Faucet valve for sinks, wash basins and other applications

摘要

A faucet valve for kitchen sinks, bathroom washbasins and like applications, said faucet valve being adapted to be made of molded plastics, having relatively few operative parts, and designed to minimize the stresses of assembly and use. The invention has two principal features: the first is the use of a ratchet interlock between the bonnet of the valve and the cover plate of the sink or washbasin, said interlock being oriented to allow the bonnet to be rotated in one direction relative to the valve body in order to thread the bonnet into engagement with the valve body, and to prevent the bonnet from rotating in the opposite direction relative to the valve body when the valve is in use; and the second is the use of a self-centering valve closure member in the form of a spherical ball mounted within a spherical socket with sufficient clearance between them to enable the ball to float relative to the valve seat.
