Abstract:
A transverse or longitudinal thruster for a floating or submersible vessel, associated with means for moving the thruster in and out of a well of longitudinal shape and including means for preventing pivoting about the longitudinal axis ZZ' of the well, comprising a male part extending transversely of axis ZZ' and of a shape complementary to the female shape of the inside of the well in which it slides longitudinally along said axis, and a maneuvering support arm of a cylindrical shape passing through a bearing secured to said well and having a propeller drive shaft rotatably mounted therein, said male part comprising a plate supported by said maneuvering support arm, said support arm supporting at its top end drive means for driving said shaft, the complementary shapes respectively of the bearing and of the support arm serving to guide the support arm with clearance .DELTA..sub.1, between them, which clearance is compatible with a clearance .DELTA..sub.2 obtained, when the thruster is in an extended position, between said transverse male part and an edge of the well, thereby enabling the male part to bear against the edge of the well and to transmit thrust forces to a hull of the vessel.
