Claims18
A regulation and control device for pressure cookers which, being specially designed for cookers with bayonet type closures, to whose body and lid respective semi-handles are connected, projecting sideways, which are coupled on closing and separated on opening, the top handle including an adjustable valve unit and a safety element which strains the joint made between the body and the lid when it is opened, 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. Said 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, said plunger thus forming an annular chamber with regard to the bracket and immediately above its seat, said 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.
