Title:
METHOD FOR PRODUCING METALLIC-SODIUM-FILLED ENGINE VALVE
Document Type and Number:
WIPO Patent Application WO/2011/104923
Kind Code:
A1
Abstract:
In the disclosed method, an engine valve (V) filled with metallic sodium (Na) within is produced by means of hardening metallic sodium (Na)—that has been liquefied through heat-melting—into rods by linearly discharging the metallic sodium (Na) in a liquid hydrocarbon (120), thus cooling the metallic sodium, then inserting these rods into a hollow section (H) through the opening (M) of a stem section (S), and then sealing the opening (M).
