Abstract:
A pump device for high pressure fuel delivery in fuel injection systems of internal combustion engines comprising a common rail injection system, a pump housing (2) in which high pressure is exerted on fuel by a number of pump elements, the fuel that is acted on with high pressure is delivered to a common high pressure connecting bore (8) by means of a high pressure conduit system, the high pressure conduit system includes a number of high pressure conduits (6, 7) in the housing, which communicates with the pump elements and are disposed in a plane different from that of the common high pressure connecting bore (8) in which the high pressure conduits (6, 7) come together, in which the pump housing is provided with blind bores (3, 4, 5) communicating with the pump elements and the high pressure conduits (6 and 7) pass through the blind bores (3, 4, 5) in an off-center fashion.
