Abstract

Es wird ein Kraftstoffeinspritzsystem für Brennkraftmaschinen vorgeschlagen, daß einen Kraftstoffhochdruckspeicher (8) aufweist, der von einer Kraftstoffhochdruckpumpe (5) mit Kraftstoff versorgt wird und der über ein Druckregelventil (11) auf einen vorgegebenen Druck regelbar ist. Zwischen dem Druckregelventil (11) und dem Kraftstoffhochdruckspeicher (8) ist ein Filter (17) vorgesehen.

Figure 00000001
A fuel injection system for internal combustion engines is proposed which has a high-pressure fuel reservoir (8) which is supplied with fuel by a high-pressure fuel pump (5) and which can be regulated to a predetermined pressure via a pressure control valve (11). A filter (17) is provided between the pressure control valve (11) and the high-pressure fuel reservoir (8).
