摘要： The pump piston in a fuel injection pump is provided with longitudinal grooves which provide communication between the pressure chamber and the fuel supply chamber. An annular groove on the pump piston connects the longitudinal grooves so that communication between the pressure chamber and the fuel supply chamber is interrupted only after onset of the axial pressure stroke regardless of prior piston rotation.

摘要： A fuel injection pump for internal combustion engines has a fuel-quantity adjusting member, and an adjusting device associated with the adjusting member and operative for altering a possible travel of the fuel-quantity adjusting member as a function of an atmospheric pressure. The device has a pivotally mounted two-armed stop lever against which the fuel-quantity adjusting member can be brought to rest. A circuit is provided with a working element which acts on the stop lever and changes its position or length following a closure and opening of the circuit. The adjusting device has a switching element which is acted upon by the atmospheric pressure and, as a function of atmospheric pressure closes and opens the circuit.

摘要： A fuel injection pump for internal combustion engines having a cup-shaped pump housing and a pump head enclosing the housing. The pump head has a cylinder in which a pump piston, which is set into simultaneous reciprocating and rotary motion by a cam drive, in the course of which it simultaneously acts as a distributor, encloses a pump work chamber that is filled with fuel upon an intake stroke and communicates with one of a plurality of injection lines upon the supply stroke. The resultant reaction forces and moments are supported according to the invention via a roller race supported directly on the pump head, and as a result the induction of force to the pump housing can be avoided.

摘要： The invention is based on a fuel injection pump in which to supply a very rapid pressure rise in the interior of a fuel injection pump, a pressure valve controlling this pressure is modified such that upon cold starting of the engine, the pressure valve closes a bypass line at the feed pump and thus delivers all the fuel to the fuel injection pump. The closure is effected as a function of rpm and accordingly pressure, and also as a function of the engine operating temperature; in the fuel injection pump according to the invention, the rpm- and pressure-dependent diversion is performed by the adjusting piston of an injection adjuster. Thus, compared with the known cold-starting accelerating devices, one additional pressure limiting valve can be eliminated.
摘要翻译： 本发明基于燃料喷射泵，其中在燃料喷射泵的内部提供非常快的压力上升，控制该压力的压力阀被改变，使得在发动机冷起动时，压力阀关闭旁路 在进料泵处，从而将所有燃料输送到燃料喷射泵。 闭合作为rpm和相应的压力的函数实现，并且还作为发动机工作温度的函数; 在根据本发明的燃料喷射泵中，通过喷射调节器的调节活塞执行转速和压力依赖性转向。 因此，与已知的冷启动加速装置相比，可以省去一个附加的限压阀。
