Abstract

604,222. Making poppet valves. EATON MANUFACTURING CO. Aug. 8, 1945, No. 20280. Convention date, May 13, 1944. [Classes 83 (ii) and 83 (iv)] [Also in Group XXVII] Welding.-A poppet valve comprises a stem 10 integral with a head 14 and formed with a blind bore 16 containing sodium or other coolant, and a curved resilient plug 22 welded under pressure on to the chamfered end 20 of the bore. In forming the valve, the stem and head may be forged, and after welding, the plug 22 is machined flush with the head 14. The chamfer 20, and hence the weld, is of greater width than the thickness of the plug 22.
