ABSTRACT:
A steam trap includes an inverted bucket in a bucket chamber. The bucket has a vent hole formed in an upper portion thereof. The vent hole is formed along a vent hole axis, which may be angled so that the bucket rotates from the venting propulsion. The chamber has an outlet orifice formed in a sidewall thereof. There is a spaced vertical distance between the outlet orifice and an upper interior surface of the chamber. Preferably, the bucket is not attached to the chamber and configured to move vertically and horizontally in the bucket chamber, but not flip over. The bucket and the interior sidewalls of the chamber are configured so that the bucket can substantially cover the outlet orifice when the bucket is pulled against the interior sidewall at the location of the outlet orifice by a flow of fluid out of the outlet orifice.
