Abstract
A fluid connection element, comprising: a body; a locking ball; a locking ring, movable between a blocking position, blocking the locking ball in a locking position, and a release position, releasing the locking ball; an actuation ball, to drive the locking ring to the release position during coupling; and a maneuvering ring, mounted around the locking ring and comprising an internal radial wall, radially facing the front annular part and whose diameter is less than the diameter of a cylinder coaxial with the body and comprising said actuation ball, the locking ring comprising a radial heel to be driven by the maneuvering ring.
Claims17
A fluid connection element, configured to be coupled with a complementary fluid connection element, the fluid connection element comprising:
- a body, coaxial with a central axis and into which the complementary fluid connection element is fitted during coupling;
- at least one locking ball, movable relative to the body, radially relative to the central axis, between:
- a locking position, wherein said at least one locking ball is capable of locking the complementary fluid connection element fitted into the body, and
- a release position, wherein said at least one locking ball does not oppose a withdrawal of the complementary fluid connection element;
- a locking ring, movable relative to the body along the central axis between:
- a blocking position, wherein said at least one locking ball is blocked in the locking position,
- a release position, wherein said at least one locking ball is free to be moved to the release position;
- at least one actuation ball, received in an elongated housing of the body and configured to be pushed by the complementary fluid connection element along the elongated housing, during coupling with the complementary fluid connection element, so as to axially drive the locking ring from the blocking position to the release position, a diameter of said at least one actuation ball being greater than a diameter of said at least one locking ball, said at least one actuation ball protruding radially outside a front annular part belonging to the body;
- return means, to return the locking ring to the blocking position;
- wherein:
- the connection element comprises a maneuvering ring, movable relative to the body along the central axis, mounted around the locking ring and comprising an internal radial wall, radially facing the front annular part of the body at a front of the elongated housing, wherein a diameter of the internal radial wall is less than a diameter of a geometric reference cylinder coaxial with the central axis and comprising said at least one actuation ball;
- and
- the locking ring comprises a radial heel, to be driven from the blocking position to the release position by the maneuvering ring.
