<p>This regulator comprises a lamellar internal chamber (8), without projections or recesses, an axial inlet orifice (9), an outlet orifice (14) at its upper part, and a purging orifice (15) at its lower part, closed off by a sliding piston (16). The freeing of the purging orifice (15) by the inward sliding of the closing-off piston is controlled by compressed air penetrating at (20) and acting on the piston (21) integral in translational motion with the closing-off piston (16), and its closing off by the closing- off piston (16) sliding in the opposite direction is brought about by the antagonistic action of the return spring (22). <IMAGE></p> |
