摘要

The unit (10) has a motor (14) adapted to drive a turbine (15) of the unit. A motor support (12) and the motor are fixed with respect to each other by a bayonet device. The bayonet device includes axial stops i.e. crowns, placed on the motor support and axial stops i.e. studs, arranged on the motor. The axial stops are adapted to be in abutment against each other by translation of the motor with respect to the motor support according to a bayonet axis (A) to block the translation of the motor with respect to the motor support in a direction of the bayonet axis.
