ABSTRACT:
A radial-piston machine has a rotor formed with a plurality of axially extending slots in each of whose bases is formed a piston-carrying radial cylinder. Each such piston is formed on its radially outer end with a part-spherical seat and a part-spherical portion of a respective piston shoe that rides on an eccentric cam in the housing is engageable in each seat. Each such piston shoe can move radially into and out of engagement with the respective piston. A pair of end members axially flank the piston shoes with play so that these shoes may also move axially relative to the rotor. The piston-engaging portions of the shoes are slightly narrower than the respective cross-slots so that angular free play is also present, and these portions are always engaged radially in the slots.
