Rotational phase difference adjusting means
First Claim
1. A rotational phase difference adjusting means for adjusting a rotational phase difference between a first rotational member and a second rotational member, comprising,an input member connected to the first rotational member to be rotated thereby,an output member arranged coaxially with the input member and connected to the second rotational member to rotate it,a differential means for connecting the input member to the output member to be rotated thereby and for generating a difference in rotation between the input member and the output member, anda damping means including a viscous fluid which is arranged between the input member and the output member so that a vibration of a relative movement between the input member and the output member is absorbed by a viscosity of the viscous fluid, and including a sealing means for holding the viscous fluid between the input member and the output member against a slide movement of the sealing means between the input member and the output member, whereinthe slide movement of the sealing means is carried out on a plane extending substantially perpendicularly to the axis of the input and output members.

Abstract
A rotational phase difference adjusting device for adjusting a rotational phase difference between a first rotational member and a second rotational member, comprises, an input member connected to the first rotational member to be rotated thereby, an output member arranged coaxially with the input member and connected to the second rotational member to rotate it, a differential device for connecting the input member to the output member to be rotated thereby and for generating a difference in rotation between the input member and the output member, and a damping device including a viscous fluid which is arranged between the input member and the output member so that a vibration of a relative movement between the input member and the output member is absorbed by a viscosity of the viscous fluid, and including a sealing device for holding the viscous fluid between the input member and the output member against a slide movement of the sealing device between the input member and the output member, wherein the slide movement of the sealing means is carried out on a plane extending substantially perpendicularly to the axis of the input and output members.
