Patent ID: 7401593

Claim:
A high-pressure fuel pump ( 30 ) having a delivery chamber ( 60 ) delimited on one side by a piston ( 62 ) of the high-pressure fuel pump ( 30 ), the delivery chamber ( 60 ) being connected on the intake side via an intake valve ( 34 ) to a low-pressure fuel line ( 22 ) and on the pressure side via a high-pressure connection ( 63 ) to a high-pressure fuel line ( 42 ), wherein a check valve ( 44 ) and a pressure relief valve ( 56 ), connected parallel to the check valve ( 44 ), are provided between the delivery chamber ( 60 ) that is contained in a housing ( 58 ) and the high-pressure connection ( 63 ) that is connected to the housing ( 58 ) in a fluid-tight manner, both the check valve ( 44 ) and the pressure relief valve ( 56 ) having a center line disposed at approximately 90° to a center line of the piston ( 62 ), wherein the pressure relief valve ( 56 ) is contained in a blind hole bore ( 69 ) of the housing ( 58 ), and wherein the blind hole bore ( 69 ) starts from a chamber ( 68 ) delimited by the high-pressure connection ( 63 ) and the housing ( 58 ).
