    • A fuel injection pump for internal combustion engines which has a supply volume adjusting mechanism, being adjustable via a starting lever, an adjusting lever, and a tensioning lever. The starting lever is supported on the tensioning lever via a starting spring, and at non-operation of the engine, the starting spring is supported on a lever stop. To set the optimum amount of fuel to be injected at starting of the engine, which must be reduced at hot start, as opposed to a cold start, the lever stop is forcibly coupled with the adjusting lever such that the lever stop is moved by a swivel movement of the adjusting lever from a first end position to a second end position with the end positions being arranged so that the lever stop forces a starting lever position which in the first end position sets an amount of fuel on the supply volume adjusting mechanism as required for the hot start, and in the second end position, the lever stop sets an amount of fuel as required for the cold start.

    • In a fuel injection pump for internal combustion engines for motor vehicles, a damping device is provided to eliminate so-called vehicle bucking. The device allows rapid adjusting movements of an rpm adjusting lever, which is connected to the driving lever, to affect the supply quantity setting of the fuel injection pump only with a delay. To this end, the damping device has a damping chamber defined by a damping cylinder and a damping piston displaceable therein. The damping chamber communicates with the pump interior via two parallel throttles and via counter-parallel check valves located in series with the parallel throttles. The damping piston is connected to a damper lever on which the rpm adjusting lever is supported via a pre-stressed drag spring. The damper lever is connected via a governor spring to a governor lever, which actuates a quantity adjusting device to determine the fuel metering, so that an adjusting motion of the rpm adjusting lever acts upon the quantity adjusting device only in a delayed manner.
    • 在用于机动车辆的内燃机的燃料喷射泵中,设置有阻尼装置,以消除所谓的车辆弯曲。 该装置允许连接到驱动杆的rpm调节杆的快速调节运动仅仅延迟地影响燃料喷射泵的供给量设定。 为此,阻尼装置具有由阻尼缸限定的阻尼室和在其中可移位的阻尼活塞。 阻尼室通过两个平行的节流阀和与平行节流阀串联的反向平行止回阀与泵内部连通。 阻尼活塞通过预应力阻力弹簧连接到减震杠杆上,转速调节杆通过减震杆支撑。 阻尼器杆通过调速器弹簧连接到调速器杆,调速器杆致动量调节装置以确定燃料计量,使得转速调节杆的调节运动仅以延迟的方式作用在量调节装置上。
