About
Suprakash Patra is a mechanical engineer and inventor whose work centers on novel hydrostatic power transmission and fluid power systems. His most significant contribution is the conceptualization and kinematic design of a unique torque amplifier that integrates alternating flow hydraulics with orbital rotary piston motor principles. This system, detailed in his seminal 2002 paper, proposes a hydrostatic machine comprising a multi-piston pump directly connected to an ORBIT motor, a charge pump for leakage compensation, and essential control valves. Patra’s design offers a novel methodology for achieving torque multiplication without conventional mechanical gearing, representing a notable advancement in hydraulic power transmission. While his highly specialized work has accrued a modest citation count, its originality lies in the elegant synthesis of existing hydraulic principles into a compact, high-torque system. For students and researchers in fluid power and mechanical design, Patra’s work provides a foundational example of inventive, application-driven engineering in the niche but critical field of hydrostatic torque amplification.
