Abstract:
A ball valve for a faucet is pivotably mountable in a valve receiving cavity of a housing body which has a plurality of ports in fluid communication with the cavity. The ball valve has a plurality of openings (90 - 98) in an outer at least partially spherical valve surface, which cooperate with the ports to control liquid flow in both flow rate and temperature mix, and a control stem connected thereto and extendable through a control opening in the body. Further, the ball valve has at least two openings (90, 92) for allowing entry of cold water from a first port of the body and at least two openings (94, 96) for allowing entry of hot water from a second port in the body, one (90, 96) of the openings (90 - 98) having a concave edge section to modulate flow through the opening (90, 96). The opening (90, 96) with the concave edge section has a peripheral shape defined by at least five radial arcs having a respective radial center, at least four of the centers being located within the periphery of the opening (90, 96) and one center being located outside of the periphery of the opening (90, 96) at the side of the concave edge section.
