실린더 코크

Cylinders are steam engine components that house pistons that propel the vehicle. Typically, there are two cylinders in the front of the vehicle, one on each side. They are alternately fed steam from the steam chest , with every full rotation of the driving wheels, in the amount set with the cutoff .

Steam in cylinders pushes the pistons inside, mechanically linked to the driving wheels, propelling the vehicle. The used steam is then expelled through a blastpipe, where it mixes with smoke from the firebox in the smokebox, and together they are exhausted to the atmosphere through a chimney.

더 이상 증기가 실린더에 유입되지 않으면 신속하게 냉각됩니다. 이는 보일러와 화실이 분리되어 있기 때문입니다. 그런 다음 실린더의 증기는 매우 빠르게 물로 다시 응축됩니다. 물은 증기와 달리 압축할 수 없기 때문에 실린더에 충분한 양의 물이 모여 피스톤에 의해 밀려나면 실린더가 파손되어 치명적인 파워트레인 고장이 발생할 수 있습니다.

To prevent this, steam engines come equipped with cylinder cocks. They are usually operated by a lever from inside the cab , and allow water to be expelled from the cylinders. However, since steam escapes through the cocks too, they should only remain open for a short time, typically just a few seconds, when the vehicle begins moving from a standstill.

Cylinders can also fill with water if the boiler is overfilled , or from running the vehicle with the cutoff set in the opposite direction.
