AI summary

A fluid transfer engine employs a case with a cylindrical inner wall having an operating radius extending from a case axis. A main rotor is carried within the case and incorporates a lobe with a major radius equal to and concentric with the operating radius of the case, the main rotor having a minor radius defining a body. Two peripheral rotors are diametrically opposed with respect to the case axis and rotate within rotor chambers extending from the case. Each peripheral rotor has a radius equal to the minor radius and a center of rotation located at twice the minor radius from the case axis. Each of the peripheral rotors rotates in uniform circular motion with the main rotor in sealing contact with the body and incorporates a sculpted recess for receiving the lobe of the main rotor.
