摘要:
An electrohydraulic device, particularly an electric fuel pump for motor vehicle comprises a housing, a hydraulic connecting pipe and at least one electrical connecting plug for hydraulic medium and current supply respectively, a hydraulic conduit and a current cable extending to the housing, and a plug head. The hydraulic conduit and the current cable are connected with the plug head. The plug head is fitted over the connecting pipe and the connecting plug so as to establish hydraulic and electrical connection between the hydraulic conduit and the connecting pipe on the one hand and the current cable and the connecting pipe on the other hand.
摘要:
An internal tank/fuel pump unit has a vertically disposed, cylindrical unit housing 1 with an open lower end 3, into which a base plate 4 is inserted, which contains a suction channel 6, which goes out from the outer surface 5 of the base plate and terminates in a suction orifice 7 in the inner surface 8. In order largely to prevent the formation of gas bubbles, the outer surface 5 of the base plate 4 is smooth and terminates flush with the edge 9 of the unit housing 1.
摘要:
The invention relates to an apparatus for the degassing of fuel in a fuel supply system of an internal-combustion engine, in particular in a motor vehicle with a fuel tank, from which fuel is delivered to the fuel-feed system of the internal-combustion engine through a suction line and a pump and excess fuel is returned to the tank via a fuel return line. To achieve an effective and operationally reliable degassing, a vent in the form of a vent valve or a suction removal line with a jet pump is provided in the intake line at a geodetically highest point. Furthermore, reservoirs for separation of the gas bubbles may be connected into the intake line.
