Abstract

531,655. Valves. MADDOCKS, J. H. July 28, 1939, No. 21975. [Class 7 (vi)] In order to prevent lubricating-oil from leaking down the valve stem, the valve spring washer C is formed with a recess G in which is tightly fitted a metal sealing-washer J. The washer may be initially convex, and be hammered flat by the use of a hollow punch. The lower end of the recess G may be of larger diameter to catch the washer J.
