitch of the vanes about their pitch axes, the device comprising:
• a hydraulic actuator configured to be movable in rotation about the longitudinal axis and configured to drive the vanes about their pitch axes;
• and
• a supply pump for supplying fluid to the hydraulic actuator, the supply pump comprising:
• axial pistons configured to be movable in rotation about the longitudinal axis and configured to transfer the fluid to the hydraulic actuator;
• a connecting plate connected to the axial pistons and cooperating with an annular main plate centered on the longitudinal axis, the main plate being configured to be stationary in rotation about the longitudinal axis and tiltable relative to the longitudinal axis, the connecting plate being arranged between the main plate and the axial pistons;
• wherein the axial pistons are able to move in translation in a direction parallel to the longitudinal axis, and wherein the tilting of the main plate causes the axial pistons to move in the direction parallel to the longitudinal axis;
• and
• an auxiliary actuator connected to the connecting plate and configured to drive in rotation the connecting plate about the longitudinal axis.
