A lever (2), whose horizontal axis of rotation (5) is mounted on a float housing (6b), is pivoted with the trigger (9) in one or the other direction of rotation.

Why it's free to use
- Filed August 16, 1991 and granted December 1, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 16, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 16, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
