Abstract
A housing structure for a hydrostatic machine comprising two shells of part-cylindrical form. The shells are connectable together at their junction surfaces on a parting-plane. A drive-shaft is supported in the housing structure and its axis of rotation lies on the parting-plane, this being the axis of symmetry of the shells. The shells are identical in cast shape, and have symmetrically arranged recesses and surface features to either side of said axis of symmetry. In the interior chamber between the shells, working component elements of the machine are located and driven by the drive-shaft to convert mechanical power into hydraulic power passing through openings or fluid-passageways provided in the housing structure.
