Abstract
This device is for the tight crossing of a partition or bulkhead by a mobile member. The object of the invention is to supply a device permitting the transfer of simultaneous, complex mechanical movements through a tight partition, whilst maintaining the seal of the partition. This object is achieved with the aid of a device having at least one shell or sleeve (4) mounted on a partition so as to pivot about a pivoting axis perpendicular to the crossing axis of the partition by the member and the displacement direction of the member. The member passes in the interior of the sleeve. A plate (12) is tightly traversed by the member (10) and mobile with the member for its displacements in the displacement direction. First and second tight membranes (14 and 16) tightly connect the plate (12)/sleeve (4) and sleeve (4)/partition (8).
