본 고안은 연료분사장치의 일원이 인젝션 펌프의 연료 분사시기를 조정하는 자동차의 인젝션 펌프 타이머구조에 관한 것이다.The present invention relates to an injection pump timer structure of a vehicle in which a member of a fuel injection device adjusts a fuel injection timing of an injection pump.

종래에는 인젝션 펌프에 타이밍을 개선하도록 서브(Serve)타이머를 구성하였으나 서브타이머는 가공상 상당히 어려움이 있으며 타이머의 동적 히스테리시스가 많은 등으로 타이밍이 불안정한 문제점이 있었다.Conventionally, the sub-timer is configured to improve the timing of the injection pump, but the sub-timer has a considerable difficulty in processing, and the timing is unstable due to the dynamic hysteresis of the timer.

본 고안은 상기에서와 같은 종래의 문제점을 해결하기 위하여 안출된 것으로, 타이밍 피스톤에 중공실을 형성하고 유압판을 탄력 설치하여 타이머의 개선을 가져올 수 있도록 한 것이다.The present invention is devised to solve the conventional problems as described above, to form a hollow chamber in the timing piston and to install the hydraulic plate elasticity to bring the improvement of the timer.

이한 첨부된 도면에 의하여 본 고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1, 2도에서와 같이 하우징(1)의 하부에 타이밍 피스톤(2)을 스프링(3)으로 탄설한 인젝션펌프(P)에 있어서, 상기 타이밍 피스톤(2)의 한측에 중공실(21)을 형성하고 유압판(4)을 스프링(5)으로 탄력 설치한 것이다.In the injection pump P in which the timing piston 2 is mounted with the spring 3 under the housing 1 as shown in FIGS. 1 and 2, the hollow chamber 21 is located on one side of the timing piston 2. To form and to elastically install the hydraulic plate 4 with the spring (5).

이와 같이 구성된 본 고안은 타이밍 피스톤(2)에 유압이 가해질 때 중공실(21)에 탄설된 유압판(4)에 일부 압력이 가해져 유압판(4)이 중공실(21)내에 탄력적으로 입출 하면서 유압을 조정하여 분사시기를 효과적으로 조정하게 되는 것이다.The present invention configured as described above has a partial pressure applied to the hydraulic plate 4 installed in the hollow chamber 21 when the hydraulic pressure is applied to the timing piston 2 while the hydraulic plate 4 elastically enters and exits in the hollow chamber 21. By adjusting the hydraulic pressure, the injection timing is effectively adjusted.

본 고안은 상기한 작용에 의해 타이머의 동적 히스테리시스를 줄일 수 있고 스피드나 토크에 따른 타이밍의 안정성을 도모하는 효과가 있으며, 특히 기존의 인젝션 펌프에 용이하게 구성할 수 있는 이점이 있다.The present invention can reduce the dynamic hysteresis of the timer by the above-described action, has the effect of promoting the stability of the timing according to the speed or torque, in particular, there is an advantage that can be easily configured in the conventional injection pump.
