Torque Converter Working Principle - Hydraulic Coupling & Fluid Dynamics Explained #1861755 (License: Personal Use)

This technical illustration depicts the internal mechanics of a hydraulic torque converter, highlighting the impeller (driven by the engine at ω₁), turbine (output to transmission at ω₂), and stator (redirects fluid flow). The right-side insets demonstrate how fluid velocity and direction change during acceleration, idle, and coupling phases, emphasizing the slip (ω₂ - ω₁) that enables torque multiplication. Yellow springs represent one-way clutch mechanisms enabling stator freewheeling under certain conditions.

Used in automotive engineering education, repair manuals, and drivetrain system documentation to explain automatic transmission fundamentals; targets students, mechanics, and engineers seeking to understand fluid coupling and torque multiplication principles.
