Abstract

The invention relates to a hydrostatic axial piston machine having a cylinder block which can be rotated about a first axis, the cylinder block being provided with a plurality of cylinder bores which extend in the axial direction and which are arranged on a partial circle which is concentric in relation to the first axis, in addition to a plane which can be rotated about a second axis, whereon a number of pistons associated with the bores, can be articulated in a pivotable manner on a second partial circle which is concentric in relation to the second axis and form a ring. Also provided is a device for synchronizing the rotation of the cylinder block about the first axis and the drive shaft about the second axis. The cylinder block and the drive shaft can be adjusted in a continuous manner using both axes, between a first position, wherein both axes are parallel, and a second position, wherein both axes together form a maximum pivoting angle which is different from zero.
