Abstract:
A high-pressure fuel pump with a variable delivery quantity for an internal combustion engine, comprising a piston (10) actuated by a camshaft (12) wherein the piston (10) aspirates fuel from a low-pressure line (15) into a pumping chamber (14) and then pumps it into a high-pressure line (16), and a quantity control valve (19) connecting the pumping chamber (14) and the low-pressure line (15), and a separate suction valve (18) disposed between the low-pressure line (15) and the pumping chamber (14), the regulation of the delivery quantity being effected by opening the quantity control valve (19) during the pumping stroke of the piston, wherein said quantity control valve (19) is a magnet valve that is open when without current.
