Abstract (en)
[origin: WO2004040128A1] The invention relates to a high-pressure fuel pump (10), in particular a radial-piston pump, in which the suction valves (35) are configured as ball valves. This has a positive effect on the efficiency of the high-pressure fuel pump (10). In addition, the use of ball valves simplifies the production and assembly of the inventive high-pressure fuel pump (10).
