Abstract: In an axial piston pump having an oblique disk, the axial piston pump includes a piston drum with pistons disposed therein that are displaceable by way of a holder that runs along the oblique disk. The angle of engagement of the oblique disk can be increased. On the outer side of a spherical adjustment surface provided on a component of a shaft, there are at least two glide blocks that are rotatable about a rotational mount and that exhibit an axial extent with respect to the drive shaft axis. For the purpose of transmitting torque from the drive shaft to a holder, the glide blocks are engaged with grooves that are provided in the holder, and in particular in the wall of the holder that circumscribes a receiving bore of the holder.
