Abstract
The present invention relates to a valve of a fuel injector for selectively disconnecting a high pressure region from a low pressure region of a fuel, comprising an opening in a seat plate, an armature which is designed to close the opening of the seat plate, a spring element which prestresses the armature in the direction of a position which closes the opening, and an electromagnet for lifting the armature out of the position which closes the opening into a position which releases the opening, characterized by an elastically compressible damping element for limiting an armature stroke in the case of the armature being lifted from the seat plate into the releasing position.
Claims20
A valve (1) of a fuel injector for a selective separation of a high pressure region from a low pressure region of a fuel comprising:
- an opening (2) in a seat plate (3);
- an armature (4) that is configured to close the opening (2) of the seat plate (3);
- a spring element (5) that preloads the armature (4) in the direction of a position closing the opening (2);
- and
- an electromagnet (6) for raising the armature (4) from the position closing the opening (2) into a position releasing the opening (2), wherein
- an elastically compressible damping element (7) to bound an armature stroke on the raising of the armature (4) from the seat plate (3) into the releasing position.
