The outstanding performance of this motor is the result of an original and petented design The principle is to transmit the effort from the stator to the rotating shaft by means of a pressurized colum of oil instead of the more common connecting rods, pistons, pads and pins.
The oil column is contained by a telescopic cylinder with a mechanical connection at the lips at each end which seal against the spherical surfaces of the cylinder heads and the spherical surface of the rotating shaft.
these lipls retain their circular cross section when stressed by the pressure so there is no alterration in sealing geometry . The particular selection of materials and optimisation of design has minimized both the friction and the leakage
another advantage of this design stems from the elimination of any connecting rods, the cylinder can only expand and retract linearly so there are no transverse components of the thrust. This means no oval wear on the moving parts and no side forces on the cylinder joints.
A consequence of this novel design is a significant reduction in weight and overall size compared with other motors of the same capacity.
