    • An injector (10) has a single tapered valve (22) controlling fuel flow to a plurality of outlet passages (20). The entrance to each outlet passage has an orifice (42a,42b,42c,42d,42e,42f) surrounded by a raised valve seat (28a,28b,28c,28d,28e,28f). Each valve seat is separated from the other valve seats by a recessed space (38). The valve (22) pivots as it is displaced from the valve seats (28a,28b,28c,28d,28e,28f) to allow fuel flow through the outlet passages (20), and is constrained against other motion within the injector (10). The valve seats (28a,28b,28c,28d,28e,28f) are clustered beneath the free end of the valve (22). The orifices (42a,42b,42c,42d,42e,42f) are sized to compensate for the unequal lift of the tapered valve (22) from the valve seats (28a,28b,28c,28d,28e,28f).
    • 喷射器(10)具有控制到多个出口通道(20)的燃料流的单个锥形阀(22)。 每个出口通道的入口具有由升高的阀座(28a,28b,28c,28d,28e,28f)包围的孔口(42a,42b,42c,42d,42e,42f)。 每个阀座通过凹陷空间(38)与其它阀座分开。 当阀门(28a,28b,28c,28d,28e,28f)从阀座(28a,28b,28c,28d,28e,28f)移位时,阀(22)枢转,以允许燃料流过出口通道(20),并且被限制在喷射器 )。 阀座(28a,28b,28c,28d,28e,28f)聚集在阀(22)的自由端的下方。 孔口(42a,42b,42c,42d,42e,42f)的尺寸适于补偿锥形阀(22)与阀座(28a,28b,28c,28d,28e,28f)不相等的升力。

Each valve seat (28a,28b,28c,28d,28e,28f) is separated from the other valve seats by a recessed space (38). The valve (22) pivots about one end thereof as it is displaced from the valve seats to allow fuel flow through the outlet passages, and is constrained against other motion within the injector. The valve seats (28a,28b,28c,28d,28e,28f) are clustered beneath the opposite, free end of the valve (22). The orifices are sized to compensate for the unequal lift of the tapered valve (22) from the valve seats (28a,28b,28c,28d,28e,28f).
    • 喷射器(10)具有控制燃料流向多个出口通道(20)的单个锥形阀(22)。 每个出口通道的入口具有由凸起的阀座(28a,28b,28c,28d,28e,28f)围绕的孔口(42a,42b,42c,42d,42e,42f)。 每个阀座(28a,28b,28c,28d,28e,28f)通过凹入空间(38)与其他阀座分开。 当阀门从阀座移开时,阀门(22)围绕其一端枢转,以允许燃料流动通过出口通道,并且限制注射器内的其他运动。 阀座(28a,28b,28c,28d,28e,28f)聚集在阀(22)的相对的自由端下方。 孔的尺寸被确定为补偿锥形阀(22)从阀座(28a,28b,28c,28d,28e,28f)的不等升力。

    • Das Brennstoffeinspritzsystem weist die folgenden Merkmale auf;
      1: als Zumeßeinheit ist ein elektromagnetisch betätigtes Zumeßventil (15) vorgesehen;
      2: als Verteilereinheit ist ein synchron mit den Brennkraftmaschinenwellen laufender Drehschieber (28) vorgesehen;
      3: bei geöffnetem Zumeßventil (15) wird unter Druck stehender Brennstoff einmal über eine Spülleitung (9) in die Brennstoffrücklaufleitung (6) stromauf oder stromab des Brennstoffdruckreglers (8) und zum anderen in eine von zwei Volumenkammern (34, 35) beiderseits eines Freikolbens (36) geleitet, wobei die Verstellbewegung des Freikolbens (36) durch das Meßsystem (13) für den Istwert der eingespritzten Brennstoffmenge festgestellt wird.
