Abstract:
An axial piston machine (1) including a casing (50) a drive shaft (3) mounted in the casing (50) to rotate about a drive shaft axis (12), a cylinder barrel (2) non-rotatably connected to the drive shaft (3) wherein a plurality of cylinders (5) are formed to accommodate a plurality of axially mobile pistons (6), a control plate (26) with control ports (24, 25) for cyclically connecting the cylinders (5) to a high-pressure and a low-pressure line, and a contact pressure device for preloading the cylinder barrel (2) against the control plate (26), wherein the contact pressure device comprises at least one centrifugal body (30a-30f) which is translated outwardly when subjected to an increasing centrifugal force (F.sub.F) as the speed (n) of the cylinder barrel (2) increases, wherein at least one force redirection member (36-39; 40a-40f, 41a-41f) is provided to convert the centrifugal force (F.sub.F) acting on the centrifugal body (30a-30f) into a contact pressure force which is applied to the cylinder barrel (2) and the contact pressure force has a component (F.sub.A) which is applied to the cylinder barrel (2) in an axial direction to the drive shaft axis (12), and the force redirection member (36-39) is disposed in a cavity (31) between the cylinder barrel (2) and the drive shaft (3).
