A valve is needed in a cooking utensil operating with an increased internal pressure, which valve is at the same time also capable of regulating the internal pressure, and, in particular, takes care that a nonpermissibly high internal pressure is reduced through a pressure release with the outside.

A valve is needed in a cooking utensil operating with an increased internal pressure, which valve is at the same time also capable of regulating the internal pressure, and, in particular, takes care that a nonpermissibly high internal pressure is reduced through a pressure release with the outside. Such valves are designed with many parts and are complicated and are difficult to handle also during cleaning. The invention provides a valve, which is manufactured essentially of a single piece of a rubber-elastic material, and permits at the same time to carry out all of the necessary functions.

[ The invention claimed is:] [1.] In a valve for a cooking utensil which is adapted to be operated with excess pressure and closed with a lid, comprising a valve member arranged in a valve opening provided in the lid, said valve member being axially aligned and moveable within said valve opening, the improvement comprising said valve member having a valve piston, said valve piston having means for indicating the pressure provided outside of the cooking utensil, a control collar for controlling said valve opening, said control collar being larger in diameter than said valve and into engagement with an inside surface of said lid encircling said valve opening and axially movable with respect to said valve opening in response to a pressure in the cooking utensil and is initially maintained oriented within the cooking utensil, and a stop piece constantly remaining within the cooking utensil, said stop piece partly covering said valve opening and contacting said lid when said control collar has passed through said valve opening, and at least said control collar consisting of an elastic material so that it can be urged through said valve opening to a location outside of the cooking utensil in response to the pressure in the cooking utensil exceeding the operating pressure, said axial movement orienting said control collar outside of the cooking utensil being stopped by said stop piece contacting an inside surface of said lid.
