Claims17
A lid for a pressure cooker with a removable lid handle, comprising:
- a technology module that has movable operational elements needed for the function of the pressure cooker;
- a masking module that masks the technology module;
- wherein the technology module comprises at least one of the operational elements of the group including:
- a pressure display device;
- a lid lock;
- a movable sealing element of a working valve for selecting different pressure levels in the pressure cooker;
- a compression spring that acts upon the movable sealing element with an adjustable compressive pressure;
- and an adjustment device for changing the compressive pressure on the compression spring on the sealing element;
- and
- wherein the adjustment device for changing the compressive pressure on the sealing element comprises a rotating mechanism, and wherein, depending on the rotational movement, one end of the compression spring is acted upon with a pre-determined force in such a way that a certain force is exerted on the sealing element by the other end of the compression spring.

A lid for a pressure cooker with a removable lid handle, comprising:
- a technology module that has movable operational elements needed for the function of the pressure cooker;
- a masking module that masks the technology module;
- a sealing element provided around an area around a pressure-relief valve, wherein the sealing element seals the lid's upper side with respect to the technology module, and has an opening through which the steam escaping from the pressure-relief valve can be dissipated in one of a lateral direction and to a front of the cooker.
