The first portion (26) has a cavity (38) therein with a liquid inlet (40) and a liquid outlet (46). The cavity (38) is disposed around at least a portion of the first passageway (42) such that the gas outlet (44) is disposed radially inward of the liquid outlet (46) from the cavity (38). The second portion (28) is connected to the first portion (26) and has a second passageway (48) with an outlet (32).
