Abstract

Opening and closing control device for a turbomachine oil supply channel. Opening and closing control device (1) for an oil supply channel (3) with an outlet (5) connected to a supply nozzle (7) for a centripetal scoop (9) of a turbomachine (11), the centripetal scoop (9) being centered around and rotationally fixed to a rotating shaft (13) of the turbomachine (11), the opening and closing control device (1) comprising a first part (15) rotationally fixed to the rotating shaft (15) and a second part (17) fixed relative to the supply channel (3), the first part (15) being arranged to cooperate with the second part (17) at each rotation in a defined angular location,the opening and closing control device (1) being arranged to alternately interrupt and restore an oil jet (19) from the oil supply channel (3) as a function of a moment of cooperation between the first part (15) and the second part (17).
