System for supplying fluid, particularly fuel e.g. diesel for motor vehicle for use in high pressure injection system of internal combustion engine, has high pressure pump, feed pump and unit for controlling flow rate

摘要

The system (46) has a high pressure pump (1), a feed pump (35) and a unit for controlling the flow rate. The high pressure pump has a drive shaft (2) with a cam (3), a piston (5), a cylinder (6) for bearing the piston and a working chamber (29). The piston is indirectly supported by a cam roller (10) on the drive shaft with the cam, so that a translatory movement is executed on the basis of a rotation of the drive shaft. The unit is the feed pump, which is controllable in the flow rate. An independent claim is included for a high pressure injection system with a high pressure rail.
