ABSTRACT:
In a rotative machine for fluids which includes a plate formed with spiral-like passages extending from a central orifice to an annular interval and which also includes, facing the passages, a support rotatably mounting vane wheels for rotation about axes which are perpendicular to the axis of rotation of said plate, the vanes of said vane wheels have a dimension at their attachment to the body of the vane wheels which is different from that at their frontal side, permitting manufacture of the plate by simple die-casting. A method is also provided for determining the contour for both the passages and the cooperating sliding surfaces of the plate and the support for the vane wheels which will result in the maximum output for the machine.
