摘要： 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.
摘要翻译：提出一种电磁阀，特别是用于内燃机燃料喷射系统的燃料计量阀，其用于测量喷射量并控制喷射时间。在阀壳体中，电磁阀具有由其驱动的电磁体和阀关闭元件，其与固定阀座配合。为了将阀关闭元件的打开运动阻挡在固定止动件上，并且保持阀关闭元件和止挡件之间的液压力的粘合力低，在止动件上设置朝向阀关闭元件开口的阻尼室。当阀关闭元件接近时，流体在止动面和阀关闭元件的头元件之间以挤压流的形式被正确地移出阻尼室外，从而避免由于这样产生的阻尼而的反冲。当阀关闭元件提升时，流体可以流过节流孔或止回阀进入阻尼室，从而可以以很小的力施加阀关闭元件从止挡面的释放。

摘要： In a vane type compressor, in which a plurality of radial vanes are supported on a compressor shaft and extended through a rotary piston, each vane is formed of two wall portions spaced from each other and two ring portions receiving bearings for supporting the vanes on the shaft. The wall portions and the ring portions of each vane are formed as a one-piece element which may be produced by stamping-out and bending a sheet metal. A supporting structure of kernels of aluminum disposed in a honeycomb manner is inserted between two wall portions of each vane.

摘要： 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.
摘要翻译：本发明涉及一种用于根据车辆操作者的要求控制内燃机的充电器的方法和装置。当加速器踏板向下压到其全负载位置的末端时，第一开关通过给继电器通电来切换充电器。第二开关与第一开关串联连接，中断继电器的供电电路，当节流阀的角位置降低到预定值以下时，将充电器切断。继电器的自保持触点与第一开关并联连接。以这种方式，没有充电器开关的满载曲线大致对应于即将发生充电器开关的充电器定义发动机运转的曲线。通过将加速器踏板释放到对应于节流阀的预定的恒定角度位置值的位置来代替切断充电器，可以根据发动机的转速来进行切换的值。

摘要： 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.
摘要翻译：提出了一种旋转式真空泵，其具有带有在壳体孔内偏心旋转的叶片的转子。每个叶片与在相对较低的泵转速下无效的主体联接; 然而，在更高的转速下，主体以这样的方式接合叶片，使得它从壳体孔内的轨道上移除叶片。以这种方式，为泵创建一个依赖于rpm的切断装置。在提供负压作为汽车辅助压力的同时，泵用于补充内燃机处于低空转时的负压; 这种普遍的负压处于非常低的压力水平，因此当其被补充时，在整个rpm范围内存在足够的辅助真空力。

The fuel supply system is provided for an internal combustion engine of a vehicle.

摘要： 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.

摘要： 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.
