摘要： A mechanical injection-pump governor with an electronically controlled torque-control in which, as a function of parameters, a stepping motor controllable by an electronic control device adjusts with its actuator a full-load stop interacting with the quantity-adjustment member of the injection pump. The torque-control movement of the actuator is limited by an end stop situated a short distance above the maximum full-load control path and by an end stop situated a short distance below the minimum full-load control path.

摘要： A mechanical injection pump governor is provided having a first adapting device which acts in the lower speed range up to the full-load characteristic curve of a supercharged diesel engine for adapting the delivery quantity of the injection pump to the fuel requirement of the diesel engine. The adapting device contains a spring-loaded diaphragm which is acted upon by a supercharge and is connected to the control rod of the injection pump. The lift of the diaphragm, when supercharge pressure is applied, is limited by a full load stop which determines the adapting end point. To improve the torque profile of the diesel engine, a second adapting device is provided which adjusts the full load stop. By means of this second adapting device, the full load stop can be displaced against an additional spring force when supercharge pressure is progressively applied so that the delivery quantity of the injection pump increases between the adapting end point and the rated speed of the diesel engine.

摘要翻译： 一种机械式注射泵调速器，其具有第一适配装置，该第一适配装置作用于增压柴油发动机的最低速度范围直到满载特性曲线，以使喷射泵的输送量适应柴油发动机的燃料需求。 适应装置包含弹簧加载的隔膜，其通过增压作用并连接到注射泵的控制杆。 当施加增压压力时，隔膜的升力受到满载停止的限制，该满载停止决定了适应终点。 为了改善柴油发动机的扭矩分布，提供了调整满载停止的第二适配装置。 通过该第二适配装置，当逐渐施加增压压力时，全负载停止可以抵抗额外的弹簧力移动，使得喷射泵的输送量在柴油发动机的适应终点和额定转速之间增加。

摘要： An injection nozzle has an insert with helical swirl channels functioning as a single-jet nozzle for air-compression fuel-injection internal combustion engines, with a nozzle needle opening inwards. To achieve fuel atomization constant in terms of engine speed and load in all the operating ranges of the internal combustion engine and having a relatively invariable mushroom-like atomization form on the nozzle outlet side, the nozzle needle can be moved free of stops in the opening direction over the entire operating range, counter to the force of a spring, as a function of the fuel pressure prevailing in the pressure space, in such a way that when there is an equilibrium between the spring force and the force exerted on the needle in the pressure space, an almost always equal pressure ratio independent of the engine speed and arising in the valve-seat region is established, together with a constant outflow speed free to the combustion space.

摘要： A fuel injection pump for internal combustion engines with the injection pump including a dual-acting check valve arranged between the pump cylinder and a valve holder of the injection pump. The check valve is constituted by a resilient valve disk which includes a central passage. A base plate, provided with inlet bores and a central throttle acting in a direction opposite a fuel conveying direction of the injection pump, is arranged between the pump cylinder and the valve holder. The base plate forms an abutment for the valve disk when the check valve opens in a direction opposite the fuel conveying direction of the injection pump.
