ABSTRACT:
A pressure cooker has a lid displaceable in the vertical direction with respect to the cooker to reduce the residual pressure in the cooker and to permit opening of the cooker without any rotary movement. Tongues projecting downwards between the dome edge and the cooker edge, in conjunction with guide slots provided in clips which hold together the cooker and the lid ensure radial opening and closing movements of the clips. A centering ring located in the dome and extending into the cooker facilitates the engagement of the lid on the cooker. The centering ring carries the sealing ring and the tongues and is based away from the dome by springs supported on the dome. The dome and the centering ring are guided on one another by interengaging elements and can be locked together in the open position. On closing the pressure cooker, the locking action is eliminated and the springs bring about both the closing displacement of the clips and also the positioning of the sealing ring with respect to its sealing surfaces on the dome and the cooker.
