Claim 17:
18. An air chuck comprising: a body comprising: an output port; an interface port, wherein the body defines a first passageway that extends between the output port and the interface port; and an input port that defines a second passageway that is in fluid communication with the first passageway, the input port being configured for attachment to a pressurized fluid source to facilitate delivery of pressurized fluid through the second passageway and to the first passageway; and a valve core interface slidably coupled with the body and slidable between an extended position and a retracted position, the valve core interface comprising: a shaft rotatably coupled with the body and rotatable in either a tightening direction or a loosening direction, the shaft including a proximal end and a distal end, the distal end being at least partially disposed in the first passageway; an inner core coupled with the proximal end of the shaft; a knob rotatably coupled with the inner core; and a clutch assembly comprising a clutch spring and a ball that cooperate with each other to facilitate selective rotatable coupling between the knob and the inner core as a function of rotational torque imparted to the knob, wherein: when the rotational torque applied to the knob is less than a predefined threshold, the knob and the inner core are rotatably coupled together via the clutch assembly to facilitate rotation of the shaft via the knob; when the rotational torque applied to the knob exceeds the predefined threshold, the clutch assembly allows the knob to rotate relative to the inner core to prevent rotation of the shaft via the knob; the distal end of the shaft comprises a grasping feature that is configured to grasp a valve core of a valve stem; the body defines at least one viewing window disposed along the first passageway for viewing of the shaft from outside of the body; and an internal sleeve that is disposed in the first passageway and surrounds at least a portion of the shaft, the internal sleeve being formed of a substantially transparent material.
