Abstract
A lubrication system for a turbomachine which includes a reduction gear. The lubrication system includes a main branch and a bypass branch which is arranged in parallel with the main branch. The main branch includes a heat exchanger. The bypass branch includes a hydraulic resistance that is lower than the hydraulic resistance of the main branch. The reduction gear is located downstream of the main branch and the bypass branch. The lubrication system includes at least one bypass device that is configured to supply the bypass branch with lubricant when a pressure value of the lubricant is below a threshold value.
