  • Patent number: 11162609
    Abstract: 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.

  • Patent number: 11009038
    Abstract: The invention relates to a diffuser (5) of a radial or hybrid compressor (2) comprising an internal shroud (20), an external shroud (30) and a series of vanes (10), the trailing edge (12) of each vane (10) being curved in such a way that a distance (di) between the leading edge (11) and the trailing edge (12) of the vane (10) at the mid-height point (h/2) of the vane (10) is 5% to 15% shorter than a distance (d2) between the leading edge (11) and the trailing edge (12) of the vane (10) at the level of the internal shroud (20), the trailing edge (12) also having an evolving cross section comprising a first part forming a low wall (14) in the vicinity of the external shroud (20) and having a height (H) equal to at most 10% of the height (h) of the vane (10), a curved second part and a third part forming a low wall (14) substantially identical to the first part.

  • Patent number: 10563631
    Abstract: The present disclosure relates to filters in general, and the teachings may be applied to a filter assembly for use in a fuel injector, the fuel injector, and internal combustion engines. A filter assembly may include: a filter element with a frame having an axial end and a tubular filter housing receiving the filter element. The filter housing may have a side wall with a taper supporting the axial end. The taper may have the shape of a conic section with an opening angle ? of less than 180°. The outer circumferential surface of the frame may include a first section in the section of the taper having the shape of a conic section with an opening angle ? of less than 180°.

  • Patent number: 9885332
    Abstract: 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.

  • Patent number: 9260957
    Abstract: 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.
