Abstract
A high-pressure pump for supplying fuel in a fuel injection system of an internal combustion engine, including a common rail injector system. The fuel injection system includes a low-pressure part that contains a fuel tank and a prefeed pump and a high-pressure part that contains a high-pressure pump and a common rail into which a fuel flow is fed from the high-pressure pump through a common conduit. The high-pressure pump system solves a problem in that there is an integrated demand-based quantity control for the fuel flow pumped by the high-pressure pump. The demand-based quantity control integrated with the high-pressure pump contributes to improving the overall engine efficiency, because the power consumption by the high-pressure pump drops as a result.
