  • Patent number: 6868994
    Abstract: A liquid-dispensing faucet includes a mounting fitting that defines a first flow passage and that is adapted for connection to an associated container with the first flow passage in communication with an internal space of the container. The mounting fitting comprises a valve seat. A body is connected to the mounting fitting. The body defines an inlet, an outlet and a second flow passage that fluidically interconnects the inlet and the outlet. A seal member is connected to the body and is selectively movable between a first operative position and second operative position. The seal member sealingly mates with the valve seat to block the first flow passage when the seal member is in the first operative position. An actuator is operably coupled to the seal member for moving the seal member from the first operative position to the second operative position. In this manner, the valve seat is provided in the mounting fitting rather than as a part of the faucet body.
