ABSTRACT:
A control valve which includes a main body, a stop valve, a spring-loaded control rod, a support rod and a corresponding shaft, a lid with a fixing element on it, a guide rod and a float cylinder. The float cylinder is restrained only to mover vertically on the guide rod. The stop valve moves vertically in a valve chamber on the upper end of the main body under the influence of water pressure. As water is flushed from the reservoir, the float descends along with the water level and causes the control rod to allow water flow from the upper part of the valve chamber, so that water can flow into the reservoir.
