(57) An electrohydraulic device for driving and remotely controlling a hydraulic distributor
of a directional valve for pressurizing or connecting to the discharge a pair of user
devices comprising: two proportional electric valves (1, 2), which are fed by a pressure
line (P), have a discharge line (T), and are connected respectively to opposite end
chambers (M, N) of a hydraulic distributor (6) adapted to pressurize or connect to
the discharge (T) two user devices; remote control means adapted to generate an electric
control signal to energize electromagnets (11, 12) of the electric valves (1, 2);
and an electronic circuit (5a, 5b) adapted to control and adjust the energization
current of the electromagnets as a function of the electric control signal; the energization
current drives the electromagnets (11, 12) for the selective feeding of the chambers
with a preset pressure or for their connection to the discharge across the electric
valves in order to move the slider (3) of the distributor (6) proportionally to the
energization current; the electronic circuit is integrated in the body that houses
the hydraulic distributor.
