Patent ID: 8066030

Claim:
In a fuel conveying device equipped with a valve housing in which a pressure relief valve and a check valve are situated in parallel with each other; wherein the pressure relief valve has a first inlet that, downstream of a valve seat, opens into a valve chamber in which a valve member is movably arranged and which, via a first outlet, is flow connected to a second inlet for the check valve, wherein the first outlet is provided at a periphery of the valve chamber and is arranged in an axial direction with respect to a valve axis such that when the pressure relief valve is open, an essentially radial outflow occurs from the valve chamber into the second inlet, wherein the pressure relief valve and the check valve are arranged offset from each other in the axial direction so that the first outlet of the pressure relief valve feeds into the second inlet of the check valve in the radial direction, and the first outlet of the pressure relief valve is situated close to its valve seat in the axial direction with respect to the valve axis in such a way that no axial flow around the pressure relief valve member occurs when the pressure relief valve is open, wherein the check valve is located within a pressure line through which fuel is conveyed from a point within the pressure line that is upstream of said check valve to a point within the pressure line that is downstream of said check valve, and wherein the pressure relief valve receives fuel from a point within the pressure line that is downstream of said check valve and allows it to flow back to a point within the pressure line that is upstream of said check valve.
