A water saving apparatus for water tank includes a stop valve means located above a water outlet, a linkage bar means located above the stop valve means and two chains for connecting the stop valve means with the linkage bar means. The stop valve means has a valve cap engaged with a movable strut and a hollow ball for linking to a tank ball. The linkage bar means has a handle located outside the water tank. The handle engages with a shaft stem and a shaft sleeve for actuating two beams located inside the tank. The chains connect the beams respectively with the tank ball, hollow ball and movable strut. Moving the handle downward, one beam will be moved up to make the hollow ball become buoyant for opening the water outlet rapidly to release a large amount of water to flush feces. Moving the handle upward, another beam will be moved up to make the hollow ball become not buoyant for closing the water outlet sooner so that a small amount of water will be released for flushing urine for saving water.

1. A water saving apparatus for a water tank, comprising in the tank a stop valve means, a linkage bar means located above the stop valve means, and two chains for connecting the stop valve means and linkage bar means, wherein:the stop valve means is located above a water outlet of the tank and includes: a valve cap having a round opening located at the center thereof, an annular flange formed below a bottom side thereof, a pair of arms extended outward from a side thereof for pivotally engaging with a pipe connected with the water outlet, and a pair of valve lugs extended upward from a top surface thereof, a movable strut having two annular recess rings formed at a lower section thereof for engaging respectively with a first and a second valve disk, a transverse trough located at an upper section and a wedge slot formed at a top end thereof above the trough, a position ring fixedly located in the annular flange for limiting movement of the first valve disk between the valve cap and same, a semi-spherical hollow ball pressing against the annular flange for producing a buoyant force desired for the same and having an inlet formed in a side wall thereof for circulating air, and a through hole at a lower portion thereof adjacent the water outlet to facilitate air convection, a gasket located between the valve cap and hollow ball, and a rocker having one end engageable with the transverse trough and another end thereof formed a pinch slot, and a rocker lug extended upward from a middle portion thereof for pivotally engaging with the valve lugs for the rocker to function as a lever; the linkage bar means includes: a handle located outside the water tank having a protrusive strut extended from an inside wall thereof, a spline formed in the protrusive strut, a screw nut and a washer located at one end of the protrusive strut, a shaft sleeve located in the water tank having external screw threads formed at one end thereof for engaging with the screw nut to fixedly mount the same on a side wall of the tank, a first and second notch formed at another end thereof which have different depths, and a first, a second and a third lever located at another end thereof, each lever has a bore formed therein, a shaft stem housed in the shaft sleeve having a spline shaft formed at one end thereof for engaging with the spline, and a first and a second finger located at another end thereof and extended outward, a first beam having a plurality of first slant openings formed at one end thereof, a protrusive first trigger end formed at another end thereof, and a first pivot strut located at a selected position at a middle section thereof and extended outward from two opposite sides thereof for pivotally engaging with the bore of the first and second lever, a second beam having a plurality of second slant openings formed at one end thereof, a protrusive second trigger end formed at another end thereof, and a second pivot strut located at a selected position at a middle section thereof and extended outward from two opposite sides thereof for pivotally engaging with the bore of the second and third lever, and a tank ball having a through aperture; the two chains each being made of a rope strung through a plurality of beads and including a first chain and a second chain, the first chain running through the aperture of the tank ball and having a clip clamped thereon at a selected location, a first upper end engaging with the second slant opening and a first lower end engaging with the wedge slot, the second chain having a second upper end engaging with the first slant opening and a second lower end engaging with the pinch slot.
