Patent ID: 7891584

Claim:
A fuel injection valve for intermittent injection of fuel into the combustion space of an internal combustion engine, the fuel injection valve comprising: an elongated housing which has a housing body and a nozzle body with an injection valve seat; a high-pressure space which is arranged in the housing and is connected to a fuel high-pressure inlet and the injection valve seat; an injection valve member which is arranged in the housing in a longitudinally adjustable manner and interacts with the injection valve seat; a guide sleeve having a first end face and an opposite second end face; and a closing spring which is supported on a first side on the injection valve member and acts upon the injection valve member with a closing force directed toward the injection valve seat and which is supported on a second side on the first end face of the guide sleeve, the injection valve member being guided solely on the guide sleeve and in a piston-like manner in the guide sleeve in a sliding fit, wherein the guide sleeve is supported with the opposite second end face thereof on a supporting body and in the process presses the supporting body against the housing as to seal the high-pressure space, and wherein a fuel feed channel that is connected to the fuel high-pressure inlet opens into an annular gap between the guide sleeve and the housing, and wherein the guide sleeve has a centering element at the first end face for centering relative to the housing and at least one passage in the vicinity of the first end face for a hydraulic connection of the annular gap and a part of the high-pressure space that lies between the guide sleeve and the injection valve seat.
