ABSTRACT:
A torque-override cap is provided for use in a filler neck of a tank. The cap includes a housing configured to engage the filler neck, a shell for providing a hand grip, and a ratchet wheel and a biasing mechanism disposed between the shell and the housing for providing a driving connection between the shell and the housing. The shell includes a plurality of drive teeth, while the ratchet wheel includes a plurality of driven teeth configured to engage the drive teeth to provide a torque-limited connection in the cap-advancing direction and a positive connection in the cap-removal direction. The biasing mechanism operates to yieldably bias the driven teeth of the ratchet wheel into engagement with the drive teeth of the shell to establish the torque-limited and positive connections.
