Quick-acting female coupling and coupling comprising such quick-acting female coupling

摘要

The end has an isolating plug (2) controlled to be opened by reaction force exerted by a O-ring seal (102) that is placed in an internal housing of the body (101) of a connection male end (B) for being fixed in the female end. The reaction force is obtained by supporting the plug on the seal during the fixing of the male and female ends. The plug has a head (26a) engaged in an end (111a) of a conduit (111) of the body. An independent claim is also included for a service station for filling reservoirs of a motor vehicle with pressurized gas.
