摘要

The high-pressure fuel pump (1) has a pump housing and a housing flange arranged in a housing bearing (6). The flange bearing (5) is mounted in a pump drive shaft (4). The storage chokes (7a,7b) are arranged between the housing bearing and the flange. The fuel is passed through the storage chokes. The storage chokes are parallelly arranged to the throttle bearing, and are provided with the flow-determining units (8a,8b). The flow-determining unit is arranged between the thrust bearing and the radial bearing.
