Beschreibung
Zusammenfassung:	Multi-purpose hydraulic system (10) for a motor vehicle, which comprises a primary hydraulic circuit, a secondary hydraulic circuit and a diverter valve (5). The primary hydraulic circuit comprises a primary hydraulic pump (1) and at least one primary using device (3) communicating with a delivery duct (lb) of the primary hydraulic pump (1). The secondary hydraulic circuit comprises an electrically actuated secondary hydraulic pump (4) and at least one secondary using device (6) communicating with a delivery duct (4b) of the secondary hydraulic pump (4). The diverter valve (5) is applied to the delivery duct (4b) of the secondary hydraulic pump (4) and is configured to connect selectively and alternately the delivery duct (4b) of the secondary hydraulic pump (4) to the at least one secondary using device (6) or to the at least one primary using device (3) depending on the operation status of the primary hydraulic pump (1). The diverter valve (5) is an automatic hydraulic valve configured to open towards the at least one secondary using device (6) when the primary hydraulic pump (1) is in operation owing to the hydraulic pressure generated by the primary hydraulic pump (1) in the primary hydraulic circuit.
