Abstract (en)
[origin: EP1985853A1] The radial piston pump for common rail injection systems has an eccentric shaft (6), around which tipping segments (5) are fitted which are pivoted on plungers (4) connected to the pump pistons (3). As they tip liquid wedges are formed on which they float. The combination of cylinder (2), piston, piston rod, helical spring, leaf spring and valves (9, 10) is fitted as a single sealed unit in the pump casing (1).
