  • Patent number: 11747219
    Abstract: A hydrodynamic-type hydraulic dynamometer is provided. The hydrodynamic-type hydraulic dynamometer includes a shaft rotatably mounted by a plurality of bearings, a stator fixed around the shaft and having a toroidal chamber therein, a runner rotatably coupled to the shaft and causing a fluid introduced into the toroidal chamber to flow therethrough, an inner ring mounted to extend inwardly from a radially outer side of the toroidal chamber and having a control slit formed therethrough, and a shutter configured to adjust an opening degree of the control slit.
