Hydraulic section (1) for use in a hydraulic distributor (10) comprising:
a valve body (2) with a main spool (3);
a piston (11);
a flow regulating element (21) receiving the hydraulic fluid coming from a front chamber (30), the piston (11) having a head (12a) of the stem (12) engaged in the flow regulating element (21);
an intermediate chamber (16) delimited by the stem (12) of the piston (11);
control means (6, 7, 18) operatively active on the intermediate chamber (16) to alter its pressure so that the combined piston (11) - regulating element (21) system goes from a balance condition, in which the regulating element (21) is inactive, and a decoupling condition, in which the pressure of the front chamber (30) is decoupled from the pressure of the intermediate chamber (16). |
