摘要： PROBLEM TO BE SOLVED: To provide a gas exchange valve of a combustion engine, particularly a diesel combustion engine including a poppet valve having a valve rod and a valve element.SOLUTION: The valve rod is linearly movably guided in a through-hole of a valve rod guide, and a valve seat surface of the valve element cooperates with a valve seat ring, and thereby, in a closed state, the valve seat surface pushes the valve seat ring, and in an opened state, the valve seat surface is lifted from the valve seat ring. According to the present invention, at least one sliding ring made of a material having temperature resistance, for example, a metallic material or a ceramic material, engages with a notch of the valve rod or a notch of the valve rod guide, for sealing a clearance between the valve rod and the through-hole of the valve rod guide, and a thickness of one or respective sliding rings is set smaller than a width of the notch for engaging with the respective sliding rings, and as a result of it, when the valve rod moves, a lubricant passes through the respective sliding rings by the predetermined pump action.

摘要： A method for manufacturing a valve for which a mold (40) equipped with a die (42) provided with pressing projections (43) that form an umbrella-part face (16) and equipped with a pressing punch (48) is used to perform forging whereby slip deformation is produced from the inner circumferential side toward the outer circumferential side of the umbrella-part face (16), wherein the pressing projections (43) and recessed grooves (46) are provided alternating continuously in the circumferential direction on the die (42), and the umbrella-part face (16) is forged while an intermediate valve product (W3) is rotated at a prescribed angle with respect to the mold (40) in coordination with the pressing operation of the punch (48). The amount of elastic deformation of the source material in the depth direction by means of the pressing projections (43) is greater than with a conventional mold (die), and to that extent a higher hardening of the deep part of the umbrella-part face (16) is enabled. The region of plastic deformation separates in the circumferential direction, but the formed surface (forged surface) of the plastically deformed umbrella-part face (16) is smoothed by shifting the pressing location of the pressing projections (43) in the circumferential direction with each pressing operation of the punch (48).

摘要：鍛造された排気用ポペットバルブの所定領域だけが部分的に固溶化処理されて、フェース部における耐摩耗性と首部・軸部間の高温クリープ強度の双方を満足できる排気用ポペットバルブおよび同バルブの固溶化処理方法を提供。フェース部14を外周に形成した傘部12が徐々に縮径する首部16を介して直線状の軸部18に一体化された排気用ポペットバルブ10で、開弁時に排気ガスが吹き付けるバルブ10の首部・軸部間所定領域Aが高周波発生装置によって固溶化処理されて、この領域Aの結晶粒度を他の領域の結晶粒度よりも粗く(ASTM規格10以下)調整した。バルブ10の首部・軸部間所定領域Aにおける耐熱クリープ強度およびフェース部14における硬度(耐摩耗性)の双方が確保されて、耐久性に優れた排気用ポペットバルブが提供される。
