This device intended essentially for maintaining the mutual swivel engagement between a swash-plate engaging shoe and a piston in a barrel-type hydraulic pump or motor, of the type comprising a swivel ball rigid with the shoe and adapted to engage a corresponding cavity in the relevant piston, comprises a ring, a groove formed in said piston cavity and engageable by said ring, the configuration of said retaining member and groove being such that the retaining member can be fitted without play, while preserving the possibility of taking up plays due to manufacturing tolerances while safely retaining the shoe by virtue of a wedging effect. |
