摘要： An electromagnetically operated valve wherein a spherical valve member normally engages one of two seats to thereby connect a port for spent fluid with a port which is connected with a consumer of pressurized fluid. The valve member is held in such position by the plunger of an armature which is accommodated in a fluid-filled chamber provided in the valve housing and communicating with a fluid-admitting port. When the winding of the electromagnet is energized, the plunger is retracted to permit movement of the valve member into engagement with the other seat whereby the port which is connected to the consumer communicates with the fluid-admitting port. The plunger can be held in a position in which the valve member engages the one seat by fluid pressure in the chamber and/or by a spring.

摘要： A method of operating a multiple-electromagnet arrangement (eg for a fuel-injection valve) is proposed in which, to shift the armature(s) from one position to another, exclusively switch-off operations of the electromagnet(s) are used. In a device for implementing the method, circuit elements (106, 105; Figs. 6; 7) are provided which produce a current-fall time shorter than the current-rise time of the electromagnets. With a single armature (17, Fig. 1) between two electromagnets (11, 12) - both are switched on, then one is switched off to move the armature towards the other. With two coupled armatures (59, 66; Fig. 4), each between a respective pair of electromagnets (53,54 and 60,61), the energising sequence of Fig. 5 (top two traces) is used to produce reciprocation of the armature (bottom trace).

摘要： A fuel injection system (1) for internal combustion engines comprises a fuel injection valve (7), which injects fuel into a combustion chamber (6), defined by a cylinder wall (2), in which a piston (3) runs and a spark plug, extending into the combustion chamber (6). Said fuel injection valve (7) is arranged such that a conical injection stream (13) is produced in the combustion chamber (6). In the vicinity of the spark plug (8) the conical injection stream (13) thus comprises an angular section (17).

EN EL ENTREHIERRO COMPRENDIDO ENTRE LAS DOS ZAPATAS POLARES (10, 11) DE UN ELECTROIMAN (12) SE HA DISPUESTO UN IMAN PERMANENTE (17). FRENTE AL IMAN PERMANENTE (17) SE ENCUENTRA UN INDUCIDO (18), QUE PUEDE MOVERSE LIBREMENTE EN EL ENTRE-HIERRO EXTERNO (19). EL IMAN PERMANENTE (17) REFUERZA EL EFECTO CINETICO EJERCIDO POR EL INDUCIDO (18), UNA VEZ QUE HAYA SIDO CONECTADO EL ELECTROIMAN (12). DURANTE EL PROCESO DE DESCONEXION DEL ELECTROIMAN (12) EL CAMPO MAGNETICO (23) DEL IMAN PERMANENTE (17) ACELERA LA DESAPARICION DEL CAMPO MAGNETICO Y, POR LO TANTO, TAMBIEN LA REDUCCION DEL EFECTO CINETICO SOBRE EL INDUCIDO (18). EL DISPOSITIVO ELECTROMAGNETICO DE CONEXION ES ESPECIALMENTE ADECUADO PARA SU EMPLEO EN VALVULAS DE INYECCION DE COMBUSTIBLE PARA MOTORES DE COMBUSTION INTERNA.

摘要： A fuel injection system for internal combustion engines with multiple fuel injection valves. The fuel injection system includes a dimensionally stable fuel manifold distributor with nipple plug connections, by means of which the fuel is directed to the individual injection valves. The fuel manifold distributor is disposed over the injection valves and is pitched with respect to the horizontal, with a fuel injection connection located at the lowest point of said manifold and connected to the pressure side of a fuel pump, with a return line connection provided at the highest point of the fuel manifold distributor leading to a return flow line, over which a portion of the fuel may be redirected to a pressure regulator and from there to the suction side of a fuel tank to which the fuel pump is connected. The fuel manifold distributor design described here makes it possible for the vapor lock bubbles that are formed to enter the return flow line after the hot internal combustion engine has been switched off, and to be directed to the suction side of the fuel pump when said internal combustion engine is restarted, thus making it possible to avoid problems in starting.

摘要： The pump is located in a common housing with an electric drive motor and has individual pump elements (rollers) in grooves of a driven rotor disc, which engage on a roller track, located eccentrically to it. An intermediate plate (10) has a radial suction slot (17), which extends over a given circumferential area, and forms a passage. The slot permits radial inlet of the fuel to be delivered. Preferably the intermediate and base plate (7) are at a distance from the surrounding housing wall (2). They are held on a support plate (9), which seals the suction side (14) from the pressure side (15), and abuts a sealed housing shoulder.
