A machine is disclosed that may be configured as a pump, a compressor or an engine. The machine displaces volume by means of pistons that are connected to a driveshaft without oscillating connecting rods. Cylinders are disposed in a rotating cylinder block that rotates on an axis inclined to the axis of rotation of the pistons. A spherical member centers the driveshaft with respect to the cylinder block, and a biasing means urges the cylinder block against a bearing surface. Displacement may be varied by varying the angle of inclination of the two axes of rotation.

A volumetric fluid machine, comprising: a housing; a driveshaft having a first axis; a plurality of pistons connected to said driveshaft and rotatable about said first axis, said pistons projecting from said driveshaft; a cylinder block having a plurality of cylinders, said cylinder block being rotatable within the housing about a rotation center situated on said first axis; a distribution plate having at least one passageway for communication with said plurality of cylinders; said cylinders having an arched-shaped configuration with a concavity facing said rotation center, and with a center of curvature corresponding to said rotation center; said cylinder block being synchronically driven by said pistons on a second axis, intersecting said first axis on said rotation center and being in slideable contact with a sliding surface having an axis corresponding to said second axis to provide a reciprocating movement of said pistons within said cylinders; spherical means on said driveshaft for centering said cylinder block; and biasing means for biasing said cylinder block against said sliding surface.
