Patent ID: 8726941

Claim:
An exit assembly comprising: a fluid inlet; an exit chamber; a fluid outlet, wherein the fluid outlet is located within the exit chamber; and a fluid diverter, wherein the fluid diverter is connected to the fluid inlet and the exit chamber, wherein a fluid is capable of flowing from the fluid inlet, through the fluid diverter, and into the exit chamber, wherein the fluid flows through the fluid diverter in an unobstructed manner, and wherein the shape of the fluid diverter is selected such that the fluid diverter is capable of displacing the pathway of the fluid from the fluid inlet into a first fluid pathway, a second fluid pathway, and combinations thereof, wherein the first fluid pathway and the second fluid pathway are located within the exit chamber, wherein the fluid flowing in the first fluid pathway flows within the exit chamber in a first direction and the fluid flowing in the second fluid pathway flows within the exit chamber in a second direction, wherein the first direction is in a rotational direction about the fluid outlet and the second direction is in a direction axial to the fluid outlet, and wherein the exit chamber is designed such that a higher viscosity, higher density, or lower flow rate fluid will flow in the second direction, while a lower viscosity, lower density, or higher flow rate fluid will flow in the first direction.
