Abstract

An oil pump control system (200; 400) comprising an oil pump (100; 300) and a primary lubrication circuit (101; 301) . The control system (200; 400) is characterised in that it envisages a secondary circuit (102; 302) comprising, in turn, a solenoid valve (114; 303) whose opening/closing is controlled by an electronic control unit. The secondary circuit (102; 302) achieves the adjustment between two values (P*, P**) of the delivery pressure in the primary lubrication circuit (101; 301) to save pumping energy.
