A bubble trap comprising a closed container for holding liquid, an inlet extending through the container bottom upward within the container to an inlet opening spaced below the container top, the container having a larger cross-sectional area exclusive of the inlet than the inlet itself, an outlet extending through the container top downward within the container to an outlet opening, the outlet opening being lower in the container than the inlet opening whereby liquid flowing upward through the inlet opening into the container must subsequently flow downward to reach the outlet opening, and means for admitting or removing gas from the container.
