The pump impeller and the turbine runner in a hydraulic torque converter___________________?
Correct answer: A. Have different diameters
- A. Have different diameters
- B. Have the same diameter
- C. Are directly coupled
- D. None of these
Explanation
A hydraulic torque converter contains separate pump and turbine elements designed for different functions, so their runner or impeller dimensions need not be identical. They are also not directly coupled, since torque is transmitted hydraulically.
