Disclosed herein is a constant pressure cooker which has a coupling steel ring attached to the peripheries of the cover of the cooker and the cooker body and there is an opening at the coupling ring so that an adjustment of the opening can adjust the tightness of the cooker in its application. The said coupling steel ring has a springband on its upper ring surface or the steel ring itself is made of elastic steel material so that whenever the pressure cooker is tightly sealed and the steam therein has reached its predetermined saturated pressure, there is a upper thrust force, then, the spring band at the coupling steel ring moves upwards or the elastic steel ring expands so that the saturated steam in the cooker is released and the steam pressure in the cooker keeps constant.

A constant pressure cooker, comprising: a cooker body having a protruding edge portion; a cover having an exterior margin curved inward and under the cover to form a cover groove, the exterior margin being shaped so as to mate with the protruding edge portion of the cooker body when the cover is placed on the cooker body; a thermal resistant rubber material placed within the cover groove; and a coupling ring having a gap therein and having a cross sectional shape for clamping the protruding edge portion of the cooker body to the exterior margin of the cover and fabricated from a flexible metal material such that for pressures within the cooker below a predetermined threshold, the edge portion of the body is held tightly to the exterior margin of the cover, but for pressures within the cooker at or above the predetermined threshold, the cross-section of the ring deforms and allows the exterior margin of the cover to separate from the edge portion of the cooker body so that pressurized gases can escape from the cooker; and means for adjusting the size of the gap to clamp and unclamp the coupling ring.
