摘要： A fuel injection system is proposed which brings about an improvement in the acceleration behavior of an internal combustion engine. The fuel injection system includes metering valves actuatable by means of an air flow measuring device, at which valves a pressure difference can be held constant via control valves and the pressure difference is variable in accordance with operational characteristics of the engine. To this end, the control valves are located on a control pressure line in which a control throttle and an electromagnetic valve are disposed. At the same time, pressure limitation elements communicate with the control pressure line and, in the event of acceleration of the engine, reduce the extent of increase of control pressure and thus assure fuel metering corresponding with the operational state of the engine.

摘要： A fuel injection system is proposed which brings about an improvement in the acceleration behavior of an internal combustion engine. The fuel injection system includes an intake manifold having a measuring device arranged therein which is moved against a restoring force in accordance with the quantity of air flowing therethrough and thereby actuates the control slide of a distribution valve. The restoring force on the air flow measuring device is actuated by fuel, supplied by a fuel pump via a damping throttle, which operates within a pressure chamber into which the control slide protrudes by means of an end face. A check valve is arranged in a discharge line between the pressure chamber and the delivery side or the suction side of the pump, and opens above a predetermined pressure within the pressure chamber. This allows a rapid unloading of the pressure chamber and a rapid response of the fuel injection system in the case of an acceleration.

摘要： A fuel injection system is proposed which serves to adapt the fuel-air mixture as precisely as possible to operating conditions of the internal combustion engine. The fuel injection system includes metering valves, each of which is assigned a regulating valve whose movable valve element can be exposed on one side to the fuel pressure downstream of the respective metering valve and on the other side to a control pressure line defined on one end by a control pressure valve of the nozzle/impact plate type and on the other end by a control throttle. The control pressure valve has a permanent magnet and an electromagnet, the magnetic fluxes of which are guided via an armature in such a manner that in at least one air gap the magnetic fluxes of the permanent magnet and of the electromagnet extend in the same direction, while in at least one other air gap the magnetic fluxes of the permanent magnet and of the electromagnet extend in opposite directions. This kind of embodiment requires a substantially smaller triggering power on the part of the electromagnet. By reversing the exciter current of the electromagnet, the control pressure valve is opened widely enough that the control pressure engaging the regulating valves causes the closure of the regulating valves, and the injection of fuel is precluded.

摘要： A regulating apparatus is proposed for a fuel supply system for a mixture-compressing, externally ignited internal combustion engine, which serves to enrich the fuel-air mixture furnished to the engine when it is started cold and while it warms up. The regulating apparatus comprises a pressure-regulating valve which sets the fuel pressure, the closing force of which on the movable valve part is influenced by a temperature-dependent element by means of a relay device and a regulating spring coaxially correlated therewith. Accordingly in a predetermined temperature range, the temperature-dependent element and the movable valve part are connected only by the regulating spring.

摘要： Known tank flanges have a main filter which has a filter housing with an inlet and an outlet, and a first connecting duct for connecting the main filter to a feed unit. The filter housing is integrated in the tank flange, and filter fabric is inserted into the filter housing and the filter housing is closed off by a filter cover. The inlet of the filter housing is connected to the pressure side of a feed unit and the outlet leads to an internal combustion engine. A disadvantage is that, in order to exchange the filter fabric, the large-area filter cover must be opened, as a result of which a large amount of fuel vapor is dissipated to the atmosphere. In the case of the tank flange according to the invention, the exchangeability of the main filter is simplified by virtue of the main filter being embodied as a filter cartridge. It is provided according to the invention that the inlet of the main filter extends into the first connecting duct of the tank flange and therein forms a sealed connection.

摘要： A devices for pumping fuel has at least one suction jet pump and a drive line, supplying the suction jet pump with fuel, that branches off from a pressure line leading to an internal combustion engine and that can be blocked off by means of a shutoff valve. By means of a shutoff valve, it is possible to switch off the suction jet pumps. The pressure of the pressure line acts on the shutoff valve in such a way that the shutoff valve closes at a pressure that is greater than or equal to a predetermined closing pressure.
