High-pressure pump e.g. radial piston pump, for air-compressing, self-ignition internal combustion engine, has pump-connection point whose throttling effect is greater than throttling effect at another pump-connection point

摘要

The pump (1) has a metering-connection point (3) connected with a distribution channel (6). Pump-connection points (11, 12) are arranged close to the metering-connection point, for respective pump groups (14, 15) e.g. plug-in pumps. The distribution channel allows unthrottled connection of the metering-connection point with the pump-connection points. The pump-connection point (11) includes a branch channel (17) branched off from the distribution channel, where throttling effect at the pump-connection point (11) is greater than throttling effect at the pump-connection point (12).
