Abstract
A hatch intended for an autoclave or a similar pressure vessel for movement in two directions at an angle to each other provided with a plurality of eccentrically mounted members. These members are joined to each other for common pivotal movements between two end positions in planes at an angle to the plane of the hatch, are in engagement with a guide in front of the hatch and extending to one side of the pressure vessel opening, are at one of their pivotal end positions reciprocably displaceable together with the hatch while carrying it in said guide, and are at the other of their pivotal end positions engageable against the hatch with support in the guide for inserting the hatch into and locking the hatch against the pressure vessel opening and similarly with support in the guide displacing the hatch reciprocally in its direction at least substantially coinciding with the geometrical axis of the pressure vessel opening during pivotal movements of the eccentric members between said both pivotal end positions.
