Abstract
A self-cleaning bleeder valve comprises an annular housing that is mounted in an opening in a pressure vessel, and a valve member that screws into the housing for movement toward and away from an orifice opening in the housing. The valve member includes a gasket seal and orifice drill at an inner end of the valve member. The orifice is positioned such that when the valve member is screwed into the annular housing, the drill extends through the orifice, automatically cleaning the orifice while restricting the rate of gas flow out of the orifice to the space between the drill and the orifice.
