steam chest

noun

steam-chest

a chamber that encloses the slide valve of a steam engine and forms a manifold for the steam supply to the valve

First recorded in 1790–1800

The hand wheel and rod to the right are to operate the stop-cock for turning on and off the steam to the steam-chest.

It has a cover called the steam-chest cover, which is securely bolted in place.

The oil mingles with the steam and passes into the steam chest, and thence into the cylinder, lubricating the valve and piston.

Now, setting the engine on one of the dead centres, remove the cover of the steam chest and proceed to set your valve.

If the engine seems to act strangely, and yet the eccentrics are all right, look at the valve in the steam chest.
