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 valve spring retainer is mounted to the upper end of a poppet valve via a pair of cotters in an internal combustion engine of an automobile. The valve spring retainer has an intermediate portion and an outer flange which is engaged with the upper end of a valve spring. The lower surface has a gap between the outer flange and the intermediate portion to decrease wear which is caused by engagement with the valve spring. There is also provided a valve operating mechanism which has a valve spring retainer which has a projection on the lower surface so as to prevent wear.

摘要： A tappet is used in a valve-operating mechanism of an internal combustion engine. The tappet has a top wall and the upper surface of the top wall is engaged with a cam. The lower surface is engaged on a poppet valve which moves up and down. A downward projection which has a recess for storing lubricating oil is formed in the middle of the lower surface of the top wall of the tappet, thereby lubricating interfaces with the cam or valve to improve frictional or wear resistance.

摘要： A poppet valve moves up and down in a valve operating mechanism in an internal combustion engine. A fixed electrode is supported on a cylinder head, and a moving electrode is carried by the poppet valve. The fixed electrode is connected to a circuit, which together comprises a variable condenser and a resistance. The valve moves up and down during firing operation of the engine. Variation in electrostatic capacitance is detected by means of the two electrodes, transmitted to the circuit via a lead and a ground connection, and converted to a voltage by the circuit, thereby enabling detecting valve position more exactly.

摘要： In a passage unit of a recording head, a first ink introduction port of a first reservoir and a second ink introduction port of a second reservoir are formed between the first and second reservoirs. The first and second ink introduction ports are formed at different positions in a nozzle line direction perpendicular to a main scanning direction and are formed to overlap each other in the main scanning direction.

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.
