More Information
Summary:The present invention relates to a high pressure pump (1), where it is ensured that Ga ≤ Gb < Gc or Ga < Gb ≤ Gc, wherein Ga denotes a clearing (43) between the bore (40) on the portion from the compression chamber (6) of the high pressure pump (1) to the cylindrical groove (42) and the plunger (5), where a transverse aperture (41) is connected with the bore (40) through a cylindrical groove (42) provided halfway through the bore (40) of a cylinder (4); Gb a clearance (44) closer to the cylindrical groove (42), out of the clearances (43, 44, 45) between the bore (40) from the cylindrical groove (42) to the drive source side and the plunger (5); and Gc a clearance (45) closer to the drive source side, out of the clearances (43, 44, 45) between the bore (40) from the cylindrical groove (42) to the drive source side and the plunger (5).
