A connecting element for fuel injection systems is used for connecting a fuel injector to a fuel-carrying component, in particular a fuel distributor rail. A base body having a receiving space is provided for this purpose. The base body has an opening, via which a fuel fitting of the fuel injector is insertable into the receiving space of the base body. Furthermore, a first annular element is provided in the receiving space, which in the installed state on the one hand interacts with the fuel fitting inserted into the receiving space and on the other hand interacts with the base body. Furthermore, a second annular element is provided in the receiving space of the base body, the first annular element and the second annular element abutting against an outside of the fuel fitting in the installed state.

A connecting element for fuel injection systems is used for connecting a fuel injector to a fuel-carrying component. For this purpose, the connecting element has a base body, which is connected on the one side in a form-locking manner to the fuel-carrying component and on the other side is connected in a form-locking manner to the fuel injector. The base body is developed as a bracket-shaped base body, the base body having a first arm, a second arm and a connecting web. The base body abuts on a first contact surface, which is provided on the first arm, on the one side against the fuel-carrying component and on a second contact surface, which is provided on the second arm, on the other side against the fuel injector. An elastic decoupling is provided between the first contact surface and the second contact surface. Furthermore, a fuel injection system having a fuel-carrying component, a fuel injector and such a connecting element is indicated.

A connecting element for fuel injection systems is used for connecting a fuel injector to a fuel-carrying component. A connecting part is provided, which is fastened on the one side on a shoulder of the fuel-carrying component and, on the other side, on a shoulder of the fuel injector. For this purpose, the connecting part is developed at least partially as a pot spring. A fuel injection system having such a connecting element is also indicated.

A mounting device for attaching a fuel injector both to a cylinder head of an internal combustion engine and to a fuel distribution line, includes two spring tongues which are insertable into a holding groove of the fuel injector or the fuel distribution line. A distance between the tips of the spring tongues is smaller than the largest diameter of the opening surface enclosed by them, and the spring tongues are radially elastically displaced with respect to an axis of the fuel injector. At least two spring elements, elastically displaced in the axial direction with respect to the spring tongues by either tensile or compressive forces, are formed and are axially non-positively, detachably connectable to the opposite fuel injector or the fuel distribution line via a catch connection.

A fuel injector, e.g., for fuel-injection systems of internal combustion engines in motor vehicles, includes a valve housing including a sleeve-shaped housing section; and a solenoid, situated on the housing section, having a coil brace, magnetic coil and magnetic cup. To protect the magnetic coil from salt fog that arises under specific environmental conditions and penetrates along the contact areas of solenoid and housing section, the coil brace with wound magnetic coil is completely enclosed on all sides by a one-piece plastic coat.

A fuel injector, in particular a fuel injector for fuel-injection systems of internal combustion engines, includes a valve needle cooperating with a valve-seat surface to form a sealing seat, and has an armature engaging with the valve needle, the armature being axially moveable on the valve needle and damped by a damping element made of an elastomer. The damping element is positioned in a recess of the armature at the valve needle in such a way that the valve needle is connected to the armature in the radial direction via the damping element.

A connecting device for fuel injection systems is used for connecting a fuel injection valve to a fuel-carrying component. A wire-shaped connecting element is provided in this context, which is fastened, on the one hand, to the fuel-carrying component and, on the other hand, to the fuel injection valve. The wire-shaped connecting element is embodied closed in an annular manner, and, on the one hand, is guided about a shoulder of the fuel-carrying component and, on the other hand, about a shoulder of the fuel injection valve. A fuel injection system having such a connecting device is also provided.

A suspension for fuel injection systems is used for connecting a fuel injector to a fuel-carrying component. A connecting body having a receiving space is provided for this purpose. The connecting body has an opening, via which a fuel fitting of the fuel injector is insertible at least partially into the receiving space of the connecting body. Furthermore, an annular element and an elastically deformable element are provided. Fuel fitting is supported via the annular element and the elastically deformable element along an axis of the receiving space of the connecting body. A fuel injection system having such a suspension is also indicated. The suspension allows for a soft coupling of the fuel injector to the fuel-carrying component at a desired target stiffness.
