Definitions

  • the invention relates to an axial piston pump with a swash plate drive according to the preamble of claim 1.
  • Such an axial piston pump is known as a high pressure pump from DE 85 14 497 U1, whose interior is filled with an oil.
  • an axial piston pump is known, which is used as a fuel pump to be used.
  • This pump also has an insulated interior that is filled with lubricating oil.
  • the pistons 10 are loaded by a common spring rocker 25, which is supported on a centering pin 26 of the cylinder piece 11, the swash plate 8 with a centering recess 27 is placed on the centering pin 26.
  • the spring rocker 25 is achieved that a piston a suction stroke and the other one Pressure stroke executes.
