The present invention relates to a valve of a fuel injector for selectively disconnecting a high pressure region from a low pressure region of a fuel, comprising an opening in a seat plate, an armature which is designed to close the opening of the seat plate, a spring element which prestresses the armature in the direction of a position which closes the opening, and an electromagnet for lifting the armature out of the position which closes the opening into a position which releases the opening, characterized by an elastically compressible damping element for limiting an armature stroke in the case of the armature being lifted from the seat plate into the releasing position.

Valve of a fuel injector

The invention relates to a connecting piece for a fuel injector of an internal combustion engine comprising at least one high-pressure input port and at least one high-pressure output port, wherein the high-pressure input port and the high-pressure output port open into an internal high-pressure accumulator of the connecting piece and/or the injector via separate high-pressure feed channels.

Connecting piece for a fuel injector of an internal combustion engine

A fuel injector having a seat plate with a passage throttle; a valve insert arranged at a first side of the seat plate; a valve guide surrounding the valve insert and adapted for slidable reception of the valve insert; a spring sheath surrounding at least a section of a jet needle arranged at a second side of the valve insert, the second side opposite the first side and the seat plate; a valve chamber fluidly connected to the passage throttle; a control chamber adapted for reception of fuel; and a line arranged in the valve insert connecting the control chamber and the valve chamber to one another, wherein the line is closeable by placement of the valve insert onto the spring sheath.

Injector for injecting fuel

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.
