Lemprex ejector

From TrainSpottingWorld, for Rail fans everywhere

A Lemprex ejector is a type of steam ejector developed by noted Argentinian locomotive engineer Livio Dante Porta. In a steam locomotive, draft is produced in the firebox by exhausting the steam coming from the cylinders out the chimney. The Lemprex exhaust will deliver improved draughting capacity over traditional exhaust systems. However development is only at an early stage. Some work was undertaken in Brazil and is expected to be completed in Argentina by Ing. Shaun McMahon.

The name breaks down: Lem (LeMaitre) Pr (Porta) Ex (Exhaust).
