Hydrostatic axial piston machine in swash plate design, has adjusting piston, which is secured against rotation about its longitudinal axis and has cylindrically curved convex contact surface at its swivel plate-sided front side

摘要

The hydrostatic axial piston machine has a housing (21) and a cylinder drum (4), which is rotatably mounted about an axis of rotation (9) in the housing interior. An adjusting piston (16), which is secured against rotation about its longitudinal axis (22), has a cylindrically curved convex contact surface (18) at its swivel plate-sided front side. The adjusting piston is attached to a flat support surface (26) of the swivel plate (12) through the contact surface. The adjusting piston is made of a hard non-ferrous metal or a non-ferrous metal containing alloy, such as brass or brass alloy.
