The invention concerns an hydraulic motor pump (1) having a fixed or variable cylinder capacity and comprising a central motor pump rotor (3) in which is disposed an hydraulic cylinder (14), the rotor (3) being in sealed contact with an input-output distributor (43) connecting the cylinder (14) to a motor pump frame (2) whilst an hydraulic piston (13) moves in the cylinder (14) in order to push, by means of an hydraulic piston guided tappet (18), a tangential arm (22) articulated in the central rotor (3) and a tangential arm anti-friction roller (28), on a peripheral motor pump rotor (29) which is synchronized for rotation with the central motor pump rotor (3).
