Abstract

The invention refers to a mechanical combustion-engine-driven fluid pump (10) comprising an input shaft (20) which is directly driven by the combustion engine (12), a pumping unit (18) with a pump rotor (19), and a clutch (16) between the input shaft (20) and the pump rotor (19). The clutch (16) is a magneto-rheological clutch (16) comprising a fluid gap (26) between two clutch bodies (22, 24), whereby the fluid gap (26) is filled with a magneto-rheological fluid (28). A shiftable permanent magnet element (30) is provided, whereby the permanent magnet element (30) is shiftable between an engaged position, wherein the permanent magnet element's magnetic field penetrates the gap (26) with high magnetic flux, and a disengaged position, wherein the magnet element's magnetic field penetration flux is less than in the engaged position. An actuator (42) is provided for moving the permanent magnet element (30) between its engaged and its disengaged position. The magneto-rheological clutch is failsafe.
