A pressure cooker (1) with additional safety device against the danger of explosion due to overpressure, comprising a vessel (2) which is open upward, a lid (3) which can engage the mouth (7) of the vessel (2) in order to close it, and an annular gasket (4) which is associated with the lid (3) and can engage the inner lateral surface (2a) of the vessel in order to provide the steam-tight seal between the vessel (2) and the lid (3); the gasket (4) has at least one portion (5) that can be deformed due to the pressure that acts on its side directed toward the inside of the vessel (2) in order to pass from a sealing position, in which it is engaged hermetically with the inner lateral surface (2a) of the vessel (2) and with the lid (3), to a venting position, in which it is disengaged from the inner lateral surface (2a) of the vessel (2), in order to allow the outward venting of steam when a preset pressure is exceeded inside the vessel (2). |
