Abstract
A gas elimination device for cellular fluids has a cylindrical chamber that is divided radially into two parts by a cylindrical filter centrally located in the chamber. The fluid inlet is directed tangentially to the outer part of the chamber to create a vortex flow. The vortex flow is stopped by passage of the fluid through the filter, and gas bubbles that have formed rise to the top of the outer part of the chamber. A hydrophobic membrane covers the top of the chamber and allows the gas to exit the chamber to the atmosphere. A one way valve formed in a two part cap covering the chamber prevents flow of air into the chamber. A float valve stops flow when the chamber fills with air.
