CONNECTION MEMBER WITH STOP VALVE AND CONNECTION INCLUDING SUCH MEMBER

摘要

The invention concerns the female or male member (3) of a connection (1) that can be connected with a corresponding male or female connection member (5) and includes a pusher (33) and a stop valve (35) capable of sliding axially relative to the pusher (33) for coupling to the member (3). The member (3) further includes at least one seal (34) mounted on a first part (35) selected from the pusher and the valve and capable of sealing interaction with a first portion (331) of the second part (33) selected from the pusher and the valve in an uncoupled configuration of the member (3). In the coupled configuration of the member (3), a second portion (333) of the second part (33), defining a seal (34) protection portion (333), is radially provided between the seal (34) and a main fluid flow line (V) in the member (3). The portions (331, 333) have different radial dimensions so that the radial thickness available for the seal (34) in the coupled configuration is higher than the radial configuration available for the seal (34) in the uncoupled configuration. The portions (331, 333) are connected to each other by connection tabs (338) having a constant cross-section.
