High pressure pump i.e. radial piston pump, for conveying of fuel to fuel distributor block and common-rail of fuel injection system of internal combustion engine, has pipeline that opens into channels of cylinder heads at sealing points

摘要

The pump (1) has high pressure channels (6, 12) provided in cylinder heads (4, 5), respectively. The pressure channels exhibit respective sealing points (10, 14). A curved high pressure pipeline (21) is clamped between the sealing point (10) at the high pressure channel (6) of the cylinder head (4) and the sealing point (14) at the high pressure channel (12). The high pressure pipeline opens into high pressure channels of the cylinder heads at the sealing points of the high pressure channels, respectively. Sealing cones (11, 15) are provided at the sealing points.
