Abstract (en)
[origin: WO9108386A1] A fuel injection pump for internal combustion engines has an adjusting piston (11) for adjusting the injection timing which delimits a working space (14) in a cylinder (12). A mobile spool valve (18) which is actuated by a supply pressure is arranged in a blind bore (17) in the adjusting piston (11) and delimits a compression chamber (21). Depending on the setting of the spool valve (18), the working space (14) is connected to the compression chamber (21) or to a discharge chamber (15). The feed pressure is generated by a pump (33) and modified by a solenoid valve (46) in an outlet line (44) in function of operating parameters of the internal combustion engine in such a manner that the injection timing is adjusted in function of the operating parameters.
