ABSTRACT:
An injector for injecting fuel into the combustion chamber of an internal combustion engine includes an injector housing, in which a pressure chamber surrounds an insert part. The pressure chamber can be filled with fuel at high pressure via a high-pressure inlet. Via the pressure chamber, a control chamber defined by the insert part and a valve component is subjected to pressure. The valve component is movable inside the insert part, thus executing a stroke motion. A one-piece, metal sealing element is received by a nonpositive connection on the circumference of the insert part is subjected to the high pressure prevailing in the pressure chamber.
