摘要:
A high-pressure fuel system for internal combustion engines, having a housing that contains two high-pressure bodies. The high-pressure bodies rest with contact surfaces at least indirectly against each other and are pressed against each other by means of a tensioning device. A supply conduit is embodied in the high-pressure bodies, which carries highly pressurized fuel and passes through the contact surfaces of the two high-pressure bodies. A sealing film is disposed between the two high-pressure bodies, which encompasses the passage of the high-pressure conduit and thus assures a favorable seal.

The invention relates to a method for producing a high-pressure fuel reservoir for a common rail fuel injection system of an internal combustion engine, having a hollow base body (1) which is equipped with a plurality of connection openings (3). In a simple method that can be performed inexpensively, a connection bore (4) is predrilled. The communication between the connection bore (4) and the interior (2) of the base body (1) is created with the aid of a further machining method.

An arrangement for forwarding fuel from a fuel tank to an internal combustion engine includes a fuel-forwarding device having a suction side and an elevated pressure side. An inlet conduit connects the suction side with the fuel tank, while a fuel-forwarding conduit forwards the fuel from the elevated pressure side. A fuel filter housing for accommodating a fuel filter surrounds the fuel-forwarding device. The fuel filter housing is connected with the fuel-forwarding device in an electrically conductive manner. One of the fuel filter housing and the fuel-forwarding device is connected to a location that is at a predetermined electrical potential.

In connection with an arrangement for fastening a corrugated pipe (11) on an essentially hollow-cylindrical connector (12), at least one spring leg (15), which extends at a radial distance from and in a longitudinal direction to the connector (11) and has a retaining lug (18) radially projecting toward the latter, is formed on the connector (12), and an annularly-shaped clamping element (20) is placed on the outside around the corrugated pipe (11) pushed onto the connector (12), which generates a radial clamping force directed toward the corrugated pipe (11) on the at least one spring leg (15), for providing a dependable and simple connection technique (FIG. 2).
摘要:
To guard against electrostatic discharge in a pressure regulator, a flange of a fuel delivery module for connecting a tank with a fuel feed line of an engine, having a pressure regulator for regulating the pressure in the fuel feed line, and having at least one hookup for an external electrical potential, is characterized in that the flange is embodied in at least some portions of weakly electrically conductive material, in such a way that the hookup is connected conductively with the pressure regulator via the weakly electrically conductive material.
摘要:
A delivery device for fuel to an internal combustion engine, which includes a fuel reservoir. After the engine is shut off or in the event of an accident, there is the danger that the pressurized fuel present in the fuel reservoir will escape from the delivery device. A blocking device is provided on the fuel reservoir, which after the engine is shut off or after an accident, the blocking device engages with an actuation rod that is provided with detent teeth, by means of an electromagnetically actuated locking pin and thus prevents a force impingement of a compression spring on the movable wall of the fuel reservoir. By use of the blocking devices the pressure in the fuel line is completely reduced even after the escape of small fuel quantities. The delivery device is suited for mixture-compressing internal combustion engines with externally supplied ignition.

A feeding device for fuel having an electric motor, a feed pump which is driven by the electric motor, a filter arranged in a fuel stream of the feed pump, a housing accommodating the electric motor, the feed pump and the filter, a fuel tank for a fuel supply and provided with a tank flange which forms a cover, tubular connections for guiding a fuel stream in a feeding direction and to the tank flange, the tubular connections being composed of an electrically conductive plastic and producing a throughgoing electrical ground connection of all components through which a fuel flows.
摘要:
A device for receiving a fuel delivery unit (12) inside a fuel tank, in particular of motor vehicles, is proposed. The fuel delivery device (12) is essentially completely surrounded by a damping element (14), wherein the damping element (14) is connected with a holding device (13) and essentially completely decouples the fuel delivery unit (12) from the holding device (13). The device (11) can be arranged via the holding device (13) in the fuel tank. (FIG. 1 in connection with this).
摘要:
An arrangement for supplying fuel to an internal combustion engine of a motor vehicle has a supply tank, an aggregate which is located in the supply tank and a fuel delivery unit for supplying fuel from the supply tank to the internal combustion engine. The aggregate has a plurality of components extending along a delivery path of the fuel, is located in the supply tank, and is provided with a supporting element which carries a holding member for the components of the aggregate.
