Device for driving of pump, especially high-pressure fuel pump for internal combustion engine, has crankshaft driven gearwheel and pump drive pinion with step-up transmission of 1 to 2, 3, or 4

摘要

The device is for the driving of a pump (1), especially a high-pressure fuel pump for an internal combustion engine with a crankshaft driven gearwheel (2) meshing with a pump drive pinion (1') via an intermediate gearwheel (3). The crankshaft driven gearwheel and the pump drive pinion has a step-up transmission of 1 to 2, 3, or 4. A chain wheel (4) is installed co-axially on the intermediate gearwheel, and a traction chain or belt is wrapped around the chain wheel and a camshaft drive wheel (6,6').
