Abstract

Pressure regulator for pneumatic installations, with elastified piston sensitive to the pressures of the compressor and user powered by said compressor and functionally connected to an interception organ that controls the communication of the output of said compressor respectively with the discharge and with said user, characterized by a differential piston influenced by adjustable elastic means and delimiting three pneumatic chambers, the first of which is interested by the piston of smaller surface of said differential piston and is connected directly to the user's connector; by means of interception, adjustable independently of the elastic means of said differential piston and which control the communication between the first two chambers of the three mentioned, in order to apply to the face of greater area of said differential piston the pressure existing in the first camera; by other means of interception to control the communication between the second chamber and the discharge and functionally connected to said differential piston for its operation during the displacements made by the latter and thus quickly establish in the second chamber pressures that respond to the maximum and minimum regulated that act on the user and that, driving the second mentioned interception organ, connect or not and with spring control, the output of the compressor with the user or with the discharge.
