摘要： A distributor type fuel injection pump has a distributor shaft (19) stiffly coupled to a driving shaft (13). When rotated, the distributor shaft successively supplies injection nozzles (29) with fuel from a pump working chamber (22). Pump pistons (21) are slidingly mounted each in a radial bore (20) among a plurality of radial bores (20) arranged in the distributor shaft (19). The pump pistons (31) on the one hand delimit the pump working chamber (22) and on the other hand are frictionally connected to a coaxial cam ring (26) through rollers (24) held in roller saddles (23). In order to simplify the manufacture of the injection pump, the driving shaft (11) grasps the distributor shaft (19) with a cup-like coupling head (34). A number of axial slots (35) that corresponds to the number of radial bores (20) is arranged in the cup wall to slidingly receive the roller saddles (23). Coupling is ensured by a coupling disk (37) provided with radial coupling projections (371-374) that form-fittingly enter the axial slots (35), and with a recess (38) into which a front journal (39) of the distributor shaft (19) is form-fittingly received (fig. 1).

摘要： The fuel injection pump has a piston (12) acting in a cylindrical boring (10) of a cylindrical bush (11). In the cylindrical boring (10), a pump working chamber (40) is limited by the piston (12) on one side and an electrically controlled valve (32) on the other. The pump working chamber (40) can be connected on the intake stroke of the piston (12) with an intake chamber (18) via the valve (32) to control the injection piston stroke. The cylindrical bush (11) is partly surrounded by an annular space (41) through which the fuel flows between the pump working chamber (40) and the inner chamber (18). From the annular space (41) branches a by-pass (43) through which the fuel flows into a further annular chamber (48) partly surrounding the valve (32). The annular chamber (48) is relieved towards the fuel tank via a return line. The two annular chambers (41, 48) have fuel flowing continuously through them owing to the pressure prevailing in the inner chamber (18), thus providing cooling for the pump working chamber (40) and the valve (32).

摘要翻译：分配式燃油喷射泵具有刚性连接到驱动轴（13）的分配器轴（19）。当旋转时，分配器轴从泵工作室（22）连续地向喷嘴（29）供应燃料。泵活塞（21）各自滑动地安装在布置在分配器轴（19）中的多个径向孔（20）中的径向孔（20）中。泵活塞31一方面限定泵工作腔22，另一方面通过保持在滚动鞍座23中的滚子24与同轴凸轮环26摩擦连接。为了简化注射泵的制造，驱动轴（11）用杯形连接头（34）抓住分配轴（19）。对应于径向孔（20）的数量的多个轴向狭槽（35）布置在杯壁中以滑动地容纳滚轮鞍座（23）。联轴器通过设有径向联接突出部（371-374）的联接盘（37）来确保，该径向联接突出部（371-374）形成配合地进入轴向槽（35），并且具有凹槽（38），分配器的前轴颈（39）轴（19）形状配合地接收（图1）。

A fuel injector with means for reducing pressure oscillations is therefore created in the at least one return line which operates without a leakage flow and has a simple and effective function.

摘要： The invention relates to a fuel-injection valve comprising an outer valve needle (15), which co-operates with a valve seat by means of a longitudinal displacement (20), to open and close at least one outer injection orifice (22). An inner valve needle (17) is situated in the outer valve needle (15), said inner needle co-operating with the valve seat (20) by means of a longitudinal displacement to open and close at least one inner injection orifice (24). The fuel pressure in a control chamber (28) that can be filled with pressurised fuel acts on the outer valve needle (15) and the inner valve needle (17) in such a way that a closing force is exerted in the direction of the valve seat (20) on said inner valve needle (17) and outer valve needle (15). The inner valve needle (17) is provided with an inner pressure surface (48) and the outer valve needle (15) is provided with an outer pressure surface (49), which, when pressure is applied, exert a respective hydraulic opening force on the inner valve needle (17) and the outer valve needle (15) in opposition to the closing force. The outer valve needle (15) is at least partially surrounded by an inlet chamber (12), in which pressurised fuel is constantly available, the inner pressure surface (48) and the outer pressure surface (49) being constantly impinged by the fuel in the inlet chamber (12).

摘要： Une pompe d'injection de carburant comprend un piston (12) qui fonctionne dans un alésage cylindrique (10) d'une douille cylindrique (11). Une chambre de pompage (40) est délimitée dans l'alésage cylindrique (10) d'une part par le piston (12) et d'autre part par une soupape (32) à commande électrique. Pendant la course d'aspiration du piston (12) et afin de commander la course du piston qui provoque l'injection, la chambre de pompage (40) peut être reliée par la soupape (32) à une chambre d'aspiration (18). La douille cylindrique (11) est partiellement entourée d'un espace annulaire (41) à travers lequel le carburant s'écoule entre la chambre de pompage (40) et la chambre intérieure (18). Le carburant s'écoule dans un autre espace annulaire (48) qui entoure partiellement la soupape (32) par un conduit de dérivation (43) qui part de l'espace annulaire (41). L'espace annulaire (48) est déchargé au moyen d'un conduit de retour au réservoir de carburant. Compte tenu de la pression qui règne dans la chambre intérieure (18), les deux espaces annulaires (41, 48) sont traversés en continu par du carburant, ce qui assure le refroidissement de la chambre de pompage (40) et de la soupape (32).
