Abstract
This invention is directed to a discharge controlling device for faucet, characterized in that a control lever is used to push a throttle pin axially positioned within the center of the housing, such that the pin is slidably moved up and down and engages a steel ball which is designed to control the opening and closing of a water discharge aperture. As the control lever is pushed by hand and moved from its lowest closed position to the intermediate, open position where the water can be admitted, the steel ball is pushed away from the aperture by the rod tip of the throttle pin which rises axially. At this instant, water enters through the aperture and flows out of the housing. When the hand is released from the control lever, the throttle pin will fall, and the steel ball, which is subject to water pressure, will immediately return to the position where it closes the aperture. As the control lever is moved manually from its lowest closed position to its fixed open position where it engages the locking slot, the control lever will be secured within the locking slot, and due to the locking effect of the slot, the aperture is kept open to allow continuous water flow even the hand is r…
