    摘要： Forming of a valve head portion (1) of a hollow engine valve (V) comprising a material particularly satisfactory in heat resistance is performed by cold forging. On this occasion, the material with excellent heat resistance is worked to form a valve head portion semifinished product (11) having a hollow hole (S11) whose inner diameter (φ11) is equal to the maximum inner diameter (φ11) of a hollow hole (S1) of a finished product of the valve head portion (1), and having a diameter-increased section (111) whose maximum outer diameter (φ12) is equal to the maximum outer diameter (φ12) of a diameter-increased section (1a) of the finished product. Parts of the valve head portion semifinished product other than a central part to a lower part of the diameter-increased section (111) are necked down by cold forging performed a plurality of times to obtain the finished product of the valve head portion (1). This method of obtaining the finished product is provided by the present invention.

    摘要： A system includes an engine head that mounts to an engine block of a reciprocating engine, and the engine head includes an intake flow path, an exhaust flow path, a coolant flow path, and first and second sealing registers disposed on opposite sides of the coolant flow path. In addition, the first and second sealing registers are configured to receive a valve guide that supports a valve stem of an exhaust valve. Moreover, the first sealing register is disposed in a wall separating the exhaust flow path and the coolant flow path. Also, a first wall portion of the wall extends between the first sealing register and an exhaust valve seat configured to receive a valve head of the exhaust valve, and a second wall portion of the wall extends from the first sealing register away from the first wall portion.

    摘要： A hollow poppet valve (10) is provided with an additional flange shape cavity (S1a), in addition to an ordinary valve head cavity (S1) formed in the valve head (14) of the valve (10) in communication with a valve stem cavity (S2) formed in a valve stem (12). A coolant (19) is loaded in the cavities to facilitate dissipation of heat out of the valve. This flange shape cavity (S1a) extends radially outwardly round a bottom portion of the valve head cavity (S1), extending close to a valve seat, thereby significantly facilitating heat transfer between the coolant (19) and the valve seat of the valve, yet, since the flange shape cavity (S1a) does not influences the thickness of other regions of the valve, it does not degrade durability of the valve.
