ABSTRACT:
A rotary apparatus uses vanes which oscillate with respect to one another, while simultaneously rotating within a chamber, to compress a gas or pump a liquid. The oscillating motion results from interaction of at least a single coupled pair of elliptical drive members. When the driver elliptical member is rotated at a constant angular velocity, it causes the driven elliptical member to rotate with a varying angular velocity. As the driven elliptical member is connected to at least one vane, that vane also rotates with a varying angular velocity. In a preferred embodiment, two pairs of meshing elliptical gears drive four vanes with an oscillating and rotating motion.
