Abstract There is described a regulator and control device for pressure cookers particularly for cookers with a bayonet type closure. The device has a body and a lid to which respective sideways projecting semi-handles are connected which are coupled on closing and separated on opening. The top handle includes an adjustable valve unit and a safety element which strains the joint made between body and lid when the cooker is open. The device is characterized in that the valve unit, comprising basically a bracket with two sectors with different diameters, forming a stepping through which its top half is coupled to the mouth of the hole in the lid, while its bottom threaded half holds a locknut. The bracket has a radial fin in its top half through which, with the aid of a screw, it is fixed to the head of the top handle, whereas the locknut which actually forms part of the valve has an annular spherical seat in a narrow bottom part, for an axial sealing plunger which crosses the bracket, and which includes a seat with respect to the above, the plunger thus forming an annular chamber with regard to the bracket and immediately above its seat, the annular chamber being communicated by a steam outlet nozzle placed between the head of the handle and the lid, opposite the arm of the former, with the particularity that this plunger is projected against the nut by a spring arranged between a stepping in it and the partially restricted opening of a bushing mounted and sliding inside the bracket, to be exact, in its top or outer half.
