Abstract
The invention relates to a pump device for high pressure fuel delivery in fuel injection systems of internal combustion engines including a pump housing. The pump housing includes a number of pump elements, in which high pressure is exerted on fuel. The fuel that is acted on with high pressure is delivered by the individual pump elements to a common high pressure connecting bore by use of a high pressure conduit system. In order to reduce stress in the bores the high pressure conduit system includes a number of high pressure conduits which communicate with the pump elements and are disposed in a plane different from that of the common high pressure connecting bore in which the high pressure conduits come together at the connecting bore. Through the disposition of the common high pressure connecting bore in a plane different from that of the high pressure conduits, the high pressure conduits can intersect with the high pressure connecting bore in an eccentric fashion.
