Abstract:
1. A system for continuously varying relative angular rotation between two cooperating rotary devices each independently working a fluid therein, said system comprising: a first rotary device for working a fluid therein, said first rotary device including a first rotor rotatable about a first rotary axis at a first rotary angular velocity; a second rotary device for working a fluid therein, said second rotary device including a second rotor rotatable about a second rotary axis at a second rotary angular velocity; a first contact wheel disposed in rotational contact with said first rotor at a given radial distance from said first rotary axis; a second contact wheel disposed in rotational contact with said second rotor at a given radial distance from said second rotary axis; a member operatively interconnecting said first and second contact wheels in a fixed rotational relationship; and an indexing device for moving at least one of said first and second contact wheels relative to said respective first and second rotary axes while maintaining rotational contact with said respective first and second rotors for varying the rotary angular velocity of said first rotary device relative to said second rotary device.
