  • Closed-loop waterbrake dynamometer fluid volumetric control system and method
    Patent number: 7032464
    Abstract: A waterbrake dynamometer fluid volumetric control system and method includes a closed-loop recirculation passage to maintain a substantially constant fluid volume within the waterbrake. Fluid volume within the waterbrake is controlled by selectively supplying fluid to, and removing fluid from, the waterbrake.
    Type: Grant

  • Modulator water dynamometer
    Patent number: 7029233
    Abstract: A modular waterbrake that can be used with differing types and sizes of rotating machines includes common end stages, and a plurality of common intervening power stages. Each power stage will extract a certain amount of shaft horsepower from the machine under test, and each stage operates independently of one another. Thus, the modular water dynamometer can be used to zero in on desired torque test loads during machine testing, by simply activating or deactivating selected stages.
