본 발명은 청구항 1의 전제부에 따른 연료 펌프 제어 장치에 관한 것이다.The present invention relates to a fuel pump control device according to the preamble of claim 1.

하나의 캠에 배속된 제어 곡선의 운동을 진동 레버를 통해 내연기관의 분사 펌프의 펌프 태핏으로 전달하는, 실제로 공지된 연료 펌프 제어 장치에서는 펌프 태핏을 제어하기 위한 힘의 흐름 또는 힘의 도입(force flow or force entray)이 진동 레버에 배속된 롤러 바디가 상기 캠 상에서 롤링하도록 이루어지며, 상기 롤링 운동으로 인해 상기 진동 레버가 그것의 회전축을 중심으로 선회되고, 상기 진동 레버의 롤러 바디 측면 옆에 배치된, 상대 회전 불가능한 측벽은 진동 레버의 선회 운동을 펌프 태핏에 배속된 태핏 롤러 바디 상으로 전달함으로써, 결국 제어할 펌프 태핏과 상호 작용하는 태핏 롤러 바디의 진동하는 또는 단계적인 운동이 야기된다. 제어할 펌프 태핏으로의 이러한 힘 도입은 전체 장치가 현저한 기계적 부하를 받기 때문에 쉽게 마모된다는 단점을 갖는다.In a really known fuel pump control device, which transfers the movement of a control curve assigned to one cam to a pump tappet of an injection pump of an internal combustion engine via a vibration lever, the force flow or force for controlling the pump tappet A roller or body in which a flow or force entray is assigned to the vibration lever is rolled on the cam, and the rolling movement causes the vibration lever to pivot about its axis of rotation and is located next to the roller body side of the vibration lever. The non-rotatable sidewalls, in turn, transfer the pivoting movement of the vibrating lever onto the tappet roller body attached to the pump tappet, resulting in a vibrating or stepwise movement of the tappet roller body interacting with the pump tappet to be controlled. This introduction of force into the pump tappet to be controlled has the disadvantage that it wears easily because the whole device is subjected to significant mechanical loads.

본 발명의 과제는 상기 단점을 갖지 않는 연료 펌프 제어 장치를 제공하는 것이다. An object of the present invention is to provide a fuel pump control device which does not have the above disadvantages.

상기 과제는 청구항 1에 따른 연료 펌프 제어 장치에 의해 해결된다. 본 발명에 따라 상기 또는 각각의 펌프 태핏의 태핏 롤러 바디가 대응하는 진동 레버의 롤러 바디 상에서 직접 롤링한다.The problem is solved by the fuel pump control device according to claim 1. According to the invention the tappet roller body of the or each pump tappet rolls directly on the roller body of the corresponding vibration lever.

본 발명에서, 제어할 펌프 태핏을 작동시키는 태핏 롤러 바디는 대응하는 진동 레버의 롤러 상에서 직접 롤링한다. 이는 펌프 태핏 내로의 개선된 힘 도입 또는 최적의 힘 흐름을 결과한다. 본 발명에 따른 연료 펌프 제어 장치는 적은 기계적 부하를 받기 때문에, 적게 마모된다.In the present invention, the tappet roller body operating the pump tappet to be controlled rolls directly on the roller of the corresponding vibration lever. This results in improved force introduction or optimal force flow into the pump tappet. The fuel pump control device according to the invention is less worn because it is subjected to less mechanical load.

본 발명의 바람직한 실시예는 종속 청구항 및 하기 설명에 제시된다. 본 발 명의 실시예가 첨부된 도면을 참고로 상세히 설명되지만, 본 발명이 이에 국한되는 것은 아니다.Preferred embodiments of the invention are set forth in the dependent claims and the description below. Embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited thereto.

이하, 본 발명을 도 1 및 도 2를 참고로 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to FIGS. 1 and 2.

도 1은 내연기관, 특히 커먼 레일 디젤 내연기관의 고압 연료 공급을 위한 내연기관의 분사 펌프의 펌프 태핏(11)을 제어하기 위한 본 발명에 따른 장치(10)를 도시한다. 제어할 펌프 태핏(11)은 가이드(12)에 지지되고 종방향 중심축의 방향으로 이동 가능하다. 펌프 태핏(11)의 가이드(12)에는 연료 펌프의 연결을 위한 소위 어댑터(14)가 고정된다.1 shows an apparatus 10 according to the invention for controlling a pump tappet 11 of an injection pump of an internal combustion engine for the high pressure fuel supply of an internal combustion engine, in particular a common rail diesel internal combustion engine. The pump tappet 11 to be controlled is supported by the guide 12 and movable in the direction of the longitudinal central axis. In the guide 12 of the pump tappet 11 a so-called adapter 14 for the connection of the fuel pump is fixed.

