SYSTEM AND METHOD OF COOLING VALVE WITH MATERIAL IN CAVITY

摘要

A system includes a reciprocating engine, the reciprocating engine includes a poppet valve having a first valve end and a second valve end. The poppet valve includes a valve head having the first valve end. The valve head may open and close a fluid passageway within the reciprocating engine. The poppet valve also includes a stem extending from the valve head and having a first length. The stem has the second valve end and the second valve end is substantially opposite the first valve end. The poppet valve also includes a cavity aligned with a centerline axis of the poppet valve. The cavity includes a first region disposed within the valve head and a second region disposed within the stem, and the second region has a second length that is shorter than the first length. The poppet valve further includes a metal alloy disposed within the cavity. The metal alloy is in a liquid-phase during operation of the reciprocating engine and may transfer heat from the valve head to the stem.
