| 摘要 |
The invention relates to a volume flow control valve (11), particularly for a fuel injection system such as a common rail system operated by means of a pressurized fluid, especially diesel fuel. Said volume flow control valve (11) comprises a hydraulic part (1) with a hydraulic bush (80) that has a jacket (801), and a control part (2), especially an electromagnetic control part, which cooperates with the hydraulic part (1) and is used for controlling the volume flow penetrating the volume flow control valve. The volume flow control valve can be controlled between an open and a closed position via different intermediate positions. The jacket (801) of the hydraulic bush (80) is fitted with at least two through-holes (3, 4) for the fluid in order to improve the fine control behavior of the volume flow control valve (11). The invention further relates to methods for improving the fine control behavior of a volume flow control valve as well as fuel injection systems comprising a volume flow control valve (11) according to the invention or a volume flow control valve operating according to the disclosed method. |
