The rear end 31 of the metering piston 3 is connected to a fuel under high pressure up to 2000 bar and above, and is operated by this fuel. The control piston 4 is moved up and down between the two end positions by, for example, an electrically controlled hydraulic driver 6, 61; 7. The control piston 4 has fuel guide elements 41 and 42, through which fuel is supplied from the fuel pads 8 and 81 to the metering piston space 30 or from the metering piston space 30 to the reciprocating piston. The cylinders 52 and 53 of the internal combustion engine 5 are supplied. The control or guide elements 41, 42, ie the grooves and the bores are advantageously arranged, ie connected to the high pressure fuel pumps 8, 81 or to the injection nozzles 51 of the cylinders 52, 53 at any position. It doesn't work.
