Patent ID: 7703385

Claim:
A food pressure cooking appliance ( 1 ) arranged to form a cooking chamber designed to be pressurized, said appliance ( 1 ) comprising: an adjustment device ( 7 ) of the pressure inside the chamber, said device ( 7 ) comprising: a leakage pipe used to establish a steam leakage flow from inside the chamber to outside the appliance ( 1 ), said pipe defining a steam inlet section ( 8 ), through which the steam contained in the chamber enters the pipe, and a flow section ( 9 ), located downstream from the inlet section ( 8 ); and setting means ( 11 ) of the inlet section ( 8 ) and flow section ( 9 ), said setting means ( 11 ) being mobile between at least, firstly, an open position, wherein it sets the inlet section ( 8 ) and flow section ( 9 ) to enable a steam leakage via the pipe while preventing the pressure applied in the chamber from rising above a predetermined safety pressure, and, secondly, a decompression position, wherein it sets the inlet section ( 8 ) and flow section ( 9 ) to enable decompression of the chamber to the predetermined safety pressure, without substantial projection of foods outside the appliance ( 1 ) and in which said open position and said decompression position provide a continuous steam leakage flow.
