A decoupling element for a fuel-injection device has a low-noise and pivotable construction. The fuel-injection device includes at least a fuel injector and a receiving bore in a cylinder head for the fuel injector as well as the decoupling element between a valve housing of the fuel injector and a wall of the receiving bore. The decoupling element is in the form of a ring, in particular a closed ring, which has a lower end face that sits on a shoulder of the receiving bore, and which has an upper end face that rises conically from radially outside toward radially inside and is in intimate contact with a spherically curved shoulder area of the valve housing of the fuel injector. The fuel-injection device is particularly suitable for the direct injection of fuel into a combustion chamber of a mixture-compressing combustion engine having externally supplied ignition.

Decoupling element for a fuel-injection device

A fuel-injection device has a low-noise and pivotable structure. The fuel-injection device includes at least a fuel injector and a receiving bore in a cylinder head for the fuel-injector, and a decoupling element between a valve housing of the fuel injector and a wall of the receiving bore. The decoupling element is captively situated on the fuel injector prior to its installation in the receiving bore in that a securing ring is mounted below the decoupling element at the outer periphery of the fuel injector and the securing ring is a closed plastic ring. The fuel-injection device is particularly suited for the direct injection of fuel into a combustion chamber of a mixture-compressing internal combustion engine having externally supplied ignition.

Fuel-injection device

A suspension mount for fuel-injection systems is used to connect a fuel injector to a fuel distributor. A connecting body having an accommodation space is provided, a fuel connector of the fuel injector being able to be disposed at least partially in the accommodation space. In addition, a joining body is provided that is disposed, at least in sections, partially in at least one recess of the connecting body, the recess being connected to the accommodation space, and on which the fuel connector is able to be supported along a longitudinal axis of the accommodation space. The joining body also has an elastically deformable element, the elastically deformable element being disposed in such a way that the joining body permits elastic support of the fuel connector on the connecting body at least along the longitudinal axis. A fuel-injection system having such a suspension mount is also indicated.

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.

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 is provided for fuel injection systems, the mounting connecting a fuel injection valve to a fuel-conducting component, and having a connecting body and a connecting piece that are connected to one another. Inside the connecting body and the connecting piece there is configured a receptacle space in which a fuel connector of the fuel injection valve is at least partly situated. An inner collar is configured on the connecting piece. In addition, an elastically deformable element is provided. The elastically deformable element is supported at least indirectly on the inner collar of the connecting piece. In addition, the fuel connector is supported at least indirectly on the elastically deformable element. In addition, a fuel injection system having such a mounting is described.

A connecting element connecting a fuel injection valve to a fuel-conducting component includes: a main body having a receptacle space into which a fuel connector of the fuel injection valve is introduced; and a fastening element. At least one opening is provided in a wall of the main body surrounding the receptacle space. The fastening element for fastening the fuel connector on the main body is brought into the receptacle space at least partly through the at least one opening. At least one elastic bearing element is provided, and the fastening element brought at least partly through the opening into the receptacle space is supported on the wall of the main body via the at least one elastic bearing element.

Fuel injection system having a fuel-conducting component, a fuel injection valve and a connection element

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 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.
