Abstract

320,830. Andrews, H., and Andrews, A. Jan. 25, 1929. Seats.-A new seating for a poppet valve is provided by machining out a recess a around the cylinder port b, and by forcing therein a ring d which is machined to be a smooth driving fit in the recess and to provide a lip e at the bottom, which becomes forced outwards into an undercut groove c at the bottom of the recess. The ring d is preferably of centrifugally-cast iron.
