ABSTRACT:
An axial piston machine comprises first and second members arranged so that one of the first and second members is swingable relative to the other to provide relative swinging motion, a plurality of pistons inserted in a plurality of cylinders formed in the second member, respectively, the pistons being mechanically engaged with the first member so that the relative swinging motion reciprocates the plurality of pistons in the cylinders, and a swinging mechanism for swinging the above-mentioned one of the first and second members relative to the other, and the axial piston machine is characterized in that the first and second members have spherical portions providing a coupling portion binding one of the first and second members to a spherical point of the other to be universally rotatable about the point, and the above-mentioned swinging mechanism comprises a relative revolving mechanism for revolving at least one of the first and second members relative to the other to provide a relative swinging motion between the first member and the second member, thereby to reciprocate the pistons.
