A sectional diagram of a typical steam boiler feed injector, simplified to show the major parts common to such injectors, showing typical proportions, and using colour and shading to hint at temperature, pressure, and velocity variations in the fluid flows. The SVG was hand coded using a text editor.
The steam injector is a common device used for delivering water to steam boilers, especially in steam locomotives. It is a typical application of the injector principle used to deliver cold water to a boiler against its own pressure, using its own live or exhaust steam, replacing any mechanical pump.

injector valves, which allow steam to force water into the boiler when needed [3]: 42 water gauges , which allow the level of water in the boiler to be monitored [ 3 ] : 91 mechanical stoker controls (when fitted to larger coal-fired locomotives) or oil feed controls for oil-fired locomotives
German example. Note the steam dome, a typically German feature, and also the corrugated furnaces. A "Scotch" marine boiler (or simply Scotch boiler) is a design of steam boiler best known for its use on ships. Sectional diagram of a "wet back" boiler. The general layout is that of a squat horizontal cylinder.
A means had to be provided, of course, to put the initial charge of water into the boiler (before steam power was available to operate the steam-powered feedwater pump). The pump was often a positive displacement pump that had steam valves and cylinders at one end and feedwater cylinders at the other end; no crankshaft was required.
