Abstract
A nozzle device includes a body, a controller and a core set. The controller is pivotally mounted on the body and is pivotable with respect to the body between a first position and a second position. The core set is slideably received in the body. While the controller is in the first position, the core set is slideable in the chamber and is adapted for coupling with a French type valve. While the controller is in the second position, the core set is fixed and is adapted for coupling with an American type valve.

A nozzle device comprising:
- a body including a guiding member having two opposing ends including a first end and a second end, with the first end of the guiding member having a chamber formed thereon, with the second end of the guiding member adapted for coupling with an air pump and having an aperture formed thereon and in communication with the chamber;
- a controller mounted on the body and pivotable with respect to the guiding member between a first position and a second position;
- and
- a core set slideably received in the chamber and including a needle having a limiting portion delimited by an outer periphery thereof, with the outer periphery of the limiting portion enclosing a non-circle area that delimited the limiting portion, with the limiting portion having a first width being a smallest width thereof and a second width being a largest width thereof, with the chamber delimited by an inner periphery thereof, with the inner periphery of the chamber enclosing a non-circle area that delimited the chamber, with the chamber having a third width being a smallest width thereof, with the chamber having a fourth width being the largest width thereof;
- wherein the relationship between the first, second, third and fourth widths is first width<third width<second width<fourth width;
- wherein while the controller is in the first position, the needle is slideable in the chamber and is adapted for coupling with a French type valve;
- wherein while the controller is in the second position, the needle is abutted against the first end of the guiding member and is adapted for coupling with an American type valve.
