Abstract (en)

[origin: FR2857705A1] The distributor, consisting of a housing (2) containing a pressure reducer (3), a pusher (5), a distribution channel, a plunger (25), slide valve (30), and return (40) and regulating (50) springs, has a central bore (45) in the pusher that discharges at its lower end (7), with the enlarged head (26) of the plunger moving inside it. The regulating spring is also located inside the pusher bore, between the plunger head and the base of a sleeve (35), so that movement of the pusher causes an expansion of the spring and a reduction in the regulated pressure in output line (22).
