Abstract
An assembly for a turbine engine having an oil circuit. The oil circuit includes an air/oil heat exchanger, a primary bypass pipe connecting an intake of the air/oil heat exchanger to an outlet of the air/oil heat exchanger and surrounding the air/oil heat exchanger so as to exchange heat with the air/oil heat exchanger. The oil circuit further includes and a secondary bypass pipe of the primary pipe connecting the upstream end of the primary bypass pipe to the downstream end of the primary bypass pipe. The oil circuit also includes at least one valve for controlling the passage of the flow of oil into the primary and secondary bypass pipes and means for controlling the opening of said at least one valve for a temperature lower than a threshold temperature.
