ABSTRACT:
A first part of an engine valve (10) is centered on an axis (A) and comprises a hollow metal member (100) having an outwardly flared first end portion (102) and a second end portion (104). The hollow metal member (100) has a chamber (106) extending axially throughout the member. The chamber (106) is open at the first end portion (102). A second part of the engine valve (10) is centered on the axis (A) and comprises a metal piece (130) coaxial with the hollow metal member (100). The metal piece (130) has first and second ends (132 and 134). The first end (132) has a first weld connection to the second end portion (104) of the hollow metal member (100). The metal piece (130) has a solid cross-section portion between the first and second ends (132 and 134). The metal piece (130) has a circumferential groove (150) in the solid cross-section portion. A metal cap (160) has a periphery (166) and a second weld connection (172) at the periphery to the outwardly flared first end portion (104) of the hollow metal member (100). The cap (160) closes the chamber (106) of the hollow metal member (110) at the flared first end portion (104). An inner surface (162) of the cap (160) is conical in shape and tapers axially away from the hollow metal member (100) as the inner surface (162) extends from the periphery (166) toward the axis (A). The cap (160) has an outer surface (164) which is conical in shape and tapers axially away from the hollow metal member (100) as the outer surface (164)) extends from the periphery (166) toward the axis (A).
