Connector for a compressed-gas canister and a fastening appliance

Abstract

Connector for a male ejection end-piece ( 16 ) of a compressed-gas canister ( 1 ) intended to supply compressed gas to a fastening appliance that runs on compressed gas and a male inlet end-piece ( 4 ) of a device ( 2 ) for letting compressed gas into the appliance, comprising sealing means ( 3 ) for accommodating the two male end-pieces ( 16, 4 ) and intended to seal the connection between the two end-pieces along cylindrical sealing surface portions ( 34, 35 ). The sealing means ( 3 ) are designed ( 33 ) also to offer sealing surface portions ( 36, 37 ) extending more or less at right angles to the axis ( 8 ) of the cylindrical sealing surface portions ( 34, 35 ).

1 . Connector for, on the one hand, a male ejection end-piece ( 16 ) of a compressed-gas canister ( 1 ) intended to supply compressed gas to a fastening appliance that runs on compressed gas and, on the other hand, a male inlet end-piece ( 4 ) of a device ( 2 ) for letting compressed gas into the appliance, comprising sealing means ( 3 ) designed to accommodate the two male end-pieces ( 16 ,  4 ) and intended to seal the connection between the two end-pieces along cylindrical sealing surface portions ( 34 ,  35 ) extending on each side of the ends ( 23 ,  9 ) of the two male end-pieces ( 16 ,  4 ), characterized in that the sealing means ( 3 ) are designed ( 33 ) also to offer sealing surface portions ( 36 ,  37 ) extending more or less at right angles to the axis ( 8 ) of the cylindrical sealing surface portions ( 34 ,  35 ).  
     
     
         2 . Connector according to  claim 1 , in which there is an annular and transverse seal intended to be housed in two grooves formed in the end surfaces of the two male end-pieces ( 16 ,  4 ).  
     
     
         3 . Connector according to either of claims  1  and  2 , in which the sealing means comprise a double female sleeve ( 31 ,  32 ) for accommodating the two male end-pieces ( 4 ,  16 ), with an annular and transverse sealing partition ( 33 ) in the middle intended to be interposed between the two end-pieces ( 4 ,  16 ).
