ABSTRACT:
A pressure cooker in which a pressure vessel (1) and a lid (2) are associated with each other by means of a bayonet-type closure system (4, 5) is provided with a sealing gasket (3) fitted between the pressure vessel and the lid and with a controlled leakage device having a push-rod (8) mounted on the lid (2). The sealing gasket (3) has at least one groove (11) parallel to one edge of the gasket in a lateral face which is directed towards the pressure vessel (1) externally of this latter. When the sealing gasket (3) is displaced by the push-rod (8), the groove (11) establishes a calibrated leakage flow between the interior and the exterior of the pressure vessel.
