Discharge and draining device, fitting end and fitting including such a device

摘要

The device i.e. valve device (10), has a chamber (50) defined between walls (31, 37-39) of enclosure (30) when an obturator (60) is in a closed position (C1). The obturator and seal areas (Z92, Z94) define a seal section (S94) located opposite to a front face (22) of the areas. A rear orifice (36) is provided between the chamber and inner volume of female connecting end piece (2). A spring (96) returns the obturator to the position. Another chamber (40) is defined between the walls and isolated from volume and the former chamber, where the section is greater than another seal section (S92). An independent claim is also included for a connector for circulation of pressurized fluid.
