Description: |
| This is the very famous Giffard injector, which had no moving parts and caused quite a furor because its operation seemed to violate the laws of thermodynamics. Giffard had derived its design from first principles. Others had independently discovered the basic idea but their injectors were difficult to get started. Giffard's invention includes a small overflow reservoir which solved the startup problem, and customer tests, including on steam locomotives, quickly demonstrated the superior performance of Giffard's injector. It was licensed to others, including Wm. Sellers in the US. See also US patent 27,979 and British patent GB-186,402,789. |
