Abstract: The present invention relates to a distributor device (1) for fuel injection systems of internal combustion engines for supplying gas and for electrical contacting of fuel injection valves (2).The distributor device has a gas supply line (70) for the joint gas supply to the fuel injection valves (2), comprising a supply orifice (71) and a number of connecting parts (7) for connecting the supply orifice (71) to gas inlet channels (13) of the fuel injection valves (2). Furthermore, a plurality of bushings (78) are provided along the gas supply line (70) and work together with plugs (47) provided on the fuel injection valves (2) to establish electric contact with the fuel injection valves (2).In the refinement according to this invention, a locking spring (88) is provided for each bushing (78) to lock the connection of the bushing (78) to the plug (47) of the respective fuel injection valve (2).

Abstract: Known pressure regulator valves for motor vehicles are comprised of a relatively large number of individual parts that have to be assembled at a high cost. In the pressure regulator valve set forth, the stop piece and the housing part are injection molded. This reduces assembly costs in the manufacture of the pressure regulator valve. The pressure regulator valve is particularly suited for fuel delivery systems of motor vehicles with an internal combustion engine.

Abstract: A fuel injection system includes a substantial integration of various components, the fuel injection system including at least one fuel injector and at least one intake manifold, as well as a fuel supply channel, which are all surrounded by a plastic sheathing. The full integration of the fuel injectors into an induction pipe component made of plastic leads to the reduction or elimination of both electrical and hydraulic interfaces. Thus, only a compact component remains that is very simple to attach to a cylinder head of an internal combustion engine. Means for electrically contacting the fuel injectors (1), such as connector sockets, are also fully integrated in the plastic sheathing. This fuel injection system is especially suited for use in mixture-compressing internal combustion engines having externally supplied ignition.

Abstract: The invention joins the intake module or intake tube to the engine with the aid of a displaceable retaining element. The retaining element, which in the mounted state is under initial tension, is braced against an engine retention face associated with the engine and against at least one counterpart intake module retention face joined to the intake module or intake tube. Because of the displaceability of the retaining element, the expense and effort of mounting and dismantling the intake module or intake tube to the engine by screws are substantially reduced. The engine is intended in particular for motor vehicles.

Abstract: A contact strip which includes a contact strip housing and a support part, which has conductor channels with connection leads extending within the conductor channels. Projecting from the contact strip are electrical connection leads in a lead line which serve to contact the fuel injection valves and which are fitted with plug elements, which contact electrical conductors of the fuel injection valves. The contact strip has an advantage of providing a contact to several fuel injection valves, which may be of any kind of construction, in a simple and reliable manner. The contact strip is particularly suitable for making common electrical contact to electrically operated fuel injection valves of internal combustion engines.

Abstract: A fuel distributor for supplying fuel to a plurality of fuel injection valves of the top feed type, in which the inlet and the return necks are disposed on one end of the fuel distributor, so that mounting of the fuel distributor is simplified and the space required is reduced. A connection cap having a return neck is disposed on the distributor housing, and a central pressure regulator is disposed on its face end on a second end. The pressure regulator and the return neck of the connection cap communicate with one another through a central return line extending within the distributor housing. The fuel distributor is especially suitable for fuel injection systems of mixture-compressing internal combustion engines externally supplied with ignition, for supplying fuel to a plurality of fuel injection valves.
