摘要

The cooker has a lower part connected with an upper part using a bayonet fixing unit, which is designed as dual-, triple-, and quad-bayonets. A residual pressure securing unit is provided to prevent loosening of connection between the upper part and the lower part within a defined pressure. An overpressure valve is integrated in the residual pressure securing unit. A handle is arranged at the upper part, and the overpressure valve is designed as a two chamber-safety valve, which is partially made of plastic i.e. silicone.
