Abstract:
An apparatus for separating entrained air from a liquid includes a chamber extending vertically and having a bottom end and a dome-shaped top end. A divider is provided within the chamber dividing the chamber into an intake cavity and an exit cavity. The divider also forms a passage way near the top end of the chamber connecting the intake cavity and the exit cavity. The liquid enters the intake cavity through an inlet which has a smaller cross-sectional area than the intake cavity. The resulting increase in the liquid's volume causes pressure drop, in turn, causing the entrained air to coalesce into larger air bubbles and rise to the top of the liquid. As the liquid flows through the passage way, the separated air escapes through a bleed hole provided in the top end of the chamber.
