Patent ID: 6840219

Claim:
A fuel delivery system for an internal combustion engine comprising a fuel feed pump ( 10 ), which delivers fuel which is at pilot pressure to a high-pressure fuel pump ( 11 ) that communicates on the high-pressure side with at least one injection valve ( 14 ), in order to deliver fuel at high pressure to the injection valve or valves ( 14 ), and means for delivering a coolant medium flow to the high-pressure fuel pump ( 11 ) via at least one coolant conduit ( 21 , 31 ), in order to keep the temperature (T HDP ) of the high-pressure fuel pump ( 11 ) below a critical operating temperature (T k1 ), said means for delivering a coolant medium flow including means for controlling the coolant medium flow as a function of the temperature of the high-pressure fuel pump ( 11 ) and the critical operating temperature (T k1 ).
