Abstract

Disclosed is a fuel conveying device including a valve housing in which a pressure release valve and a non-return valve are arranged parallel to one another, the pressure release valve having a first inlet, which downstream of a valve seat opens into a valve chamber in which a valve body is movably arranged and which is in fluid connection with a second inlet for the non-return valve via a first outlet. The device improves the control response of the pressure release valve by providing the first outlet at the periphery of the valve chamber and in the axial direction with respect to a valve axis such that when the pressure release valve is open the flow from the valve chamber into the second inlet is a substantially radial flow.
