<p>PURPOSE: To simplify and secure sealing by arranging a pair of coupling elements facing against each other through a reciprocally supplementing sealing surface, connecting both of them by interposing a spring and by an engagement means including a coupling nut and by applying a preload by fastening the coupling nut in a fluid coupling of a hydraulic system, etc., of an aircraft. CONSTITUTION: A fluid coupling 18 is constituted of a pair of coupling elements 20, 50, and both of the coupling elements 20, 50 are arranged by making supplemental sealing surfaces 28, 54 face against each other. Additionally, a coupling nut 32 is installed on the coupling element 20, screwed on a screw part formed on the coupling element 50, both of the elements 20, 50 approach each other by fastening of the coupling nut 32 and the sealing surfaces 28, 54 are adhered on each other. Additionally, a spring 46 is interposed between a flange 31 of an inside member 24 of the coupling element 20 and a flange 43 in the peripheral direction of a coupling nut 12, the spring 46 is compressed by fastening of the coupling nut 32, and a preload is applied between the sealing surfaces 28, 54.</p> |
