浮球閥
浮球閥是廁所水箱、水塔等儲水器中用來進水的自動開關。當水箱中的水位低於規定位置時，浮球閥自動打開，讓水進入水箱；當水位達到規定位置時，浮球閥自動關閉，停止進水。[1]浮球閥由墨西哥神父兼科學家何塞·安東尼奧·德·阿爾薩特·伊·拉米雷斯發明，他於1790年在《墨西哥文學雜誌》（Gaceta de Literatura Méxicana）中描述了浮球閥[2]。1797年，埃德蒙·卡特賴特為蒸汽機中的浮球閥申請了專利[3][4]。

"Such flush tank valves as now commonly used are closed against the pressure of water from a source of supply which pressure opposes the movement of the float under rising water level in the tank. This results in a slow or delayed movement of the valve preliminary to its reaching its fully closed position and accordingly develops an objectionable hissing sound due to the discharge of water through the then slightly open valve under full water pressure; this delayed action continuing until the slowed delivery of water to the tank finally raises the water level to a point where the float will be effective in fully closing the valve. This action of the conventional float controlled valves frequently gives rise to a condition where full closing of the valve does not occur with a consequent continuous leakage of water through the valve with a resulting waste of water."
