ABSTRACT:
A retaining device for axial piston machines embodies a shoe plate with a plurality of openings radially disposed in it. On each side of each opening a substantially flat portion exists to maintain a tangential line of radial contact with the shoes. The shoe plate has a force transferring portion made up of a plurality of raised surfaces. The raised surfaces are arranged to apply two areas of axial contact on each shoe. The two areas of axial contact are generally diametrically opposed which keeps the shoes in sliding contact with the swash plate and thus substantially eliminates tipping of the shoes.
