Abstract
Abstract The invention concerns a torque converter in which multidirectional input is converted to unidirectional output. The invention also concerns a rotary engine giving multidirectional output in combination with the converter to give unidirectional output therefrom. The converter includes two unidirectional clutches, one reversed with respect to the other, and a reversing means for enabling input in both clockwise and anticlockwise directions to be converted to unidirectional output.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
158 words
A torque converter comprising a casing having mounted therein at least one input shaft, at least one output shaft, a first unidirectional clutch mounted on an input shaft to transmit motion in one direction on rotation of said input shaft, a second unidirectional clutch mounted on the same input shaft to transmit motion on rotation of the input shaft in the opposite direction, means for reversing one of said directions of motion whereby the output shaft may rotate in a single direction irrespective of the direcTion of rotation of the input shaft, and an output shaft reversing means comprising a third unidirectional clutch mounted on the said input shaft to transmit rotation in the same direction as the first unidirectional clutch from the said input shaft to drive the output shaft in the opposite direction to that driven by the first unidirectional clutch, only one of the first and third unidirectional clutches being operable at any one time.
