Abstract: A pressure cooking appliance arranged to form a cooking chamber and comprising an adjustment device (7) of the pressure inside the chamber, which comprises a steam leakage pipe, said pipe defining a steam inlet section (8) and a flow section (9), wherein the adjustment device (7) comprises setting means (11) of the inlet section (8) and flow section (9), which is mobile between an open position, wherein it sets the inlet section (8) and flow section (9) so as to prevent the pressure applied inside the chamber from rising above a safety pressure and a decompression position, wherein it sets the inlet section (8) and flow section (9) to enable the decompression of the chamber to the safety pressure, without food projection.

Abstract: A lip gasket (1) designed to be mounted between the lid (2) and the bowl (3) of a cooking appliance (4) for the purpose of providing sealing between the lid (2) and the bowl (3), the gasket (1) comprising at least first and second lips (1A, 1B), interconnected by a heel, the lips (1A, 1B) and the heel (1C) being such that, when the lips (1A, 1B) are brought together, they are suitable for defining a closed interstitial space (100), the gasket (1) being characterized in that it is provided with at least one geometrical discontinuity (80) suitable for acting, when the lips (1A, 1B) are brought together, to provide at least one path (9, 90) for putting the interstitial space (100) into communication with the outside. The invention applies to household cooking appliances.
