    Abstract: A magnetic valve, in particular a fuel metering valve for fuel injection systems of internal combustion engines, is proposed which serves to measure the injection quantity and control the instant of injection. In a valve housing, the magnetic valve has an electromagnet and a valve closing element actuated thereby, which cooperates with a fixed valve seat. To damp the opening movement of the valve closing element against a fixed stop and to keep the hydraulic forces of adhesion between the valve closing element and the stop low, a damping chamber that is open toward the valve closing element is disposed on the stop. As the valve closing element approaches, fluid is positively displaced out of the damping chamber in the form of a squish flow between the stop face and the head element of the valve closing element, so that recoiling is avoided due to thus-generated damping. As the valve closing element lifts, fluid can flow through a throttle bore or a check valve into the damping chamber, so that release of the valve closing element from the stop face can be effected with little force being exerted.

    Abstract: The invention is directed to a method and apparatus for controlling the charger of an internal combustion engine as required by the operator of the vehicle. A first switch switches in the charger by energizing a relay when the accelerator pedal is depressed down to the end of the full-load position thereof. A second switch is connected in series with the first switch and interrupts the supply circuit for the relay thereby switching out the charger when the angular position of the throttle valve has dropped below a predetermined value. Self-holding contacts of the relay are connected in parallel with and bridge the first switch. In this way, the full-load curve without the charger switched in corresponds approximately to the curve defining engine operation with charger where switch-out of the charger is about to occur. In lieu of switching out the charger by releasing the accelerator pedal to a position corresponding to a predetermined constant angular position value of the throttle valve, this value at which switch-out occurs can be made dependent upon the rotational speed of the engine.

    Abstract: A rotary vacuum pump is proposed, having a rotor with vanes which rotates eccentrically within a housing bore. Each vane is coupled with a body which is ineffective at relatively low pump rpm; however, at higher rpm, the body engages the vane in such a manner that it removes the vane from its track within the housing bore.In this manner, an rpm-dependent shutoff device is created for the pump. In cooperation with the furnishing of underpressure as an auxiliary pressure in motor vehicles, the pump is used to supplement the underpressure which prevails when the internal combustion engine is at low, idling rpm; this prevailing underpressure is at a very low pressure level, and so when it is thus supplemented there is sufficient auxiliary vacuum force available over the entire rpm range.

    Abstract: In fuel delivery systems with two fuel pumps connected in series, two fuel distribution strips are provided in V-engines. Before now in this connection, there was the problem that in order to regulate the pressure in the two fuel distribution strips, a considerably high cost was required and/or the regulation of the pressure could not take place with the desired quality. In the fuel delivery system proposed here, a favorable pressure regulation in the two fuel distribution strips (21, 22) can be achieved by means of the one pressure control valve (30), with a minimum of rigid lines to be laid. The fuel delivery system is provided for an internal combustion engine of a vehicle.

    Abstract: A fuel delivery systems with first and second fuel pumps connected in series in which, a satisfactorily precise regulation of the fuel quantity supplied by the second fuel pump is possible. In particular, a switching time of a control valve that controls the fuel quantity is very short. The control valve includes an electromagnet which holds the valve member in a starting position. The electromagnet is supplied with just enough current that the valve member remains in this position. A slight change of the current supply of electromagnet can then cause the switching of the control valve into the end position within an extremely short period of time. The fuel delivery system is provided for an internal combustion engine of a vehicle.

    Abstract: An injection valve is described, in particular for direct injection of fuel into a combustion chamber of an internal combustion engine, with a valve body having a valve opening surrounded by a valve seat to form a spray opening, and with a valve needle which is pressed into its closed position, has a closing head and extends through the valve opening so that the closing head which works together with the valve seat is in contact with the valve seat on the spray side when the valve is closed. To ensure accurate fuel metering that is constant over a long period of time with such an injection valve, a plurality of fuel channels distributed around the periphery are arranged in the flow path upstream from the spray opening so that streams or strands of fuel coming out of the fuel channels are essentially maintained until downstream from the spray opening, and the individual cross sections of the fuel channels (29, 29', 29") together define a cross section of the flow path through the valve which determines the flow rate.
