Now, therefore, at least the following is claimed: 1. 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. 2. The appliance (1) according to claim 1, wherein the open position is an indexed position. 3. The appliance (1) according to claim 1, wherein the decompression position is an indexed position. 4. The appliance (1) according to claim 1, further comprising a pressure regulation valve (11A), said valve (11A) forming the setting means (11). 5. The appliance (1) according to claim 4, wherein the setting means (11) is in at least one indexed regulation position, wherein, firstly, it substantially prevents any connection of the inside of the chamber to the outside while the pressure applied in the chamber is less than a predetermined regulation pressure and, secondly, it connects the inside of the chamber with the outside once the pressure applied in the chamber has substantially reached said predetermined regulation pressure. 6. The appliance (1) according to claim 1, wherein the cooking chamber is subjected to the effect of a heating source, the setting means (11), when it is in its decompression position, setting the inlet section (8) and flow section (9) to enable the quickest possible decompression of the chamber to the predetermined safety pressure, without substantial projection of foods outside the appliance (1) without switching off the heating source. 7. The appliance (1) according to claim 1, wherein the inlet section (8) and flow section (9) are oriented substantially at an angle with respect to each other, and are preferentially oriented substantially transversally with respect to each other. 8. The appliance (1) according to claim 1, further comprising a vessel (2) and a lid (3) mounted on the vessel (2) to form the cooking chamber, said lid (3) comprising an internal face (3A) located opposite the vessel (2), and an opposite external face (3B), oriented toward the outside of the vessel (2). 9. The appliance (1) according to claim 8, wherein the setting means (11) is fitted in a sliding configuration onto the lid (3). 10. The appliance (1) according to claim 9, wherein the setting means (11) further comprises a cylindrical body comprising at least two segments (12, 13) separated by a shoulder (14), said shoulder (14) taking part in the setting of the flow section (9), while at least one of said segments (12) takes part in the settings of the inlet section (8). 11. The appliance (1) according to claim 10, wherein the cylindrical body further comprises at least a first, a second and a third segment (12, 12A, 13), said first and second segments (12, 12A) being separated by a first shoulder (12B), said second and third segments (12A, 13) being separated by a second shoulder (14), said cylindrical body being arranged with respect to the pipe such that, firstly, the first and second segments (12, 12A) take part in alternation in the setting of the inlet section (8), and that, secondly, the second shoulder (14) takes part in the setting of the flow section (9). 12. The appliance (1) according to claim 8, wherein the adjustment device (7) further comprises a leakage orifice (15), provided in the lid (3) and forming an access opening to the leakage pipe, the inlet section (8) being defined by the cooperation of the leakage orifice (15) with the setting means (11). 13. The appliance (1) according to claim 11, wherein with the setting means (11) in the indexed open position, the first segment (12) is inserted into the leakage orifice (15), such that the inlet section (8) has a first annular shape. 14.
