摘要： To operate a poppet valve in an internal combustion engine, a valve operating mechanism comprises a valve spring retainer which has a taper bore, a pair of cotters which is inserted in the bore to support the poppet valve, and a valve spring between the valve spring retainer and a cylinder head. There is provided means for preventing the cotters from falling out the bore.

摘要： An Al alloy tappet used in an internal combustion engine has a spiral groove on the outer circumferential surface of a tappet body. The spiral groove is formed by pushing a cutting tool against the outer circumferential surface and feeding it in an axial direction. Near the lower end of the tappet body, feed rate is decreased, and the cutting tool is moved away from the tappet body to form a smaller spiral groove which increases in diameter downwards. The outer circumferential surface of the tappet body is covered with a coating layer such as Fe, and the lower end which has the smaller spiral groove is chamfered.

摘要： A tappet is used in an internal combustion engine of vehicles. A core material of the tappet has a helical groove on the outer circumferential surface, and a wear resistant coating layer the ends of which are chamfered. In the vicinity of the end of the core material, the helical groove gradually becomes smaller toward the end, thereby preventing peaks of the helical groove from exposure to the outside.

摘要： After primary blasting is applied to the outer circumferential surface of a cylindrical valve lifter the upper end of which is closed with an abrasive to form a rough surface (7), a secondary blasting is applied to the rough surface (7) with an abrasive which has particle size smaller than that of the first abrasive. Smaller irregularities (8) are formed on the rough surface (7), and a coated layer (6) is formed by thermal spraying on the surface (8), thereby increasing adhesive strength of the coated layer (6) by anchoring effect.

摘要： A valve spring retainer (1) is fixed at the upper end of a poppet valve (7) via a pair of cotters (6) in a valve-operating mechanism of an internal combustion engine. The valve spring retainer (1) comprises a hollow inverted-frustoconical portion (2) and an outward flange at the end thereof. The outward flange comprises an inner portion, an outer portion which is slightly higher than the inner portion, and a guide portion between the inner and outer portions.
