Abstract: An inlet section for use in a hydraulic distributor including a valve body and a slider with a first area and a second area. The inlet section further including said slider being longitudinally slidable within the valve body between a first position in which it prevents passage of fluid from a high pressure line to a low pressure line, and a second position in which it enables passage of fluid. The inlet section further including a main spring active on the second area of the slider in a direction consistent with action of the second pressure and a control device of the slider. The control device of the slider includes a mechanical actuator member selectively active on the slider in a direction consistent with the action of the first pressure on the first area of the slider so as to force the slider in the second position.

Abstract: Hydraulic section (1) for use in a hydraulic distributor (10), comprising: a valve body (2); a main spool (3); pressure compensator (5) housed in a first hole in the valve body (2); a piston (11) housed in the first hole; an intermediate chamber (16) in fluid communication with the feed line (Pal), the intermediate chamber (16) extending at least partially in the first hole and being delimited by the rod (12) of the piston (11); two limiters (6, 7) and a drainage channel (18) pertaining to the intermediate chamber (16) for altering the pressure thereof and close the compensator (5).

Abstract: Power unit (101) comprising: a tank (104) for hydraulic oil; an electric motor (105); a power pack body (102) inside of which a hydraulic circuit extends; a hydraulic pump (103) integrated in a cavity (102a) of the power pack body (102).

Abstract: Hydraulic section (1) including: a main spool (2);a pressure compensator (40;4) able to maintain a substantially constant pressure drop through a metering orifice (3) of the main spool (2); a first chamber (7) interposed between the main spool (2) and a first end (16a) of the compensator (40;4) and a second chamber (6) situated at a second end (16b) of the compensator (40;4), the second chamber (6) being connectable to a feed line (Pal) from a pump (100) by a predefined channel (Pp) in such a way that said hydraulic section (1) operates as a priority section, and being connectable to a line (LS) for detecting the highest load pressure in such a way that the hydraulic section (1) operates as a flow-sharing section.
