Patent ID: RE38750

Claim:
A fluid valve assembly, said valve assembly comprising: a housing including an entrance to permit fluid flow into said housing and an exit to allow fluid flow out of said housing; a valve disposed in said housing between said entrance and said exit, said valve being configured in an open state to permit fluid flow from said entrance to said exit and in a closed state to block fluid flow from said entrance to said exit; a rotatable driver received by said housing in operative communication with said valve so that rotation of said driver from a first rotational position toward a second rotational position moves said valve from said closed state to said open state and so that rotation of said driver from said second rotational position toward a third rotational position permits said valve to return to said closed state; wherein said second rotational position is between said first rotational position and said third rotational position; and an over-center linkage between said housing and said driver, said linkage configured so that when said driver is between said first rotational position and said second rotational position, said linkage biases said driver toward said first rotational position, and when said driver is between said second rotational position and said third rotational position, said linkage biases said driver towards said third rotational position.
