Title: RELEASE MECHANISM FOR TRAPPED AIR IN A FLUID FLOW DEVICE
Abstract:
Mechanisms and methods for minimizing trapped air in a fluid flow device are disclosed. An example device includes a first chamber having an inlet and outlet for substantially horizontal fluid flow, a second chamber at least partially openly disposed above the first chamber, and a tube vertically disposed in the second chamber from the second chamber ceiling to the first chamber. When fluid flows from the inlet to the outlet, at least a portion of the fluid flows into the second chamber and air collected at its ceiling moves down the tube and into the first chamber. The ceiling of the second chamber may be contoured such that a first internal height at a first location of the second chamber is greater than a second internal height at a second location, forming a pocket at the ceiling at the first location where air can collect before entering the tube.
