Abstract
A multi-axial positioning system of unitary construction design selectively moves a port door along two transverse paths of travel toward and away from the aperture of a port plate. The positioning system includes a link carriage operatively connected to a drive mechanism that moves a drive carriage along a first travel path. A pivot link structure causes the link and drive carriages to move in unison for a distance along the first travel path. A guide prevents the link carriage from moving past a location along the first travel path, and, in response, the pivot link pivotally moves to cause the link carriage to move along a second travel path and thereby move the port door toward or away from the port plate aperture, depending on the direction of movement of the drive carriage along the first travel path relative to the link carriage.
