Publication number: 20240084939Abstract: Quick-coupling female element. The female element includes a nipple configured for being fitted into a hose and which is rigidly attached to a hollow body extending along a longitudinal axis and which defines a receiving volume. Radial openings provided in the body along a guide axis emerge into the receiving volume and each receive a lock which is guided in translation between a locking position and an unlocking position. The female element includes an operating ring mounted to slide around the body between a locking position and an unlocking position and which comprises guide grooves which cooperate with pins of each lock. The guide grooves associated with each lock are geometrically supported by a guide plane inclined with respect to the longitudinal axis, so that each lock is driven between the locking and unlocking positions thereof when the operating ring is moved between the locking and unlocking positions thereof.Type: ApplicationFiled: August 31, 2023Publication date: March 14, 2024Inventors: Serafim Marques Barroca, Christophe Durieux
