Pressure regulating valve, to automatically maintain a pressure of a fluid in a proportion, determined essentially constant, in relation to the pressure that reigns in a source of supply where it comes from; which comprises, in combination, a cylinder with an internal end arranged to connect it to an apparatus to be subjected to the lowest pressure; an admission in the wall of the cylinder arranged for its connection with the supply source of the pressurized fluid; a piston housed in the cylinder; a cavity extending from the outer end of the plunger to near its inner end; a piston that lodges in the cavity; a spring that pushes the piston toward the inner end of the cylinder; a first hole in the wall of the piston, which can communicate with the admission in all the axial movement allowed of the piston; a second hole in the wall of the piston, closer to its external end, which can be discovered by the piston in a distance that depends on the relative axial settings of the piston and piston; and ducts communicating the second hole with the inner end of the cylinder, and also with a peripheral overflow groove in the plunger, which is open to a discharge duct in a tract that depends on the axial position of the plunger in the cylinder.
