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 drawing shows a longitudinal section of an axial piston pump 1 with a swash plate drive 2 and wet-running electric motor 3, the electric motor 3 has a drive shaft 4 Drive disc 5 on.
- check valves 17, 18 designed as leaf spring valves 23, 24 and between valve disk 13 and housing 12 or valve disk 13 and cylinder piece 11 are clamped.
- 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 is placed with a centering recess 27 on the centering pin 26.
- the spring rocker 25 is achieved that a piston a suction stroke and the other one Pressure stroke executes.
