<p>Hydraulic section (1) comprising: a main spool (2); pressure compensation means (16) able to maintain a substantially constant pressure drop through a metering orifice (3) of said main spool (2); a first chamber (7) interposed between said main spool (2) and a first end (16a) of said compensation means (16); a second chamber (6) situated at a second end (16b) of said compensation means (16), said second chamber (6) being connectable to a feed line (Pal) from a pump (100) by means of a predefined channel (Pp) in such a way that said hydraulic section (1) operates as a priority section, or being connectable to a line (LS) for detecting the highest load pressure in such a way that said hydraulic section (1) operates as a flow-sharing section.</p> |
