Abstract
A device for controlling valve travel of the flush valve of a toilet operated by a rigid linkage rod and for forcibly returning the valve to the closed position. The device may comprise a spring contained within a sleeve. The sleeve has end caps bearing openings for passing the rigid linkage rod entirely through the sleeve and spring. One end cap may be threaded to enable it to compress and immobilize the spring for selectively defeating operation.
