<p>A steam-pressure cooking utensil has a utensil and a lid which are both connected with one another by a bayonetlike or similar lock. A cooking and safety valve is arranged in the lid, and includes a valve member which is connected to the lid and a valve which is held pressed against a valve seat by means of a spring. Furthermore, the steam-pressure cooking utensil has a locking mechanism which permits relative rotation of the lid and utensil and thus an opening thereof only after the pressure in the utensil has been removed. In order to permit in the steam-pressure cooking utensil the steam-removal and unlocking, or to permit the closing of the cooking and safety valve and the locking, in a manner assuring that no residual pressure exists in the utensil during opening, the valve is provided with a receiving arrangement, into which extends an operating member which is connected rigidly with the locking mechanism in a manner so that, during an unlocking of the lid and utensil, the valve is automatically lifted off its seat against the spring tension, while during locking of the lid the valve is placed on its seat.</p> |
