Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
125 words
IN COMBINATION, A VORTEX CHAMBER INCLUDING A PERIPHERAL WALL AND AN ORIFICE FOR EGRESS OF FLUID FROM SAID VORTEX CHAMBER, SAID ORIFICE LOCATED CENTRALLY WITH RESPECT TO SAID PERIPHERAL WALL AND HAVING A RADIUS SUBSTANTIALLY LESS THAN THE RADIUS OF SAID WALL, AND MEANS FOR SUPPLYING OPPOSED FLUID STREAMS TO SAID CHAMBER, SAID MEANS BEING DIRECTED SO THAT EACH OF SAID STREAMS IS DISCHARGED INTO SAID CHAMBER ECCENTRICALLY OF SAID ORIFICE SO AS TO CREATE A VORTICAL FLOW PATTERN IN RESPECTIVE OPPOSITE SENSES AT SAID ORIFICE WHEREBY, THE ROTATIONAL VELOCITY AND DIRECTION OF THE VORTICAL ROTATION FROM SAID ORIFICE IS A FUNCTION OF THE DIFFERENTIALS IN PRESSURE BETWEEN THE FLUID STREAMS ENTERING SAID CHAMBER, SAID FLUID STREAMS BEING THE ONLY FLUID SUPPLIED TO SAID CHAMBER.
