Изобретение относитс к- энергетическому машиностроению и может быть использовано в двигателестроении.The invention relates to power engineering and can be used in engine building.
Цель изобретени - повьшейие эффективности охлаждени выпускного . клапана путем увеличени охлаждаемой поверхности и защиты внутренней полости от нагарообразовани .The purpose of the invention is to increase the exhaust cooling efficiency. valve by increasing the surface to be cooled and protecting the internal cavity from carbonization.
На чертеже изображен охлаждаемый выпускной клапан теплонапр женнога дизел , общий вид.The drawing shows a cooled exhaust valve teplohapr zhennogo diesel, a general view.
Клапан 1 содержит внутреннюю полость 2 дл подачи охлаждающего воздуха и выпускные отверсти 3 в переходной зоне между головкой и стержнем клапана. На головке клапана установлен тонкостенный кожух 4, образующий в переходной зоне дополнительную проточную полость 5 дл охлаждающего воздуха.The valve 1 contains an internal cavity 2 for supplying cooling air and outlets 3 in the transition zone between the head and the valve stem. A thin-walled casing 4 is installed on the valve head, forming an additional flow cavity 5 for cooling air in the transition zone.
При работе двигател клапан нагреваетс и благодар подводу воздуха от компрессора во внутреннюю полостьWhen the engine is running, the valve is heated due to the air supply from the compressor to the internal cavity.
