Abstract:
1. A hydrostatic machine with a cylinder block having sleeve holes formed therein, sleeves seated in said holes and surrounding piston bore, pistons being mounted in said bores for reciprocatory displacement, said pistons extending into the cylinder block so as to define cylinders at front ends thereof, the sleeves each, in a region facing away from the cylinder and at least in a region of a greatest piston radial force pressing the piston against a wall of the piston bore, have an axially-defined recess which is arranged in a region of the center of gravity of the piston in an outer surface thereof, and wherein a throughput volume of the hydrostatic machine is adjustable and the recess is positioned in the region of the center of gravity when the hydrostatic machine is adjusted to a minimum throughput volume.
