The injectors on 9F 92203 at Railfest York, May 2004

The live steam injector in front is easy to follow. The large 'S' bend to the left is the water inlet, the pipe entering above it is the steam feed, The delivery clack and pipe are at the RH end of the injector and the overflow emerges through the flange holding the whole injector onto the support bracket. The exhaust injector behind is more difficult to fathom out.

The disengaged pipe is the water feed from the tender which fastens onto the fitting immediately above it. This leads to the water valve (controlled above by the fireman) which regulates water to the live steam injector. The similar valve behind takes water from the other side of the tender to the exhaust injector.

A bit better view of the water valves.

The two overflow pipes. The live steam injector overflow has a bayonet fitting on it to facilitate initial filling of the boiler after a washout

The large bore exhaust steam pipe is prominent. The RH small bore pipe carries steam from the valve chest which detects that the regulator is open. This opens up the exhaust steam for economical use.

View looking back shows the huge (5") copper pipe carrying exhaust steam from the front of the loco to the exhaust steam injector

Another view looking rearwards

The steam pipes from the manifold on the firebox top to the two injectors. The valves are controlled by the fireman from inside the cab

The two injectors in all their glory. The live steam injector, in front, delivers water from the back to the front whereas the exhaust injector works from front to back.
