Description from the seller
Original technical drawing – 'Carburateurs Zenith 1912–1914' – Ulysse Valentin, École Professionnelle de Mécanique, Huy (Belgium), circa 1920
Rare and exceptionally detailed technical lesson plate from the early 20th century, fully hand-drawn and partly watercolor-colored, originating from the École Professionnelle de Mécanique – Section Automobile in Huy (Belgium), under the leadership of Ulysse Valentin, professor of auto mechanics and head of service.
The plate shows different cross-sections of carburetors from the French brand Zenith, an influential manufacturer that produced carburetors around 1910–1920 for brands such as Renault, Peugeot, and Hispano-Suiza.
Variants from 1912, 1913, 1914, and 1916 are clearly visible, each with technical improvements in the air-fuel regulation.
The drawing combines multiple schemas and sections.
top left: Zenith 1914 and 1916, with their distinctive needle spray.
Middle: Zenith 1913, with double mixing chamber.
bottom left: Zenith 1912, with early horizontal venturi.
bottom right: an air duct and venturi system with pipe indications for flow direction.
The contrasting hand coloring (black, red, green, yellow) and meticulous shading give the drawing not only an educational but also an artistic value.

Short biography of Ulysse Valentin
Ulysse Valentin (active from the early 20th century) was a professor of automotive engineering in Hoei and Marchin (Liège province, Belgium). He trained young technicians and driver-mechanics during a time when the automobile was still in full development. Valentin was known for his didactic approach, producing large and precise diagrams that helped students understand the workings of engines and vehicles.
His education reflects the transition from horse-drawn carriages to cars. The signatures and stamps on his students' drawings and diplomas make these documents valuable testimonies of the early history of motorsport in Wallonia.
