Patent number: 11162609Abstract: A fluid valve for a hydraulic circuit of an aircraft includes a valve body with an inlet and two outlets. The valve further includes a solenoid electric actuator with a ferromagnetic mobile driver and a valve member having a ferromagnetic portion/ The valve member is movable within the valve body along a main direction and has first and second ends that define first and second cavities, respectively, on opposite sides of the valve member. A longitudinal cavity extends through the valve member parallel to the main direction and opens into the second cavity. Relative displacement between the mobile driver and the valve member modifies a communication between the longitudinal cavity and the first cavity via a side opening that is perpendicular to the main direction.Type: GrantFiled: March 27, 2019Date of Patent: November 2, 2021Assignee: SAFRAN AERO BOOSTERS S.A.Inventors: Arnaud Luc Charles Magette, Maxime Vandenbroucke, Cédric Louis Marie Ghislain Frippiat, Jean-Christian Bomal

Patent number: 9885332Abstract: A filter assembly for a fuel injector. In some embodiments, the filter assembly has a longitudinal axis and comprises a filter element, a filter housing, and a cap. The filter element may have a cylindrical section with a first axial end and a second axial end. The tubular filter housing may receive the filter element. The tubular filter housing may include a radial protrusion supporting the first axial end of the cylindrical section when the filter element is received therein. The cap may hold the filter element at the second axial end and encompass the filter housing along an outer circumference. The second axial end may rest directly against the cap.Type: GrantFiled: January 13, 2015Date of Patent: February 6, 2018Assignee: CONTINENTAL AUTOMOTIVE GMBHInventors: Ivano Izzo, Cedric Louis Adrien Leger-Cartier, Luca Matteucci, Marco Mechi, Gianluigi Manzo

Patent number: 9260957Abstract: The present invention relates to the development of tracer fluids, more generally, that of aqueous liquids, intended to be injected under pressure in an oil reservoir, for example from an injection well up to a production well. The object of the invention is to propose a new method of study of a solid medium, i.e. an oil reservoir, by diffusion of a liquid (i.e. injection waters) containing tracers, through said solid medium, which is simple to implement and economical and which remedies the drawbacks of the known tracers for injection waters of oil reservoirs.Type: GrantFiled: December 22, 2010Date of Patent: February 16, 2016Assignee: Total SAInventors: Annie Commarieu, Fabrice Aubertin, Nicolas Crowther, Cédric Louis, Pascal Perriat, Matteo Martini, Olivier Tillement
