Patent ID: 8444385

Claim:
A phase adjustment mechanism comprising: first and second phase adjustor mounting pieces that are mounted to one another for adjustment relative to one another about a central axis through an adjustment angle; a first phase adjustor connecting component and a first phase adjustor connecting member respectively mounted to the first and second phase adjustor mounting pieces for rotation respectively about a first phase adjustor component axis and a first phase adjustor connecting member axis that are different than the central axis; first, second and third phase adjustor rotational members connected such that a train is created sequentially by the first phase adjustor rotational member, the first phase adjustor connecting component, the second phase adjustor rotational member, the first phase adjustor connecting member and the third phase adjustor rotational member and such that the first and third phase adjustor rotational members revolve in an opposite direction than the second phase adjustor rotational member, the adjustment of the phase adjustor mounting pieces relative to one another through the adjustment angle causing a phase adjustment between the first and third phase adjustor rotational members.
