摘要： An improved r.p.m. regulator of a fuel injection pump for internal combustion engines includes an improved control spring mechanism. The control spring mechanism is connected to one end of a control lever which in turn is connected at its other end to a fuel supply quantity setting member. The control lever serves to actuate the fuel supply quantity setting member in accordance with the forces applied to the control lever by the control spring mechanism and an r.p.m.-dependent force applying structure which applies a force to the control lever in opposition to the force applied by the control spring mechanism. The control spring mechanism in one embodiment of the invention includes axially aligned tandem springs mounted between the control lever and a setting lever, a first connecting member and a second connecting member. In another embodiment of the invention a single spring is mounted between the control lever and a setting lever and tandem springs are mounted adjacent to one end of the second connecting member in a perforated pot that is associated with the control lever.

摘要： A fuel injection pump is proposed, which has a centrifugal governor disposed in the suction chamber of the fuel injection pump, the governor having a sleeve displaceable on a piston, and a pressure chamber enclosed in the interior of the governor sleeve, the latter being defined by the end face of the piston. By means of a relief line of the pressure chamber which is opened in the offset position of the governor sleeve, the restoring force on the centrifugal governor is increased during starting by the amount of the pressure difference appearing at the governor sleeve. Beyond a predetermined adjustment of the governor sleeve, the relief line is blocked, so that the governor can function unhindered within the normal operational range. The hysteresis thus resulting upon the shut-off of the increased starting quantity improves the behavior of the engine as it runs up to operational speed.
摘要翻译：提出了一种燃料喷射泵，其具有设置在燃料喷射泵的吸入室中的离心调节器，调节器具有可在活塞上移位的套筒和封闭在调节器套筒内部的压力室，后者被限定通过活塞的端面。通过在调速器套筒的偏移位置打开的压力室的释放线，在启动期间，离心调速器上的恢复力增加了出现在调速器套筒上的压力差。除了调速器套筒的预定调整之外，泄压线被阻挡，使得调速器可以在正常工作范围内无阻碍地工作。因此，由于关闭增加的启动量而导致的滞后改善了发动机运行到运行速度的行为。

摘要： A fuel injection pump for Diesel engines in which a rotating and reciprocating piston pressurizes and distributes fuel to individual pressure lines leading to the injection valves of the engine. In order to change the timing of injection with respect to the engine cycle, there is provided a mechanism to change the relative angle between the pressurizing piston and its drive means, which runs in synchronism with the engine. The mechanism operates hydraulically and is affected by the fuel pressure in the sump of the injection pump. There is also provided a hydraulic control valve mechanism which permits varying amounts of fuel to flow back from the sump to the low pressure side of the fuel delivery pump, thereby changing the injection timing. A primary control valve adjusts the sump pressure on the basis of engine speed while a secondary control valve adjusts the sump pressure on the basis of engine temperature in order to adapt the timing of fuel injection to engine starting and engine warm-up. Various embodiments are presented.

摘要： The invention relates to a fuel injection pump for internal combustion engines having an injection onset adjuster with which the injection onset is adjustable toward "early", for instance in accordance with temperature. In accordance with the invention this adjustment toward "early" is made possible especially in pumps having a load-dependent injection onset adjustment, which preferably exhibit a shift toward "late" up to full load.
