Abstract
The present invention relates to a device for actuating in particular oil-dynamic distributors of the type used in hydraulic circuits. It comprises a hydraulic driving actuator 3 which directly performs axial displacement of the sliding piece (or shuttle) 41 of a distributor. The actuator 3 consists of a small hydraulic cylinder of the single-acting type operated by means of a servo solenoid valve 2 which is able to supply the cylinder 3 with a variable pressure. The servo solenoid valve 2 comprises a sliding piece provided with two different cylindrical portions 22 and 29, (axial) operation of which is obtained by means of an electromagnet 27 which acts directly on a movable element 21 fixed to the sliding piece itself. <IMAGE>
