ABSTRACT:
An improvement on U.S. Pat. No. 4,058,240 in which the condensate is collected in cavities in the valve member having open ends on opposite sides of a plane normal to the valve member and perpendicular to its axis of rotation. The inner ends of the cavities intersect a vent opening extending along the axis of the valve member. The material of the valve member between the cavities provides better support for the valve seals. The vent provides more rapid drainage of the cavities so the cavities are substantially completely emptied each revolution, thereby increasing the drainage capacity of the device. The ball valve member could be hollow, in which case the entire interior of the ball would be available for collecting condensate.
