Abstract
The invention is a compression method having characteristics of smooth compression and internal cooling of the gas. Embodiments of the invention employ a cylindrical chamber and an orbiting rotor to create a moving duct or chamber whose walls converge, relative to a static gas packet drawn into the moving duct, at a “pinch point”. Preferably the closing speed of the walls is subsonic and the speed of the pinch point is supersonic. This enables high pressure to co-exist, at the narrowing end of the duct, with low pressure elsewhere in the duct, because of the pressure information barrier produced by the supersonic advance of the pinch point. The invention also discloses means for providing gas inlet and outlet functionality, and means for providing a variable flow compressor.
Claims33
A compressor or expander having a rotor and a stator forming a closed volume therebetween and arranged for relative traversal, so as to form a pinch point at the point of nearest proximity, wherein at least one of the rotor and the stator has a movable portion such that the closed volume is controllably variable.
30-35. (canceled)
A method of compressing or expanding a fluid comprising the steps of:
- arranging a rotor and a stator to form a closed volume therebetween, and for relative traversal, so as to form a pinch point at the point of nearest proximity, and
- arranging at least one of the rotor and stator to have a movable portion, such that the closed volume is controllably variable.
