Abstract
This connecting device applies to a sealed connection device in which, firstly, each chamber, respectively a stationary chamber “A” and a transportable chamber “B” has at least one access opening equipped with a door (2, 3) cooperating with a flange (4, 5) with the interposition of sealing elements (12, 14), one (2) of the two doors being articulated to its flange (4), and secondly, the two doors (2, 3) have an element to lock their respective flanges (4, 5) and complementary connecting elements which allow them to be connected thereby forming, through contact of sealing elements (12, 16), an internal space “C” isolating their faces (17, 18) opposite each other from the external medium. The elements of connecting the two doors (2, 3) together comprise a network of ducts (30, 34, 35) formed at least in one of the doors and emerging, at one of its ends, from the external face (18) of the said door in the said sealed internal space “C”, the said network being connected, at its other end, to a source (30) of vacuum.
