Abstract: A fuel injector for fuel-injection systems of internal combustion engines which includes an elongated, axially running, thin-walled, non-magnetic sleeve. At its downstream end, the sleeve has a bottom section, which runs substantially normal to the otherwise axial extent of the sleeve along a longitudinal valve axis. A valve needle, which is securely joined to an armature and a valve-closure member, can move axially within a feed-through opening of the sleeve. The valve-closure member cooperates with a valve-seat surface provided on a valve-seat body, the valve-seat body being pressed into the sleeve and likewise abutting, for example, on the bottom section of the sleeve. The sleeve constituted as a drawn sheet-metal part extends axially over more than half of the axial length of the fuel injector. The fuel injector is suited for applications in fuel-injection systems of mixture-compressing internal combustion engines having externally supplied ignition.

Abstract: A fuel injection valve, in particular a high-pressure injection valve for the direct injection of fuel into the combustion chamber of a compressed mixture, externally ignited internal combustion engine, has in a guide and seat area provided at the downstream end of the valve which area is formed by three disk-shaped elements. A swirl element is nested between a guide element and a valve seat element. The guide element, which can move radially in the assembled valve and which has an inner guide opening, serves to guide an axially movable valve needle which extends through it, while a valve closing section of the valve needle acts in concert with a valve seat surface of the valve seat element. The guide element is spring-loaded through a compression spring which acts upon it.

Abstract: A fuel injection valve, in particular, a high-pressure injection valve, for injecting fuel directly into a combustion chamber of a compressed-mixture internal combustion engine with externally supplied ignition. The fuel injection valve includes a guide and seating area formed by three disc-shaped elements provided at the downstream end of the valve. A swirl element is embedded between a guide element and a valve seat element. The guide element is used to guide a valve needle which passes through it and can move in the axial direction, while a valve closing segment of the valve needle interacts with a valve seat surface of the valve seat element. The swirl element has an inner opening area with multiple swirl channels which are not joined to the outer circumference of the swirl element. The entire opening area extends completely across the axial thickness of the swirl element.
