Method and apparatus for triggered discharge of fluid from a reservoir such as a toilet cistern.

摘要

A method and device for triggered discharge of reservoir; comprising a primary float (7) for producing a primary float force to open an outlet valve of the reservoir. The primary float force is releasably restrained to prevent opening of the outlet valve until triggering of a release and commence discharge of the reservoir is potentially significantly less than the force to required to lever open the outlet valve itself.
