Abstract (en)
[origin: WO2022079382A1] The invention relates to a lubrication system (100) for a turbomachine which comprises a reduction gear (152). The lubrication system (100) comprises a main branch (120) and a bypass branch (140) which is arranged in parallel with the main branch (120). The main branch (120) comprises a heat exchanger (121, 122, 124). The bypass branch (140) comprises a hydraulic resistance that is lower than the hydraulic resistance of the main branch (120). The reduction gear (152) is located downstream of the main branch (120) and the bypass branch (140). The lubrication system (100) comprises at least one bypass device (200) that is configured to supply the bypass branch (140) with lubricant when a pressure value of the lubricant is below a threshold value.
