  • Patent number: 5850778
    Abstract: Cookers working with an increasing internal pressure require a pressure indicator which can also adjust the internal pressure to a certain extent and, especially in the event of excessively high internal pressure, to release it by pressure equalization with the environment. Such pressure indicators consist of many parts and are complicated and not easily handlable for cleaning purposes. The invention proposes a pressure indicator which may consist of only a single component (2) besides the pressure indicator pin (1), being made of an elastic material and is multifunctional.

  • Patent number: 5724884
    Abstract: 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.
