Rudolf L'Orange

from Wikipedia, the free encyclopedia

Rudolf L'Orange (born September 18, 1902 in Weißfluss near Danzig ; † January 18, 1958 in Munich ) was a German engineer, inventor and founder of L'Orange GmbH.

Life

Rudolf L'Orange attended high school in Mannheim and then successfully completed an apprenticeship as a locksmith. He then studied shipbuilding at the TH Charlottenburg . Under Felix Graf von Luckner , he was trained as a machine assistant on fishing trawlers. From 1927, L'Orange worked in his father's company, Prosper L'Orange, as a test and patent engineer. During this time he worked on his idea of ​​the diesel direct current injection pump. He also oversaw the series production of injection nozzles for aircraft engines.

In 1932, together with his brother Harro, L'Orange founded the company Gebr. L'Orange Motor Zubehör , Stuttgart-Feuerbach and manufactured punches, cylinders, needles and needle guides for injection pumps for aircraft and ship engines. The company was founded because his father had sold his inventions and the manufacturing rights to them to Robert Bosch AG .

In Hamburg, L'Orange founded the Norddeutsche L'Orange GmbH Hamburg branch in order to be able to supply the marine with its products. With the advent of new drive technologies, L'Orange developed and invented new injection systems, for example the two-volume nozzle for continuous atomization. Thanks to the positive response to his products, he was able to open three more businesses: in Dresden , Niederschöneweide near Berlin and Neudamm in Pomerania. In order to avoid destruction in World War II , the Berlin company was relocated to Glatten in the Black Forest.

In 1947, after the end of the war, a new start was sought for the young company. Together with Karl Maybach , who uses L'Oranges direct current system for its high-speed, light large diesel engines for locomotives and ships, the company became successful again. Around 1950, L'Orange developed the pump-nozzle system together with Maybach, which soon after became indispensable for large diesel engines due to various advantages. This reinvention brought L'Orange so much success that he soon reopened branches in Munich , Hamburg and Stuttgart-Zuffenhausen from Glatten .

After his death in 1958, his widow continued to run the company until 1978.
