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 decoupling element, for decoupling a fuel injection valve from a cylinder head, includes a body that, in the mounted state, surrounds a housing of the fuel injection valve. The body is fashioned to include a cylinder-side support region to be supported on the cylinder head, and a valve-side support region for supporting the fuel injection valve. When the fuel injection valve is supported at the valve-side support region, the body is loaded with pressure. Only the cylinder-side support region of the body is fashioned in the shape of a closed ring, which connects segments of the body distributed around a circumference. The decoupling element enables the reduction of the transmission of noise from the fuel injection valve to the cylinder head.

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 solenoid valve for controlling fluids includes a closing element that opens and closes at least one outlet opening on a valve seat, and a magnetic circuit that includes an armature, an internal pole, a magnetic return path, and a coil, the armature being connected to the closing element. The magnetic circuit includes a nonmagnetic separating element for interrupting the magnetic circuit and at least one magnetic crosspiece running in a direction of a longitudinal extension of the valve and situated on the nonmagnetic separating element.

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.

A valve for metering fluid is reported which has a valve housing having a valve opening and a valve seat, a valve needle, which is provided for the alternating closing and opening of the valve using a closing member cooperating with the valve seat, a resetting element that acts on the valve needle for closing the valve and an electromagnet that is able to have current applied to it, having a magnet armature that is drivable to a lift motion, which sits axially displaceably on the valve needle and carries along the valve needle in the lift direction for opening the valve via a driving flange situated on it. To simplify production and the assembly of the valve while achieving the advantages characteristic in valves having a prestroke spring and an armature free path, the magnet armature is supported on the valve housing using a diaphragm spring.

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.

In an adjusting device having a gear, high gear ratios are often demanded. High transverse forces often arise in the gear and must be intercepted by suitably dimensioned bearings. In the adjusting device proposed here, having a basic body and a cap, an embedded device is provided between a shaft, serving to support a gear wheel, and the cap. With the aid of the embedded device, good bearing of the gear wheel on both sides is attained, regardless of component tolerances. The adjusting device is intended especially for vehicles having an internal combustion engine.

A throttle device for controlling an internal combustion engine, in which the throttle valve is supported precisely employs a bearing recess serving to support the throttle valve shaft which is surrounded by a clamping element. As a result, there is excellent, durable stabilization of the bearing recess. The throttle device is especially well suited to vehicles that have a throttle-type internal combustion engine.

In an adjusting device with a transmission, high gear ratios are frequently required. In the transmission, powerful lateral forces are frequently generated, which must be absorbed by correspondingly dimensioned bearings. The present invention proposes an adjusting device having a transmission in which at least one gear is supported on an axle with a diameter that varies in the longitudinal direction. This achieves a uniform material loading of the axle supporting the gear and permits the diameter of the axle as a whole to be significantly reduced. The adjusting device is particularly intended for motor vehicles with an internal combustion engine.
