ABSTRACT:
A toilet-seat flush-valve operating mechanism comprises two systems, a toilet-seat lifting system and a flush-valve opening system, both employing the fluid pressure as a source of power. A hydraulic cylinder having on the bottom a water inlet is mounted inside a toilet cistern. When a piston-cum-static weight located inside the cylinder moves under water pressure and reaches a position at the upper end of the cylinder, the toilet seat descends and covers the toilet bowl. This piston-cum-static weight, that is, the weight of the static weight, falls down under its own weight to the position at the lower end of the cylinder and, by means of a connecting unit, lifts up the toilet seat. Due to the piston-cum-static weight, which is in balance with and slightly heavier than the toilet seat, relatively low water pressure is sufficient to push the piston-cum-static weight to move upwardly, thus permitting the toilet seat to descend under its own weight. Next, the piston-cum-static weight reverses and descends under its own weight when the actuating fluid is cut off, and through the intermediary of the connecting unit raises the seat and simultaneously, by means of a suspension cord, a secondary static weight and a magnet open the flush valve.
