Abstract

Valve, of the type comprising an envelope of generally cylindrical shape, closed by a base, which is hermetically traversed by the axis to which the external governing member, open by the opposite base, is coupled through which it remains in a condition of to be coupled to the element to be fed, and provided with two parallel fittings, protruding radially, arranged to be coupled to the terminals of the two branches into which the corresponding feed pipe is divided, characterized in that inside this the housing is housed in an adjusted manner, being immobilized with respect to displacements in an axial direction, with the possibility of freely rotating between duly established limit positions, a body having on one of its bases a solid axial projection, arranged to pass through in an airtight manner the closed base of the enclosure and receive at its extremity the maneuvering organ, whose body, in a way, is in its lateral surface, it is endowed with a longitudinal cavity closed by its two extremities, and next to it, of two independent cavities, aligned longitudinally, one of which opens on one of the bases or bases of the assembly., while the other is separated from the base or end opposite by a partition or thickness of material, and is, instead, in communication with an axial conduit, which opens to the outside through the end of an axial projection provided in that test; all in such a way that in a limit position in rotation of the inner body, said longitudinal cavity is confronted with the two referred radial fittings, establishing direct communication between them, and preventing circulation to the open base of the enclosure, and, for so much, towards the fed element; while in the opposite limit position, these two fittings, respectively, face one another and the cavities aligned longitudinally, the direct communication between them being interrupted, and directly communicating one of the fittings with the open base of the enclosure, and the other with the axial opening referred to, so that the flow of supplied fluid is forced to circulate in its entirety through the fed element; and there is a succession of intermediate positions between these two limit positions, in which the proportion of flow rate that circulates directly between the side fittings and that which is diverted towards the feed element progressively varies.
