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.

Abstract: The control valve of the invention has two inlets and one outlet, where a first inlet and the outlet are provided at the front side and the second inlet at the circumference of the control valve. The inlets end in a valve chamber having a fluid connection to the outlet via a valve seat opening. The valve seat opening has a valve seat that can be closed with a valve body that is moveably arranged in a control valve. The outlet extends into the valve chamber with a valve seat section. A radial gap is provided between the valve seat section and a peripheral wall of the valve chamber. The control valve is suitable to be retrofitted to a reservoir pan in order to secure the fuel supply of a single-stage delivery assembly in each operational state when a two-stage delivery assembly is replaced by a single-stage delivery assembly. The control valve comprises a separate valve housing, which is designed such that it can be inserted and fastened in a cylindrical opening.
