Abstract: 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.

Abstract: 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.

Abstract: The present disclosure relates to a nozzle for a fuel injector that comprises a pivotably symmetrical nozzle member having a hollow space for introducing a nozzle needle, a nozzle tip that is provided at a longitudinal end of the nozzle member, and at least one opening for discharging fuel, and a nozzle needle arranged in the hollow space for a selective blocking of a fuel inflow to the at least one opening, wherein the nozzle needle is designed as tubular in the region of the nozzle tip and is adapted to conduct fuel in the interior of the tubular region to the at least one opening.

Abstract: The present invention relates to a sealing sleeve for the separated supply and discharge of a cooling medium that comprises a sealing member that is pivotally symmetrical about the longitudinal axis, a protrusion projecting radially outwardly with respect to the longitudinal axis at the upper longitudinal end of the sleeve member, a protrusion projecting radially outwardly with respect to the longitudinal axis at the lower longitudinal end of the sleeve member, a first web section and a second web section of which each one extends in the axial direction of the sleeve member and connects the upper protrusion to the lower protrusion, and a first wall region and a second wall region of which each one is bounded in the axial direction by the upper and lower protrusions and in the peripheral direction by the first and second web sections and is radially inward offset with respect to these elements, with the upper protrusion and the lower protrusion each extending continuously around the total periphery of the slee

Abstract: 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.

Abstract: 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.
