Abstract
A single stage, twin valve, variable torque converter has a vaned input impeller, a vaned, single stage output turbine and a twin valve all disposed in a fluid filled, generally torroid-shaped chamber of a housing. The torque converter by means of its twin valve provides a variable forward output torque for a constant input speed and also provides a low reverse torque. The twin valve consists of two connected, concentric cylindrical sleeves which can be moved axially into and out of the torroid-shaped chamber so that the first sleeve can be interposed between the vanes of the input impeller and the vanes of the output turbine and the second sleeve can surround the vanes of the output turbine and thus seal off the output turbine from the fluid within the torroid-shaped chamber of the torque converter and provide a low reverse torque.
