Abstract
An automatic air eliminator includes an elongated housing defining an interior chamber having a top wall, a bottom wall and a substantially cylindrical side wall centered on an axis. A vent opening is present in the chamber top wall and a hydrophobic membrane covers the vent opening. The housing has a fluid outlet passage centered on the axis in the bottom wall of the chamber and a fluid inlet passage in the chamber side wall at a location adjacent to the top wall. That inlet passage is curved about the axis so that fluid inflow to the passage enters the chamber tangentially and circulates about the axis to the fluid outlet to minimize fluid turbulence and to maximize the residence time of the fluid housing.
