    摘要: A fuel inlet (36) opens at one end between the valve seat (14) and the inner surface of the valve housing (12) on which the globe valve (10) slides. The other end of the fuel inlet (36) opens to the external surface of the valve housing (12). The fuel inlet (36) runs almost in the direction of the central axis of the globe valve (10) so as to prevent the formation of vortex flow around the globe valve (10). Inside the valve housing (12) immedi. ately downstream of the valve seat (14) is fitted under pressure a spiral member (40) which is a rod with a spiral fuel groove (38) to swirl the fuel along the groove. Ano αtlet orifice (42) for fuel metering is formed immediately downstream of and as close as possible to the spiral member (40). In an other embodiment of the invention the valve housting (12) is surrounded by a housing (43) with fuel inlets (36'). This housing (43) is fightly connected to the downstream-end of the valve housing (12) having tangential bores (44) for assisting air-inlet joining with a conical space (45) and blowing the assisting air towards the axis of the outlet orifice (42).

    摘要: Es wird ein elektromagnetisch betätigbares Ventil vorgeschlagen, das insbesondere zur Kraftstoffeinspritzung in das Saugrohr von mit Kraftstoffeinspritzanlagen arbeitenden Brennkraftmaschinen dient. Das Kraftstoffeinspritzventil umfaßt ein Ventilgehaüse (1), einen Schalenkern (7) mit einer Magnetspule (18) und einen Flachanker (29), der mit einem kugelförmig ausgebildeten Ventilteil (30) fest verbunden ist, das eine zentrale Führungsöffnung (31) einer Führungsmembran (11) durchragt und mit einem festen Ventilsitz (32) zusammenwirkt. Die Führungsmembran (11) führt das Ventilteil (30) in radialer Richtung zum Ventilsitz (32). Der Flachanker (29) berührt unter Federspannung mit einer konzentrischen Führungskante (35) die Führungsmembran (11) und wird so planparallel zur Stirnfläche (28) des Schalenkerns (7) geführt. Die Kraftstoffzufuhr zum Ventil erfolgt durch radiale Zuströmöffnungen (68) in der Ventilwand. Der nicht zugemessene Kraftstoff kann nach Durchströmen des Magnetteiles über axial gegenüber den Zuflußöffnungen (68) versetzte und abgedichtete radiale Abflußöffnungen (70) in eine Kraftstoffrückströmleitung (67) gelangen.

    摘要: The invention relates to a fuel injection valve, especially a high pressure injection valve, for directly injecting fuel into a combustion chamber of a mixture-compressing, spark-injection internal combustion engine. Said fuel injection valve is characterised in that a valve seat element (26) is provided on the downstream end of the valve, a perforated disc (70) used as a flow limiting device being connected downstream from the same. A torsion element (47) is situated upstream of the valve seat (27), the fuel to be injected being displaced in a spray-stimulating rotational movement by means of said torsion element. A longish outlet (32) is embodied downstream from the valve seat (27), in the valve seat element (26), said outlet opening up directly into an opening (73) of the perforated disc (70) fixed to the valve seat element (26). The width of the outlet (32) is larger than the width of the opening (73), at least on the narrowest side thereof, in such a way that the static flow quantity of the valve can be adjusted at the opening (73).

    摘要: In a fuel injection valve body for a direct injection type internal combustion engine, an entire nozzle body tip portion (3a) is formed in a conical shape protruding from a nozzle body outer peripheral surface (3b) covered with a cap (24). Therefore, neither a corner portion nor a recessed portion is formed on a surface of the nozzle body tip portion (3a). This prevents heat generated by combustion from concentrating at a corner portion or a surface area or from enlarging by a recessed portion, which in turn prevents heat generated by combustion from increasing the temperature of the nozzle body tip portion (3a). Moreover, since a foremost portion (3c) of a spherical shape is formed such that it does not form a corner portion or a recessed portion in a peripheral portion of a conical shape, heat generated by combustion does not increase the temperature of the nozzle body tip portion (3a). The temperature of a nozzle hole can therefore be prevented from increasing and accumulation of deposits can be restricted.

    摘要翻译: 在直喷式内燃机的燃料喷射阀体中,整体喷嘴体前端部(3a)形成为从盖(24)覆盖的喷嘴体外周面(3b)突出的圆锥状。 因此,在喷嘴体前端部(3a)的表面上既不形成角部也不形成凹部。 这防止燃烧产生的热量集中在拐角部分或表面积处或由凹部扩大,这又防止燃烧产生的热量增加喷嘴体末端部分(3a)的温度。 此外,由于在圆锥形周边部不形成角部或凹部,因此形成球状的最前部(3c),所以燃烧产生的热量不会增加喷嘴体的温度 尖端部分(3a)。 因此可以防止喷嘴孔的温度升高,并且可以限制沉积物的积聚。
