摘要： Injecteur avec une configuration spécifique d'injection. Un premier ressort de fermeture (28) agit constamment sur l'aiguille (18) de soupape par l'intermédiaire d'un axe de pression central (34), et après exécution d'une course préliminaire (hv), un deuxième ressort (40) de fermeture agit au moyen d'un élément de pression (46). Celui-ci est supporté pendant une course préliminaire (hv) au moyen d'un manchon intermédiaire (48) sur le corps (10) d'injecteur. La course préliminaire (hv) est limitée par des épaulements (60, 62) sur l'aiguille de soupape (18) et par le manchon intermédiaire (48). Par contre, la course totale est limitée par des épaulements (64, 66) sur le manchon intermédiaire (48) et le disque intermédiaire (12). De cette manière, la course préliminaire (hv) peut être réglée de façon très précise à une valeur choisie en usinant l'aiguille (18) de soupape et ne change pas lors du montage de l'injecteur.
摘要翻译：具有特定注射配置的注射器。第一闭合弹簧（28）经由中心压力轴线（34）恒定地作用于阀针（18），并且在执行预备行程（hv）之后，第二弹簧（ 40）通过压力元件（46）起作用。这通过喷射器本体（10）上的中间套筒（48）在预行程（hv）期间被支撑。预行程（hv）由阀针（18）和中间套筒（48）上的肩部（60,62）限制。另一方面，总冲程由中间套筒（48）和中间盘（12）上的肩部（64,66）限制。这样，通过机加工阀针（18）可以非常精确地将预行程（hv）调节到选定值，并且在安装注射器时不会改变。

摘要： The invention relates to a fuel injection system for internal combustion engines. Said fuel injection system comprises a high-pressure accumulator chamber (15) that is impinged upon with highly pressurized fuel via a high-pressure conveyor unit (8) and that supplies the fuel injectors (19) with fuel. The high-pressure conveyor unit (8) is associated with a pressure regulating valve (12) that is disposed between a high-pressure side (10, 56) and a low-pressure side (11, 63) and comprises a valve element (54) which is actuated via an electric actuator (47). The pressure regulating valve (12) comprises a housing component (41) with a deformable zone (57) via which a gap L is adjusted between surfaces (48, 49) of an electrically actuated actuator unit (45, 47) when the pressure regulating valve (12) is assembled on a receiving body (52).

摘要： The invention relates to a fuel injection system for internal combustion engines, comprising a high-pressure accumulator compartment (15). Said high-pressure accumulator compartment (15) is impinged upon with highly pressurized fuel by a high-pressure feed unit (8) and supplies the fuel injectors (19, 23) with fuel. The fuel injection system comprises a pressure control valve (57) that is disposed between a high pressure side (33) and a low pressure side (50, 51, 52) and that actuates a valve element (47). The pressure control valve (57) is actuated by means of an electric actuator (46). The pressure control valve (57), with a front (53), delimits the low pressure zone (50, 51, 52) on the high-pressure accumulator compartment (15) and is sealed off by means of a low pressure seal (54).

摘要： The invention relates to a fuel injection valve for internal combustion engines, comprising a valve member (11) that can be displaced in the axial direction in a valve body (1). Said valve member cooperates with a valve seat surface (15) on the valve body (1) and with a tight surface (13) to control an injection orifice (17). The end of said member facing away from the combustion chamber is impinged upon by a valve spring (31) arranged in a spring chamber (29) in the closed position. The valve member (11) has a pressure shoulder (21) working in the opened direction, which projects into a pressure chamber (19) that can be filled with high pressure fuel. The spring chamber (19) is connected to the pressure chamber (19) through a choke gap and is closed in relation to a fuel return system so that the spring chamber (29) acts as a hydraulic damper when the valve member (11) lifts to the opened position.

摘要： To obtain a torsion-proof device of simple construction for the nozzle holder (26, 26a), including those of slim design, when clamped in the cylinder head of the engine, one component (50, 70) sits on a support (52, 72) formed by a recess (54, 74) on the periphery of the nozzle holder (26, 26a) to which it is secured preferably by resistance welding. To form a clamping shoulder for the engagement of a hollow screw (14) for tightening the injection nozzle, a slit pressure ring (42) sits on the union nut (24) and is provided in the region of the slit with recesses (62) for the component (50, 70). The preferred field of embodiment is injection nozzles for diesel engines.

摘要： Un dispositif simple conçu pour éviter le gauchissement du porte-injecteur (26, 26a) lorsque celui-ci est serré dans la culasse du moteur, même lorsque le porte-injecteur est du type mince, comprend un composant (50, 70) qui est calé dans un support (52, 72) formé par un évidement (54, 74) ménagé dans la circonférence du porte-injecteur (26, 26a), et qui est assujetti au support de préférence par soudage par résistance. Afin de former un épaulement de serrage destiné à l'engagement d'un boulon creux à filet femelle (14) qui serre l'injecteur, un cône de serrage à fente (42) est monté sur l'écrou d'accouplement (24) et est pourvu, dans la région de sa fente, d'évidements (62) pour le composant (50, 70). Les injecteurs pour moteurs diesel constituent le domaine préférentiel d'application de l'invention.
