A hydrostatic rotating machine includes an internal element and an external element that revolve with respect to one another about an axis of rotation, a cylinder block, and a hydraulic distributor. The hydraulic distributor includes an insertion section extending axially between a section of lesser diameter and a section of greater diameter, with a first synchronization surface, and fluid distribution ducts which each have an end segment opening transversely at the first synchronization surface, and obliquely with respect to the axis of rotation. The cylinder block includes a reception section complementing the insertion section of the hydraulic distributor, and fluid diffusion ducts which each have an end segment opening transversely at the second synchronization surface, and obliquely with respect to the axis of rotation.
