Abstract (en)
[origin: WO2010142611A1] The invention relates to a characteristic-map-controlled lubricant pump system (1) comprising a lubricant pump (2) for supplying an internal combustion engine (3) with lubricant, wherein the lubricant pump (2) is controlled by a proportional valve (6), an actuating unit (9), which is arranged in the lubricant pump (2) and preloaded by a spring (10), a first pressure chamber (11) acting on the actuating unit (9), which first pressure chamber is arranged in the lubricant pump (2) and is pressurized in a characteristic-map-controlled manner and thereby moves the actuating unit (9) toward the spring (10) and upstream of which first pressure chamber the proportional valve (6) is arranged, at least one second pressure chamber (12,12') acting on the actuating unit (9), which at least one second pressure chamber is arranged in the lubricant pump (2) and is likewise pressurized and thereby moves the actuating unit (9) toward the spring (10), wherein the at least one second pressure chamber (12,12') has smaller dimensions than the first pressure chamber (11), wherein, if the proportional valve (6) fails, the lubricant pump (2) is pressurized exclusively by means of the at least one second pressure chamber (12,12').
