1. An assembly apparatus for assembling a sub-assembly of a swash plate type fluidic apparatus in which a plurality of pistons, each including a pair of spaced apart facing spherical seats with hemispherical shoes placed between said seats, are disposed at predetermined intervals around a swash plate installed on a driving shaft with the pistons and shoes straddling the swash plate, the assembly apparatus comprising:

  • a holder adapted to hold a driving shaft with a swash plate mounted thereon;

    a horizontally extending track;

    a curved track connected with said horizontally extending track and extending circumferentially around an outer peripheral area of said holder for surrounding a swash plate which is mounted on a shaft that is held by said holder;

    a segmented truck including a plurality of carriers articulately connected and adapted to position at predetermined intervals along said truck individual assemblies of a piston with a pair of said hemispherical shoes, said truck being moveable along said horizontally extending track onto said curved track for positioning said carriers with said pistons and shoes thereon in a predetermined relationship equiangularly spaced circumferentially along said curved track;

    transporting means for moving said segmented truck along said tracks;

    a first orienting member disposed for vertical movement between the spherical seats of said pistons when said truck is on said horizontally extending track, said first orienting member having orienting surfaces adapted to position said hemispherical shoes in said spherical seats upon downward movement of said first orienting member; and

    a second orienting member disposed for connecting with said first orienting member when the latter member has descended, said second orienting member having orienting surfaces that incline gradually from a vertical position to the inclination angle of said swash plate and along which said segmented truck is transported as it moves from said horizontally extending track to said curved track, said second orienting member being adapted to guide said hemispherical shoes into position between said spherical seats of said pistons and said swash plate.
