摘要： A fuel supply device, which serves to predetermine a fuel quantity that is proportional to the aspirated air quantity, and also serves to spread the air-fuel mixture. The fuel supply device includes an air metering device, which is arranged in the air intake manifold of the internal combustion engine and activates a fuel metering device, which has a control slit that opens a control groove by a varying amount. The control slit and the control groove are rotatable relative to each other, and the control groove has at least one control edge, which overlaps the control slit and is formed at an angle relative to the axis of rotation. The control slit is arranged in a guide sleeve and the control groove is arranged in a rotatable sleeve mounted in the guide sleeve with the rotatable sleeve being arbitrarily shifted relative to the guide sleeve. A connecting tube is arranged between the rotatable sleeve and the mounting axis of the air metering device, by means of which the metered fuel can be fed to a nozzle arranged on the air flow rate meter. For a better mixture spreading effect, air can be fed to the metered fuel through a filter composed of a fine-meshed web.

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 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.

摘要： A pressure control valve for a fuel injection system is proposed which serves to control the warm-up fuel quantity for a mixture-compressing, externally ignited internal combustion engine. The pressure control valve includes a movable valve part which is urged in the closing direction by a compression spring which is counteracted during the warm-up phase by a first temperature-dependent element, whose force on the compression spring below a predetermined temperature in the direction of an increase in the force of the first temperature-dependent element can be influenced by a second temperature-dependent element, so that the fuel-air mixture during the warm-up phase can be adapted to the requirements of every internal combustion engine.

摘要： A supplementary air valve controlling a supplementary air quantity during the warm-up phase of an internal combustion engine. The supplementary valve is arranged in a lateral channel which bypasses the throttle valve and has a flat vane provided with a flow-through aperture; the vane is pivotable about a shaft eccentrically situated with respect to the flow-through aperture by means of a bimetallic spring provided with an electric heating coil energized through the engine ignition switch and which rotates the vane to uncover the cross-sectional areas of two spaced-apart, coaxially arranged air supply tubes which together form a part of the lateral channel and the vane has at least one further flow-through aperture for opening the cross-sectional area of a pressure control line which when closed, permits the induction tube pressure downstream of the throttle valve to prevail in the air control line, and when opened, the induction tube pressure upstream of the throttle valve prevails in the air control line.
