摘要： A poppet valve moves up and down in a valve operating mechanism in an internal combustion engine. A cylindrical fixed electrode is fixed to a support plate on a cylinder head, and a cylindrical moving electrode is mounted to the lower surface of a valve spring retainer which is mounted to the poppet valve via a cotter. The fixed electrode is connected to a circuit which comprises a variable condenser and a resistance. The valve moves up and down during firing operation of the engine. Thus, variation in electrostatic capacity is detected by the two electrodes, transmitted to a circuit via a lead mounted to the fixed electrode, and converted to a voltage by the circuit, thereby detecting valve position exactly.

摘要： A soldering layer is formed on a valve guide or valve seat and/or a holding bore of a cylinder head in an internal combustion engine. The solder can be melted below the highest temperature which the valve guide or valve seat reaches during operation of the internal combustion engine. The valve guide or valve seat is a press fit in the holding bore of the cylinder head, and with operation of the internal combustion engine, the soldering layer is melted to close gaps on the contacting surfaces between the holding bore and valve guide or valve seat. The soldering layer finally has a higher melting point than the highest temperature of the valve guide or valve seat as above. During operation of the engine, the soldering layer is not melted.
摘要翻译：焊接层形成在内燃机的气门头或阀座和/或气缸盖的保持孔上。在内燃机运行期间，焊料可以熔化到阀导向器或阀座所达到的最高温度以下。阀导向器或阀座是压配合在气缸盖的保持孔中，并且随着内燃机的操作，焊接层被熔化以闭合保持孔和阀导向器或阀座之间的接触表面上的间隙。焊接层最终具有比上述的阀导向器或阀座的最高温度更高的熔点。在发动机运转时，焊接层不熔化。

摘要： A method of manufacturing a tappet which is used in an internal combustion engine of vehicles is provided. 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 small toward the end, thereby preventing peaks of the helical groove from exposure to the outside.

摘要： A poppet valve comprises a valve stem and a valve head which is provided at one end of the valve stem. A plurality of arcuate fins are provided on the surface of the valve head. Two semicylindrical cotters are pushed by a press member, so that the valve is driven and reciprocated. When the valve is moved upward or downward to open a port of a valve casing in which the valve is contained, fluid flows, thereby allowing fluid pressure to act on the fins, so that valve rotates little by little around its axis owing to a slight gap between the cotters and the valve stem.

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, a secondary blasting is applied to the rough surface with an abrasive which has particle size smaller than that of the first abrasive. Smaller irregularities are formed on the rough surface, and a coated layer is formed by thermal spraying on the surface, thereby increasing adhesive strength of the coated layer by anchoring effect.

摘要： In a tappet for use in an internal combustion engine, a tip is fitted in an engage bore between the top wall of the tappet and an engine valve shaft. The tip has a chamfered portion over which a circumferential projection is pressed by a punch so as to fix the tip in the engage bore firmly. A caulking groove is formed by the punch around the engage bore on the top wall. Owing to the chamfered portion of the tip, a cracking is prevented at the bottom of the groove.

摘要： A hollow engine valve includes a shaft portion and an umbrella portion of which diameter is enlarged to form an umbrella shape to be provided on a base end of the shaft portion, a cooling material being enclosed in a hollow portion that is at least formed inside the shaft portion. The shaft portion comprises a first shaft portion in a tip end side, a second shaft portion that is provided in a base end side to have an outer diameter larger than that of the first shaft portion, and a stepped portion formed by a difference in the outer diameters between the first and second shaft portions. A wall thickness of the stepped portion is larger than that of the second shaft portion.
