Patent number: 11964779Abstract: In order to fill a reservoir while avoiding laborious manual filling operations, there is added to the existing device, including a supply duct, a pump and a measuring probe, a stop valve designed to interrupt the filling as soon as the desired level has been reached, which is detected for example by an air intake which controls the closure of the valve. Two level indicators are added and make it possible to ascertain either that optimum filling has been achieved or that a malfunction is present in the system. Application to the systems for oil filling of aircraft engine reservoirs from another reservoir arranged within the aircraft, generally common to all the engines.Type: GrantFiled: March 13, 2020Date of Patent: April 23, 2024Assignee: SAFRAN AIRCRAFT ENGINESInventors: Mathieu Jean Jacques Santin, Clément Dupays, Bellal Waissi

Patent number: 11512615Abstract: An evaluation of the oil level of an aircraft engine tank from doses of oil delivered from another tank by a pump can be checked by comparing the evaluation of the volume provided by a sensor associated with the engine tank with an estimation of the volume extracted from the aircraft rank, either by another level sensor associated with this tank, or directly from the control of the pump. This comparison is made by a module capable of notifying staff of the need to check or maintain the device, and in particular to check if the sensor is operating correctly. Application to aeronautics, in particular to devices wherein a single aircraft tank supplies all the engine tanks.Type: GrantFiled: December 17, 2018Date of Patent: November 29, 2022Assignee: SAFRAN AIRCRAFT ENGINESInventors: Clement Dupays, Mathieu Jean Jacques Santin, Caroline Marie Frantz, Benoit Gaillot-Drevon
