Abstract
Description
technical field
[0001] The invention relates to a valve for controlling a fluid. Background technique
[0002] Such a valve is known from EP 0 192 241 . In this case, in particular the injection valves in common rail injection systems are provided with servo valves for controlling the fluid flow. To fuel the internal combustion engine, so-called accumulator injection systems are used, in which systems work with very high injection pressures. Such injection systems are known as common rail injection systems for diesel engines and HPDI injection systems for gasoline engines. In these injection systems, fuel is conveyed via high-pressure pumps into a common high-pressure accumulator, from where the injection valves on the individual cylinders are supplied with fuel. The opening and closing of the injection valves is generally controlled electronically.
[0003] It is known from DE 196 50 865 A1 that a fuel injector has a high-pressure connection which opens laterally into t...
