A sliding shoe for supporting a piston of a hydrostatic axial piston machine against a swash plate includes a sliding face that defines a central concentric pressure pocket that is flat in order to stabilize the sliding shoe. The pressure pocket has radial supply grooves in order to ensure an optimal supply of pressure medium to the pressure pocket from a central mouth opening. The radial supply grooves extend through the pressure pocket and as far as a circumferential groove which surrounds the pressure pocket.

A sliding block for a piston of a hydraulic piston machine, includes a concave recess to receive a piston head and a sliding surface to support the piston. A lubricant channel passes through the sliding block from the concave recess to the sliding surface, and the concave recess transforms with a constant tangent i.e. without kinking into a transition segment of a constantly narrowing taper segment of the lubricant channel. The transition segment is convex.

The invention relates to a fuel injector comprising a nozzle retainer or an injector body, a valve body and a nozzle body, in which a preferably needle-shaped injection valve member is arranged to be vertically movable, said member releasing or closing at least one injection port leading to a combustion chamber of an internal combustion engine depending on the pressure relief of or the pressure load on a control chamber. The invention is characterized in that a valve comprising a preferably ball-shaped valve element is arranged in the nozzle retainer or in the injector body for the pressure relief of the control chamber.
