Abstract:
A fuel injection pump comprising a housing (10), a metering pump (18, 20) and an injection adjuster (26) for the metering pump, said injection adjuster having a piston (28) which is displaceable in a bore (30) that it divides into work chambers (32, 34) separated from one another, said piston (28) being acted upon by a restoring spring (48), a starting spring (50) which acts upon said piston (28) and acts counter to said restoring spring, and a prefeed pump (14) which communicates with said work chambers (32, 34) via supply bores (36, 38), and a control slide (40) and a proportional magnet (42) by means of which the fluid flow through the supply bores (36, 38) can be controlled.
