259,330. Millington, W. E. W. July 22, 1925. Steam traps. - In a steam trap of the kind described in Specification 201,951, the floatoperated butterfly valve has its two wings a, b, of unequal length, and is centrally pivoted in the passage d. The passage is either converging or diverging, and the pressure on the unequal wings of the valve assists or retards the closing respectively. Alternatively. the valve may be mounted in a passage with parallel walls, the pivot in this case being necessarily eccentric.
