摘要： A nozzle for a fuel injector the nozzle having a pivotably symmetrical nozzle member with a hollow space for introducing a nozzle needle, a nozzle tip at a longitudinal end of the nozzle member, at least one opening channel extending in a straight line for the discharge of fuel, and a nozzle needle arranged in the hollow space for selectively blocking an fuel inflow to the at least one opening channel. The nozzle is characterized in that the at least one opening channel has a center axis that is skewed with respect to the longitudinal axis of the nozzle member.

摘要： The invention relates to a fuel injection valve for the intermittent injection of fuel into the combustion chamber of an internal combustion engine having a housing which has a high pressure chamber and a low pressure chamber. In addition, the fuel injection valve has a control chamber which is divided by means of a control valve into a first and a second control chamber. The control valve in turn has a valve guide and a valve insert, wherein an outflow throttle which connects the first control chamber to the second control chamber is arranged in the valve guide. According to the invention, the connection which is formed by way of the outflow throttle between the first control chamber and the second control chamber can be interrupted temporarily in a targeted manner.
