Patent ID: 7428909

Claim:
A condensation trap, comprising a hollow body comprising: a first portion having a first opening at a first end, a first outer periphery about the first end, and a first inner periphery defining a first flow passage having a curved, first central axis with a constant radius of curvature, wherein the first outer periphery has a first cylindrical outer surface adapted to accept a cylindrical tube fitted over the first end of the first portion, the first cylindrical outer surface having a first centerline that is straight; and a second portion having a second opening and a second inner periphery defining a second flow passage, the second portion having a second central axis, wherein the first flow passage joins the second flow passage such that the first opening is in fluid communication with the second opening, wherein the second central axis intersects the first central axis at an acute angle, and wherein, with the first centerline oriented generally horizontal, a reservoir is formed at the intersection of the first flow passage and the second flow passage that is adapted to retain a volume of liquid at a liquid level that prevents the passage of air from the first opening to the second opening.
