Billheimer, J C

This patent describes a scroll-type engine for rotating a shaft about an axis of rotation. It comprises a first stator, a second stator coupled to the first stator to define an interior volume therebetween, an orbiting member disposed in the interior volume for movement therein to provide means for defining at least one variable volume working chamber between the orbiting member and each of the first and second stators, an elongated drive post having a longitudinal axis, means for coupling the drive post to the first stator to support the drive post for rotation about its longitudinal axis with respect to the first stator, means interconnecting the drive post and the shaft for converting rotational movement of the drive post about its longitudinal axis to rotational movement of the shaft, and means on the orbiting member for rotating the drive post about its longitudinal axis so that the shaft rotates about its axis of rotation in response to movement of the orbiting member with respect to the first stator in the interior volume, the rotating means including a drive pin coupled to the orbiting member.
