Abstract

Pressure regulator for hydraulic installations, characterized essentially by the fact that it comprises a calibrated passage valve capable of being gradually closed by an elastically driven shutter by an adjustable spring that acts against the shutter through a diaphragm tightly fitted in a distributor chamber of the regulator, located on the outlet side of the valve, whose calibrated passage presents reduced passages that allow a minimum circulation of fluid when the shutter is closed, while the described distribution chamber communicates with a capacity expander of pressure reduced, as well as a step that communicates with a pressure switch in connection with the operating command of a fluid booster pump, whose pressure switch is graduated to act in the closing direction of the pump when the pressure of the distribution chamber exceeds a value expected to be above the value of the pressure of normal circulation of fluid.