펌프 태핏(11)을 제어하기 위한 본 발명에 따른 장치(10)는 도 1에 따라 제어 곡선(23)을 가진 하나 이상의 캠(15)을 포함한다. 상기 캠(15)은 도시된 실시예에서 소위 3중 캠으로서 구현된다. 진동 레버(16)에 배속된 롤러 바디(17)가 캠(15) 또는 그것의 제어 곡선(23) 상에서 롤링한다. 롤러 바디(17)는 진동 레버(16)의 한 단부(18)에 회전 가능하게 지지되고, 진동 레버(16)는 상기 단부(18)에 대향하는 단부(19)의 회전점(20)을 중심으로 선회 가능하다.The device 10 according to the invention for controlling the pump tappet 11 comprises at least one cam 15 with a control curve 23 according to FIG. 1. The cam 15 is embodied as a so-called triple cam in the embodiment shown. The roller body 17 attached to the vibration lever 16 rolls on the cam 15 or its control curve 23. The roller body 17 is rotatably supported at one end 18 of the vibration lever 16, with the vibration lever 16 centering on the point of rotation 20 of the end 19 opposite the end 18. You can turn to.

태핏 롤러 바디(21)는 제어할 펌프 태핏(11)과 상호 작용하고, 펌프 태핏(11)에 의해 규정된(defined) 챔버(22) 내에 배치되고 상기 챔버 내에 회전 가능하게 지지된다. 본 발명에서, 태핏 롤러 바디(21)는 진동 레버(16)의 롤러 바디(17) 상에서 직접 롤링하므로, 태핏 롤러 바디(21)는 진동 레버(16)의 롤러 바디(17) 상에서 연속적으로 롤링한다. 따라서, 펌프 태핏(11)을 제어하기 위한 힘은 캠(15)으로부터 진동 레버(16)의 롤러 바디(17) 내로, 그리고 상기 롤러 바디(17)로부터 직접 태핏 롤러 바디(21) 내로 도입되고, 상기 태핏 롤러 바디(21)가 결국 펌프 태핏(11)을 작동시킨다. 캠(15)으로부터 롤러 바디(17)를 통해 태핏 롤러 바디(21)로의 직접적인 힘의 도입으로 인해, 소위 접촉 수직력의 바람직한 방향 각도가 주어진다. 본 발명에 따른 장치는 적게 마모되며 적은 마찰 손실을 갖는다.The tappet roller body 21 interacts with the pump tappet 11 to be controlled and is disposed in the chamber 22 defined by the pump tappet 11 and rotatably supported in the chamber. In the present invention, the tappet roller body 21 rolls directly on the roller body 17 of the vibration lever 16, so that the tappet roller body 21 continuously rolls on the roller body 17 of the vibration lever 16. . Thus, the force for controlling the pump tappet 11 is introduced from the cam 15 into the roller body 17 of the vibration lever 16 and directly from the roller body 17 into the tappet roller body 21, The tappet roller body 21 eventually activates the pump tappet 11. Due to the introduction of the direct force from the cam 15 through the roller body 17 into the tappet roller body 21, the preferred directional angle of the so-called contact vertical force is given. The device according to the invention wears less and has less frictional losses.

본 발명에 따른 장치는 단일 캠 시스템에 그리고 다중 캠 시스템에 그리고 내연기관의 고압 연료 공급을 위한 모든 방식의 피스톤 펌프에 사용될 수 있다.The apparatus according to the invention can be used in single cam systems and in multiple cam systems and in piston pumps of all manner for high pressure fuel supply of internal combustion engines.

본 발명에 따라 상기 또는 각각의 펌프 태핏의 태핏 롤러 바디가 대응하는 진동 레버의 롤러 바디 상에서 직접 롤링한다.According to the invention the tappet roller body of the or each pump tappet rolls directly on the roller body of the corresponding vibration lever.
