Abstract
A fuel injector (1) for the direct injection of fuel, especially into the combustion chamber of a mixture-compressing internal combustion engine having external ignition, is located in a cylinder head (2) of the internal combustion engine in a receiving bore (8) of the cylinder head (2), and includes a nozzle body (10) and a sealing ring (14) which seals the fuel injector (1) from the cylinder head (2) of the internal combustion engine. At an end (12) on the discharge side of the fuel injector (1), an at least partially spherical body (13) is formed which abuts at least partially against a wall (9) of the receiving bore (8), a groove (15) being circumferentially formed on the body (13) in which the sealing ring (14) is positioned.

A fuel injector (1) for the direct injection of fuel, especially into the combustion chamber of a mixture-compressing internal combustion engine having external ignition, the fuel injector being positioned in a cylinder head (2) of the internal combustion engine in a receiving bore (8) of the cylinder head (2), and comprising a nozzle body (10) and a sealing ring (14) which seals the fuel injector (1) from the cylinder head (2) of the internal combustion engine, wherein, at a downstream side of end (12) of the fuel injector (1), an at least partially spherical body (13) is formed which at least partially abuts against a wall (9) of the receiving bore (8), at the body (13) a receptacle (15) being circumferentially formed in which the sealing ring (14) is placed.
A fuel injector (1) for the direct injection of fuel, especially into the combustion chamber of a mixture-compressing internal combustion engine having external ignition, the fuel injector being located in a cylinder head (2) of the internal combustion engine, in a receiving bore (8) of the cylinder head (2), and having a nozzle body (10) and a sealing ring (14) which seals the fuel injector (1) from the cylinder head (2) of the internal combustion engine,
- wherein a spring (25) is clamped between a fuel-distributor line (4) and the fuel injector (1) and enables the fuel injector (1) to be elastically aligned in its position relative to a connecting piece (26) of the fuel-distributor line (4).
