Abstract:
An apparatus for evacuating condensate water from a pipe comprising:an inner cylinder concentrically affixed to an outer cylinder by an annular wall disposed between said inner cylinder and said outer cylinder wherein said annular wall divides the space between said inner cylinder and said outer cylinder into an input side pipe groove and an output side pipe groove; further comprising an inside diameter of an input end of said outer cylinder which is about slightly greater than an outside diameter of a mating input pipe; an inside diameter of an output end of said outside cylinder which is about slightly greater than an outside diameter of a mating output pipe; an outside diameter of an input end of said inside cylinder which is about slightly less than an inside diameter of the mating input pipe; a plurality of ribs protruding from an outside surface of said inner cylinder and extending generally parallel to a central axis of said inner cylinder and said outer cylinder wherein said plurality of ribs are sized to provide an interference fit with an inside surface of an output pipe and wherein said ribs leave an annular space adjacent to an output facing side of said annular wall; at least one boss protruding into said output side pipe groove wherein said at least one boss forms a pipe-stop which prevents an output side pipe from abutting said annular wall; and at least one edge defining a drain hole passing through said outside cylinder and into said output pipe groove proximate to said annular wall.
