摘要： 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).
摘要翻译： 发动机气门（10）的第一部分以轴线（A）为中心，并且包括具有向外扩张的第一端部（102）和第二端部（104）的中空金属构件（100）。 中空金属构件（100）具有沿整个构件轴向延伸的腔室（106）。 腔室（106）在第一端部（102）处是开放的。 发动机气门（10）的第二部分以轴线（A）为中心，并且包括与中空金属构件（100）同轴的金属片（130）。 金属片（130）具有第一和第二端（132和134）。 第一端（132）具有与中空金属构件（100）的第二端部（104）的第一焊接连接。 金属片（130）在第一和第二端（132和134）之间具有实心的横截面部分。 金属片（130）在实心截面部分具有周向槽（150）。 金属盖（160）在中空金属构件（100）的向外扩张的第一端部（104）的周边处具有周边（166）和第二焊接连接（172）。 帽（160）在扩张的第一端部（104）处封闭中空金属构件（110）的腔室（106）。 当内表面（162）从周边（166）朝向轴线（A）延伸时，盖（160）的内表面（162）是圆锥形的并且随着中空金属构件（100）轴向地远离。 所述盖（160）具有锥形形状的外表面（164），并且所述外表面（164）从所述外围（166）朝向所述轴线（A）延伸，所述外表面（164）沿着所述中空金属构件（100） 。

摘要： A poppet valve (10) has a disk-shaped head (12), an elongated stem (16), and a tapered neck (24) between the head (12) and the stem (16). The neck (24) has an outer surface (32) with an undulating circumferential contour. The undulating circumferential contour improves component strength and heat transfer efficiency, and may also influence valve rotation and inlet charge swirl.
