Patent ID: 7040358

Claim:
A nozzle for filling a container with a fluid under pressure, the nozzle including fastening means for fastening on an adaptor connected to the container, a controlled valve for selectively obturating a conduit through which the fluid under pressure may flow, a sensor detecting fastening of the nozzle to the adaptor, said sensor extending adjacent from said fastening means and operatively engaging a kinematic link connected between a control member and said valve, said kinematic link allowing displacement of said valve from a closed position where it obturates said conduit towards an open position where it opens said conduit, said kinematic link including a lever articulated on said valve between a first position where said lever is not displaceable by said control member and a second position where said lever may be displaced by said control member such that, when said valve is in said closed position and said lever is in said first inactive position, said valve cannot be actuated by said control member, said sensor being configured such that upon said sensor detecting fastening of the nozzle to the adaptor, said sensor displaces said lever from said first inactive position towards said second active position of said lever whereby said valve mayb be moved from said closed position to said open position by said control number, wherein said control member is a trigger articulated on the nozzle and provided with a first profiled guide which forms a first part receiving an element secured to said lever without permitting movement of said lever by said trigger, said profiled guide forms a second part which has a geometry different than that of said first part, said element moves along a profile of said first part when said lever is in said second active position thereof whereby said trigger operates said lever to move said valve to said open position.
