Abstract
The disclosure concerns a hydrodynamic brake with a rotor blade wheel and an opposed stator blade wheel together defining a toroidal working chamber for containing working fluid. The blades of one or both of the blade wheels are swingable about respective radial axes so as to be skewed at an oblique orientation when the rotor blade wheel is rotated with working fluid in the working chamber. The blades are swingable from a first skewed orientation caused by one direction of rotation of the rotor blade wheel, to an idle orientation at which the blades are generally parallel to the axis of the brake and to an opposite skewed orientation which occurs when the rotor blade wheel rotates in the opposite direction. The torus wall outside the outside edges of the swingable blades is separated into independent sections and the torus wall sections are attached to respective blades for swinging therewith. In one embodiment, two neighboring blades are joined by a torus wall section, thereby defining a U-shaped cross-section blade member.
