Nozzle Assembly and Fuel Injection Valve for a Combustion Engine
First Claim
1. A nozzle assembly for a fuel injection valve for a combustion engine, the nozzle assembly comprising:
- a valve body with a central longitudinal axis;
a valve cavity within the valve body; and
a nozzle tip body comprising a protrusion limiting a free volume of the valve cavity;
wherein the protrusion extends from an end surface of the nozzle tip body in an extending direction parallel to a longitudinal axis of the nozzle tip body away from the valve cavity; and
the protrusion comprises a first section adjacent to the end surface, the first section having a cylindrical outer surface, and a second section adjacent to the first section, the second section having an outer surface of decreasing diameter in the course away from the end surface along the extending direction; and
at least one nozzle aperture out from the valve cavity through the protrusion.

Abstract
The present disclosure generally relates to nozzles for a valve and, more specifically, to a fuel injection valve for a combustion engine. In some embodiments, a nozzle assembly for a fuel injection valve for a combustion engine may include: a valve body with a central longitudinal axis; a valve cavity within the valve body; a nozzle tip body comprising a protrusion limiting a free volume of the valve cavity; and at least one nozzle aperture out from the valve cavity through the protrusion. The protrusion may extend from an end surface of the nozzle tip body in an extending direction parallel to a longitudinal axis of the nozzle tip body away from the valve cavity and comprise a first section adjacent to the end surface, the first section having a cylindrical outer surface, and a second section adjacent to the first section, the second section having an outer surface of decreasing diameter in the course away from the end surface along the extending direction.
