AIR/WATER SEPARATOR FOR DRILL BITS, DRILL BIT AND DRILLING ASSEMBLY COMPRISING SUCH A SEPARATOR AND METHOD FOR DRILLING COMPRISING A DRILL STRING AND SUCH A DRILL BIT

摘要

An air/water separator (100) including a first hollow member (102) configured to receive a flow including an air and water mixture and a second hollow member (104) configured to receive the flow from the first hollow member. An exit (108) of the first hollow member extends into an opening of the second hollow member such that the exit of the first hollow member axially overlaps the opening of the second hollow member, thereby creating a first flow path from the interior of the first hollow member to the outside of the second hollow member including two turns about the exit of the first hollow member and opening of the second hollow member, and a second flow path from the first hollow member through the second hollow member.
