ABSTRACT:
A hydrodynamic torque converter includes a pump wheel, a turbine wheel, and a stator wheel having a variable entrance between the blade rows upon at least one of these wheels, preferably on the stator wheel. The opening between the blades is adjustable automatically by the torque applied by the circulating fluid against the action of a compression spring. The blades on the wheel whose entrance is adjustable includes at least two annular members divided along a plane perpendicular to the axis of the wheel. The annular members are rotatable relative to one another approximately one-half blade pitch. The annular member becomes located in the inlet region of the blade row, is rotatable by the torque of the circulating flow only in the region of the installed condition against the force of the spring to a position that reduces the inlet cross section of the blade row.
