Female element and coupling intended to form the disconnectable connection of two fluid pipe lines

摘要

A female element of a coupling for the connection of two fluid pipe lines includes a body for receiving a male element and which defines a channel for the passage of fluid and which includes at least one locking element movable in rotation with respect to the body around a generally orthoradial axis (X40 a-X′40 a), between a first angular position wherein the locking element locks the male element in a coupled configuration with the female element, and a second angular position wherein the locking element permits the male element to be separated from the female element and wherein the locking element has a first guide surface in a form of a portion of a cylinder with a circular section centered on an axis of the locking element and the locking element is arranged in a slot in the body of the female element and a second guide surface that rotates with the first guide surface.
