Application 10/089,668
unit time through the fuel injector depends on a position of the adjusting
body in the sleeve (claim 26; Figure 2, 3, and 4). Appellant indicates that
including the adjusting body (40) permits flow rate of the fuel to be adjusted
in a mechanical manner (Specification 3: 15-18).
Claims 26, 28, and 29 are illustrative:
26. A fuel injector for a fuel injection system of an internal
combustion engine, in particular for direct injection of fuel into a
combustion chamber of the engine, the fuel injector comprising:
an actuator;
a valve closing body to form a sealing seat with a valve seat face;
a valve needle mechanically linked to the actuator and to be acted
upon by a restoring spring in a closing direction, to actuate valve closing
body;
a sleeve to pre-stress the restoring spring; and
an adjusting body placed in direct contact with the sleeve so as to be
adjustable so that a fuel amount flowing per unit of time through the fuel
injector depends on a position of the adjusting body in the sleeve.
28. The fuel injector of claim 26, wherein the restoring spring is
supported on an injection end of the sleeve.
29. The fuel injector of claim 27, wherein the position of the adjusting
body is variable in the sleeve via a first adjusting tool.
