A scroll-type engine includes an orbiting member situated inside the interior volume of the engine to define a compression chamber and an expansion chamber. The orbiting member includes an aperture for transferring an air and fuel mixture from the compression chamber to the expansion chamber. A spiral wrap found on a first stator of the engine provides a valve for controlling flow through the aperture in response to movement of the orbiting member relative to the first stator. A drive post is coupled to the first stator for rotation about its longitudinal axis. A drive pin formed on the orbiting member engages the drive post to rotate the drive post about its longitudinal axis in response to movement of the orbiting member relative to the first stator. The engine also includes a mechanism for converting rotational movement of the drive post to rotational movement of a crank shaft of the engine.
