Abstract
The invention relates to a fan module with variable-pitch blades for a turbomachine, comprising a rotor () carrying blades (), a stationary housing (), a mechanism () for regulating the pitch of the blades (), which is connected to the rotor, and a control means () mounted on the stationary housing () and comprising a control part () that can be moved in translation according to an axis (X) of rotation of the rotor (), and a bearing () for load transfer between the control part () and said mechanism, characterised in that it also comprises a stationary track () supporting the elastic restoring means () which are arranged so as to exert an axial restoring force on the control part () towards a determined position, preferably corresponding to the blade () feathering.
