Abstract
The emergency shower includes a discharge outlet pivotable between a first non-use position and a second deployed position about a rotary union, for dispensing water therefrom. A ball valve is positionable between a first flow restricting position and a second flow permitting position, when the discharge outlet pivots between the first non-use and second deployed positions. A linkage system actuates ball valve movement when the discharge outlet pivots, by way of a first link pivotally coupled relative to the discharge outlet and movable therewith and a second link pivotally coupled with the ball valve and responsive to movement of the first link, the second link positions the ball valve in the first flow restricting position when the discharge outlet is in the first non-use position and commensurately moves the ball valve to the second flow permitting position when the discharge outlet pivots to the second deployed position.
