Abstract:
A power dividing device to provide two rotating outputs having variable relative speed of rotation from a single rotatable input, said device including a first rotational element driven in rotation about a rotational axis and having a first rotational output; a second rotational element rotatable about said rotational axis and having a second rotational output; a first fluid chamber associated with said first rotational element; a first regulator to vary the volume of said first chamber in response to rotation of said first rotational element; a second fluid chamber associated with said second rotational element; a second regulator to vary the volume of said second chamber in response to rotation of said second rotational element; a commutator rotatable in response to rotation of said first rotatable element to at least regularly establish a closed fluid flow communication between said first and second chambers during rotation of said first and second rotational elements; the speed of rotation of said second rotational element in response to rotation of said first rotational element being determined by the respective variations in volume of said fluid in said first and said second chambers.
