    • 본 발명은 내연기관의 연소실 내로 연료를 분사하기 위한 분사 밸브(1)에 관한 것이다. 상기 분사 밸브(1)의 노즐 니들(17)은 분사 단면의 개방 및 폐쇄를 위해 샤프트(19)에 의해 종방향으로 이동되도록 하우징 내에서 가이드된다. 상기 노즐 니들(17)은 노즐 니들에 작용하는 연료 압력 및 상기 노즐 니들의 폐쇄 방향으로 작용하는 폐쇄 스프링(16)에 의해 작동된다. 상기 폐쇄 스프링(16)은 노즐 니들(17)의 지지부와 하우징 사이에서 초기 압축 응력을 받고 노즐 니들 가이드(26)와 밸브 시이트(18) 사이의 영역에서 노즐 니들의 주변에 배치된다. 이와 같은 배치의 장점은 분사 밸브(1)의 치밀한 구조 및 노즐 니들 후면에 놓인 제어실(11)의 낮은 불감 부피이다.
    • 用于将燃料喷射到内燃机的燃烧室中的喷射阀具有在壳体内被引导的喷射器针头,使得喷射器针可以通过轴纵向移动以打开和关闭喷射横截面。 喷射器针由作用在喷射器针上的燃料压力和通过沿着注射针的关闭方向作用的闭合弹簧致动。 闭合弹簧在喷射器针头和壳体上的支座之间被预压缩,并且位于喷射器针头的周边上喷射器针头导向器和阀座之间的区域中。 该装置的一个优点是喷射阀的紧凑结构和在喷射器针的背面上的控制室的低死体积。

    • The invention relates to a fuel injector for internal combustion engines, which comprises an axial bore (8) which can be cross-flown by fuel in the nozzle body (7), said bore receiving a nozzle needle (6) which is guided in an axially displaceable manner in the nozzle body (7). Said nozzle needle (6) comprises a seating surface in the nozzle head on one end thereof, and supports a bushing (1) which can be displaced in relation to the nozzle needle (6) and which is arranged on the periphery of the nozzle needle (6), on the other end thereof. Said bushing (1) defines a control chamber (10) which is connected to the chamber which is circulated by fuel on the external side of the bushing (1) via an inlet channel (2, 9) in the bushing (1) and which is supported in an elastic manner on the nozzle needle (6), in a position counter to an axial component of the fuel injector which is connected to the nozzle head (7), and comprises an outlet channel which is controlled by a control valve. According to the invention, a filter (3) for filtering the fuel which flows over the inlet channel (2, 9) to the control chamber is provided on the bushing (1).
    • 本发明涉及一种用于内燃机的燃料喷射器,其包括可在喷嘴体(7)中由燃料交叉飞行的轴向孔(8),所述孔容纳喷嘴针(6),该喷嘴针 在喷嘴体(7)中可轴向移动。 所述喷嘴针(6)在其一端包括喷嘴头中的安置表面,并且支撑可相对于喷嘴针(6)移位并且布置在喷嘴针的周边上的衬套(1) (6),其另一端。 所述衬套(1)限定了一个控制室(10),该控制腔室(10)通过衬套(1)中的入口通道(2,9)连接到腔室,该腔室通过衬套(1)的外侧上的燃料循环, 在喷嘴针(6)上以与喷嘴头(7)连接的燃料喷射器的轴向分量相对的位置以弹性方式支撑,并且包括由控制阀控制的出口通道。 根据本发明,用于将在入口通道(2,9)上流过控制室的燃料过滤的过滤器(3)设置在衬套(1)上。

    • The invention relates to a fuel injection device comprising a fuel pump embodied as a double piston pump which is used to pump fuel into the combustion chamber of an internal combustion engine to an injector respectively associated therewith and which is optimized with regard to the injection process thereof. The double piston pump comprises two pistons (70, 73) which pump in parallel along a common line and which are provided with control edges. A control rod (71,74) is associated with each piston (70,73) and is used to control the beginning and end of the pumping. The beginning of the pumping can be adjusted on the first piston (70) and the end of the pumping can be adjusted on the second piston (73). A control pressure is provided prior to the beginning of injection according to engine operation parameters in order to adjust the force acting upon the injector needle (12) in the direction of closure, said pressure enabling pressure to be impinged upon the valve needle (12) in the direction of closure. In order to compensate an alteration in the beginning of injection caused thereby, the control rod (71) of the first piston (70) regulating the beginning of pumping is adjusted accordingly.
    • 本发明涉及一种燃料喷射装置,其包括实施为双活塞泵的燃料泵,所述双重活塞泵用于将燃料泵入内燃机的燃烧室至分别与其相关联的喷射器,并且针对其喷射过程进行了优化 。 双活塞泵包括两个活塞(70,73),它们沿共同的管线平行泵送并设置有控制边缘。 控制杆(71,74)与每个活塞(70,73)相关联,并用于控制泵送的开始和结束。 可以在第一活塞(70)上调节泵送的开始,并且可以在第二活塞(73)上调节泵送的端部。 在注射开始之前根据发动机操作参数提供控制压力,以便调节在关闭方向上作用在喷射器针头(12)上的力,所述压力使得压力能够撞击在阀针(12)上, 在关闭的方向。 为了补偿由此引起的注射开始的变化,相应地调节调节泵送开始的第一活塞(70)的控制杆(71)。
