Abstract

An inline microgravity air trap device includes an elongate air trap chamber, the air trap chamber having a blind end, an opposite air outlet end containing a gas egress opening, a fluid inlet port connecting to a pressurized fluid supply, a fluid outlet port connecting the air trap chamber to a fluid delivery destination, a filter forming a tube having an interior, a first end at the blind end of the air trap chamber and a second end at the gas egress opening, and a structural insert in the interior of the tube, having a first insert end located at the blind end, and a second insert end located the air outlet end, where the chamber is formed to direct fluid from the pressurized fluid supply to accelerate centrifugally around the filter, forcing gas contained in the fluid to pass through the filter into the interior of the tube.
