摘要： In a magnetic valve serving to block a fuel inlet line (10) to supply a pump working chamber of a fuel injection pump with fuel, the closing component (28) has a drilling (50) penetrating from the front which can be closed off by a valve member (61) under the action of a closing spring (57). On the occurrence of pressure surges in the intake line section (31) closed off by the closing member (28) and leading to the pump working chamber, the closing member (28) and the entire cross-section of the intake line section (31) is not opened but only the cross-section of the drilling (50). This drilling is quickly closed again by the low-mass valve member (61) after the surge has passed so that only small quantities of fuel can flow via the drilling (50) to equalise the pressure.

摘要： The invention concerns a security arrangement in which a cap-shaped element (34) is mounted over essential setting and/or operating elements (11, 25) of a fuel-delivery system. The cap-shaped element (34) is connected to parts of the fuel-delivery system surrounded thereby such that access or removal of the cap-shaped element (34) is possible only using destructive means. When a given destructive force has been exceeded, a fracture occurs at a predetermined breaking point (52), which destroys a setting or operating element (25) or the wall (26, 27) supporting the latter and delimiting fuel-delivering chambers in the fuel-delivery system.

摘要： The proposal is for a protective device which prevents the unauthorised access to an adjusting or operational component of a fuel supply device, especially a fuel injection pump. The protective device consists of a basic component with a base via which it is screwed to a housing wall of the fuel supply system and a cover (44) which encloses the functional component (25) on the basic component (34) in such a way that the cover has a side wall which is further positively surrounded by a side wall (36) of the basic component. Thus access to the functional component (25) and the securing system of the basic component (34) is prevented. The cover (44) is secured to the basic component by safeguarded fixing means (54).

摘要： Pompe à injection de carburant à distributeur, présentant un régulateur de vitesse mécanique, pour lequel un levier de tension (28) et un levier de démarrage (29) formant un ensemble de leviers de réglage, coopèrent de telle façon qu'ils fonctionnent, au-delà d'un régime de ralenti, en système compound, dans lequel l'organe de commande du débit (13) est relié au levier de démarrage, cependant qu'il est prévu en outre un ressort de ralenti (31) associé à ce levier de démarrage, ledit ressort présentant, conformément à l'invention, une précontrainte capable d'être modifiée en fonction des caractéristiques de fonctionnement, de manière à obtenir une variation correspondante de la quantité débitée en régime de ralenti, par exemple, en cas de surcharge en ralenti (mise en circuit d'un groupe d'appareils, moteur encore froid).

摘要： Une électrovanne servant à la coupure d'une conduite d'aspiration de carburant (10) pour l'alimentation en carburant d'un espace de travail d'une pompe d'injection de carburant, présente sur la partie de fermeture (28) un trou (50) entrant par le devant et pouvant être obturé au moyen d'un élément de soupape (61) sous l'effet d'un ressort de fermeture (57). En présence d'à-coups de pression dans le tronçon de la conduite d'aspiration (31) obturée par la partie de fermeture (28) et menant vers l'espace de travail de la pompe, la partie de fermeture (28) et toute la section de la partie de la conduite d'aspiration (31) ne s'ouvrent pas, mais uniquement la section du trou (50). Ce trou, après avoir été ouvert, est rapidement refermé par l'élément de soupape (61) à faible masse, de façon que seulement de faibles quantités de carburant puissent passer à travers le trou (50) en vue de l'égalisation de pression.

摘要： The invention concerns a distributor fuel-injection pump for internal combustion engines, with a mechanical rpm controller in which a tensioning lever (28) and a starting lever (29) operate together as a control lever system in such a way that, above the idle rpm value they act as a compound system, the volume control element (13) being connected to the start lever and, in addition, the starting lever being acted on by an idler spring (31), the tension in which can be changed as a function of operating parameters in order to give a corresponding change in the quantity delivered when idling, for example in the event of an idling overload (caused by switching in electrically powered auxiliaries or when cold-starting).
