Abstract
A hydraulic motor (1) comprising a casing (2A, 2B) a reaction member having a reaction profile (4), a cylinder block (6), an internal fluid distributor (16) suitable for putting the cylinders (12) of the cylinder block (6) in communication with fluid feed and exhaust ducts, and a braking system which comprises first and second braking elements (42, 44), constrained to rotate respectively with the reaction member (4) and with the cylinder block (6). The braking system further comprises a brake piston (40) suitable for being displaced axially so as to urge the braking elements into braking contact or so as to enable braking to be released. The brake piston is constrained to rotate with the casing about the axis of rotation, and it has a substantially radial active face, a first brake member (42) belonging to the first braking means being integral with said active face.
