Abstract
A mechanism is adapted to clean a filter of a steam trap by opening a valve at one end of the filter by turning an adjusting screw secured to one end of the valve without shutting down a boiler in which a flow path is formed from one end of the filter to a drain via the valve and the adjusting screw after the valve opening. A stop projects into the valve for preventing the adjusting screw from disengaging the valve by stopping an annular flange of a valve cone in the valve opening operation.
