<p>The invention relates to a distributor of a fluid coming from a first source (11) of high-pressure fluid, under two-fluid control, comprising, in a blind bore (1) formed in a body, a sliding piston (3) defining, with a plug of the bore, a first control chamber (5) connected to a first control fluid source, while a slide (9) provides communication between the first high-pressure fluid source (11) or a low-pressure fluid reservoir (13) and an outlet channel (15) for the distributed fluid. …<??>According to the invention, the bore (1) and the piston (3) are stepped in a corresponding fashion, so as to define between themselves a reaction chamber (25) that is connected permanently to the outlet channel (15), and a second control chamber (21) is formed between the slide (9) and the piston (3) and is connected to a second control fluid source. …<??>The second control fluid source is preferably operated by a solenoid valve (51). …<IMAGE>… </p> |
