ABSTRACT:
A variable-speed motor comprising a sun gear (P), at least two planet gears (Si, Si+1), a ring gear (C), an intermediate sector (Zi) between the sides opposite the sun gear (P), opposite the two planet gears (Si, Si+1), and opposite ring gear (C), defining the circulation paths of the drive fluid therewith. The junctions (J(P, Si), J(Si, C), J(Si+1), C), J(P, Si+1)) are impermeable to the drive fluid. The two inlets (Ai, .alpha.i+1) and the two returns (Ri, .rho.i+1) for the drive fluid are provided in sector (Zi) in the vicinity of the junctions; the inlets (Ai, .alpha.i+1) and the returns (Ri, .rho.i+1) are located at two opposite vertices of the quadrilateral.
