Single lever mixing faucet

摘要

A single lever mixing faucet is comprised of a body having a through bore in which a spindle is mounted for rotary and axial movement, a pivot member rotatably mounted on the body on which is pivoted an operating handle one end of which engages the upper end of the spindle so that upon pivotal motion of the handle in a vertical plane the spindle is moved between open and closed positions and upon rotary motion of the pivot member the spindle is rotated between hot and cold positions. The pivot member also provides stop means to limit the vertical movement of the spindle in either direction and serves as a retainer for a cover member which encloses at least a portion of the body. The cover member has an access opening and may be rotated to position the opening opposite either of two spring pressed seats in the hot and cold inlet ports. The spindle has an elongated chamber within it and passages in the spindle walls establish communication between the chamber and the inlets. The chamber opens to the exterior at the bottom of the spindle where means are provided to connect a spray attachment to the chamber within the spindle. A one-way valve allows flow of fluid from the chamber to the spray attachment but prevents reverse flow.
