High Torque Radial Piston Motors MR Type - Fixed displacement Functional description Propulsion: “The fluid column technology” [4] Play video The main concept of this unique and outstanding technology is to convert fluid power (pressure and flow) into mechanical power (torque and speed) by means of pressurized columns of fluid [1] which act directly on a spherical eccentric shaft [2], thereby avoiding the use of conventional connecting rods, pistons, and pins. Torque is generated by the columns of pressurized fluid [1] that directly push the eccentric cam [2] producing the shaft rotation. In...

High Torque Radial Piston Motors MR Type - Fixed displacement Functional description Timing system: “The balanced forces concept” The timing system - consisting of the rotary valve [6] and the reaction ring [7] - supplies the columns of fluid precisely in the correct sequence to generate a smooth motor output torque. While the reaction ring is used to adjust the clearance and to compensate for thermal shocks, the rotary valve rotates at the same speed as the eccentric shaft and connects the reaction ring to the piston chambers by means of two slots [8] and [9]. Two additional balancing slots...
