Abstract

Die Erfindung betrifft ein Kraftstoffeinspritzsystem umfassend, eine Kraftstoffhochdruckpumpeneinheit (1, 2), mit einer Kraftstoffvorförderpumpe (1) und einer Kraftstoffhochdruckpumpe (2), ein der Kraftstoffhochdruckpumpeneinheit (1, 2) vorgeschaltetes Kraftstofffilter (4) und eine Entlüftungsvorrichtung (5), die zwischen der Kraftstoffhochdruckpumpeneinheit (1, 2) und dem Kraftstofffilter (4) angeordnet ist, wobei die Entlüftungsvorrichtung (5) als Wegeventil (5') ausgebildet ist. Das Wegeventil (5') vereint die Entlüftungsfunktion mit einer Temperaturmessung des Fluidstroms. Hierzu umfasst das Wegeventil (5') einen Temperatursensor (6).

The invention relates to a fuel injection system comprising a high - pressure fuel pump unit (1, 2) with a fuel feed pump (1) and a high - pressure fuel pump (2), a fuel filter (4) upstream of the high - pressure fuel pump unit (1, 2) and a venting device (5) between the high-pressure fuel pump unit (1, 2) and the fuel filter (4) is arranged, wherein the venting device (5) is designed as a directional control valve (5 '). The directional control valve (5 ') combines the venting function with a temperature measurement of the fluid flow. For this purpose, the directional control valve (5 ') comprises a temperature sensor (6).
