Injector Diffusers in stock
Posted: Wed Oct 17, 2018 6:14 am
I have a limited batch of injector diffusers in stock. Scaled from the prototype and cast in bronze.
In the photos below, they are connected to an Eccentric Engineer Standard injector, the diffuser completes the installation per prototype practice. Diffusers were used extensively in the event a boiler check valve stuck open, it dispersed or diffused the jet of hot water and steam outward rather than having the overflow jet aim downward. This prevented rock ballast from being blasted everywhere and risk injury to the engine crew or persons waiting on a passenger platform.
In the prototype photos below, the diffuser center opening is aimed inward toward the center of the tracks per practice on the DM & IR. Other railroads aimed them outward so the fireman could see and regulate the water supply to the injector.
This kit consists of a cast brass investment casting and a threaded brass pipe connector.
