Abstract:
1. A fluid transfer engine comprising: a case with a cylindrical inner wall having an operating radius extending from a case axis: a main rotor carried for rotational motion with respect to the case and having a lobe with a major radius equal to and concentric with the operating radius, said main rotor having a minor radius defining a body: two peripheral rotors diametrically opposed with respect to the case axis and rotating within rotor chambers extending from the case, each rotor having a radius equal to the minor radius and a center of rotation located at twice the minor radius from the case axis, each of said peripheral rotors rotating in uniform circular motion with the main rotor in sealing contact with the body and having a sculpted recess for receiving the lobe of the main rotor; and, an axle supporting the main rotor for rotation within the case and wherein the lobe includes a first port on an advancing surface of the lobe and a second port on a retreating surface of the lobe, said first port communicating with a first conduit in the axle and said second port communicating with a second conduit in the axle.
