ABSTRACT:
The pressure regulator comprises a valve with a slide member (5) whose displacements are controlled by the pressure prevailing in the control chamber (7). This pressure is adjusted by an obturator (11) of tubular shape which, in its upper position, places the chamber (7) in communication with the opening (4) of the fluid outlet. The fluid is admitted into the valve by an opening (2) and the displacements of slide member (5) permit adjusting the pressure in the opening (3) which supplies a user. The control chamber (7) is fed from the opening (3) through a conduit (20) with fluid whose pressure is already adjusted.
