ABSTRACT:
An autoclave, to be used as a pressure cooker or a sterilizer, has a cylindrical vessel centered on a horizontal axis with open ends rimmed by radially inwardly projecting shoulders reinforced by rings with axially outwardly converging resilient external flanges and axially inwardly diverging resilient internal flanges forming small-diameter outer annular seats and large-diameter inner annular seats. A carriage, axially slidable along a base supporting the vessel, rigidly interconnects an upright internal lid and two upright external lids which are axially separated by a distance corresponding to the spacing of the two end flanges of the vessel, the internal lid coming to rest against one or the other inner seat while a respective external lid lies against the opposite outer seat to seal the vessel, the development of steam pressure within the vessel exerting upon these lids a differential force holding them firmly in their closure position. Upon the venting of the vessel, the carriage can be shifted with introduction of a fresh load into the vessel and removal of the one previously treated. In a simplified embodiment, one of the two external lids is omitted.
