Abstract
A faucet for controlling the rate of discharge of a fluid under pressure. The faucet has a housing having a passageway therethrough with an inlet port coupled to a fluid supply line. The passageway further has an outlet port open to the ambient atmosphere. A valve seat is formed intermediate the inlet port and the outlet port. A slideway is provided in the housing adjacent to the seat. A flat cantilever spring has one of its ends secured to said housing, the other of its ends overlying said seat, and its intermediate portion disposed within the slideway. A movable element is disposed within the slideway and engages one surface of the spring. The movable element is selectively movable within the slideway along the surface of the spring to regulate the rate of discharge of fluid by varying the distance between the end of the spring and the seat.
