Hydrostatic machine with assembled cam ring and annular housing

Abstract

Hydrostatic radial piston rotation machine comprising an internal element (1) and an external element (2) coaxial and mounted to rotate relative to each other around an axis of rotation (R), one of these elements being a rotor and the other of these elements being a stator; the internal element (1) comprising a cylinder block (10); the external element (2) comprising an annular housing (5) surrounding the cylinder block (10), as well as a cam ring (9) mounted in the annular housing (5). The cam ring (9), on its external circumference, and the annular housing (5), on its internal face, each comprise a fitting profile, one of these fitting profiles being a concavity, and the other of these fitting profiles being a convexity (38), the two fitting profiles being of complementary shapes and being fitted into each other.
