Abstract: Compact gas-liquid separator comprising a cylindrical separation chamber including an inlet head and a degasifying vessel. The inlet head comprises an inlet tube supporting a nozzle positioned adjacent to the inner wall of a cover situated within the axis of the separation chamber. The cover includes a cylindrical portion closed by a convex cap and extends toward the bottom by a skirt closing the degasifying vessel and having openings. Within the axis of the nozzle the cylindrical portion has an opening of a diameter greater than that of the nozzle and is spaced from the nozzle. The cover includes a deflector having a central opening and being inclined with respect to the axis of the cylindrical portion of the cover and disposed within the axis of the nozzle. An outlet tube for the gas is positioned in the inlet head.
