Abstract: The invention relates to a fluid nonreturn device (1) comprising a body (2) defining a chamber (5) intended to receive a fluid and having at least one opening (3), the chamber (5) has an internal wall (6) extended by an elastic return member (8) which forms an integral part of said internal wall (6), said elastic return member (8) is extended by a valve shutter (9) forming an integral part of said elastic return member (8), the elastic return member (8) pushes the valve shutter (9) into a position in which it closes off the opening (3) so as to prevent the fluid in the chamber (5) from leaving via the opening (3).

Abstract: A method for manufacturing a strainer, such as a strainer of an ejector used to transfer fuel between two tanks of an aircraft or to supply fuel to an engine is provided. The strainer includes a conduit whereof a first end is intended to be connected to an inlet of the ejector, and whereof a second end is located within a housing including an open face for the passage of fuel, the open face being closed off by a grate acting as a filter. The method includes the step of manufacturing the conduit, the housing and the grate of the strainer as a single monobloc part.
