Abstract
At least two rotors are mounted in a chamber and rotate synchronously to compress and/or transport fluid. The chamber has the shape of partially overlapping circles with each circle intersecting the center of the adjacent circle. The rotors are non-eccentric and have curved sides with the same radius as the circles. In exemplary embodiments, the rotors are trochoidal and the chamber is epitrochoidal. Also provided are compressors, pumps, actuators, and engines incorporating the rotary machine.
Claims34
A rotary device, comprising:
- a housing defining at least one chamber having a shape defined by two or more partially overlapping circles, one or more inlet ports in fluid communication with the chamber, and one or more outlet ports in fluid communication with the chamber;
- two or more rotors that cooperate to temporarily define one or more compression sub-chambers and one or more suction sub-chambers as the rotors rotate synchronously within the chamber;
- and
- a linkage for synchronously rotating the rotors.

A rotary device, comprising:
- a housing having a side wall defining at least one chamber with an epitrochoidal shape defined by two partially overlapping circles, wherein each one of the circles intersects a center of an adjacent one of the circles and both of the circles have the same radius;
- one or more inlet ports and one or more outlet ports defined in the housing in fluid communication with the chamber, wherein the inlet ports and the outlet ports are positioned in corners of non-overlapping parts of the circles, each of the corners being defined by the housing side wall and an arc of an overlapping part of an adjacent one of the circles;
- two non-eccentric rotors each having a trochoidal shape with curved outer, leading, and trailing sides all having the same radius as the circles defining the chamber, the rotors cooperating to temporarily define two compression sub-chambers and two suction sub-chambers as the rotors rotate synchronously within the chamber through a 360-degree rotary cycle, wherein the compression sub-chambers are formed by the outer side of a leading one of the rotors, the leading side of a trailing one of the rotors, and the chamber side wall, wherein the suction sub-chambers are formed by the trailing side of a leading one of the rotors, the outer side of a trailing one of the rotors, and the chamber side wall, and wherein the compression sub-chambers and the suction sub-chambers are not formed by the rotors when the rotors turn through non-overlapping parts of the circles in two neutral phases;
- and
- a linkage for synchronously rotating the rotors.
