A fuel supply device for internal combustion engines wherein the temperature of the fuel fed to an injection pump can be regulated in order to avoid temperature influences on the fuel metering operation. For this purpose, fuel is withdrawn in a controlled quantity via a temperature-controlled valve from the intake chamber of the injection pump, where the fuel is under the feed pressure of a fuel feed pump and the withdrawn fuel is fed, either by way of a heat exhchanger or directly back to the intake side of the fuel feed pump. In this arrangement, the inherent fuel heating process taking place in the fuel injection pump is exploited to regulate the temperature of the fuel fed to the fuel feed pump. |
