Abstract
A water faucet with automatic shut-off for stopping water flow when a hose is removed from the faucet is provided with a housing member that includes an internal chamber, a water inlet port, and a water discharge port having a threaded distal end that is connectable to the end of a water hose. A slide valve is slideably retained within the water discharge port. The slide valve extends from slightly beyond the threaded distal end of the water discharge port into the internal chamber when in a normally closed condition. At least one aperture is formed adjacent the proximal end of the slide valve to allow flow through the slide valve from the internal chamber when the slide valve is moved into an open condition. A seating mechanism is provided adjacent the at least one aperture for preventing water flow from the internal chamber into the slide valve when the slide valve is in the normally closed condition. A bias biasing mechanism is provided to bias the slide valve toward the threaded distal end of the water discharge port.
