Patent ID: 7066150

Claim:
A fuel injection system for internal combustion engines, comprising a fuel injection valve, which is supplied by a high-pressure fuel source and which has a valve member ( 32 ) that is adjustable by means of the pressure of a pressure chamber ( 31 ) embodied in the fuel injection valve and thereby controls an injection opening ( 38 ) that can be made to communicate with the pressure chamber ( 31 ), a control valve ( 50 ), which has a control valve member ( 54 ) which, in a first position, disconnects a first pressure chamber ( 57 ) that continuously communicates with the high-pressure fuel source from a supply line ( 28 ) leading to the pressure chamber ( 31 ), and in a second position, opens the communication between the high-pressure fuel source and the pressure chamber ( 31 ), and a line ( 17 ) having a throttle ( 72 ) between the high-pressure fuel source and the first pressure chamber ( 57 ), the line ( 71 ) leading to an otherwise closed damping chamber ( 70 ), wherein the damping chamber ( 7 ) is disposed inside the fuel injection valve.
