摘要：
A high pressure fuel pump encompasses at least one delivery chamber and one high pressure outlet. in addition, a pressure limiting valve with a valve that is actuated by a pressure differential is provided that can open from the high pressure outlet to the delivery chamber. On a high pressure side of a valve seat of the pressure limiting valve, it is advantageous that a throttle device is provided, whose free cross section is at most approximately equal to a desired maximum opening cross section of the pressure limiting valve.
