Kind Code:
B1
Abstract:
The device comprises a case and a thruster. According to the invention, the case (6) or the thruster (5) comprises at least one flap (17) which is radially moveable between a first normal radial position, wherein the flap does not act as an obstacle to the displacement of the thruster in relation to the case, and a second radial position wherein the flap acts as an obstacle to the displacement thereof. Said flap comprises an opening (22). The thruster (5) or case (6), respectively comprises at least one projection in the form of a ramp (86) which can place the flap in said second radial position, whereupon it can penetrate said opening, thereby enabling the flap to return to the first radial position. The thruster or case also respectively comprises at least one stop area (36) against which the flap (17) rests when it is placed in the second position by the projection, said rest position occurring just before the projection is placed in an opposite position in relation to the opening (22).
