Patent ID: 7114515

Claim:
A valve cartridge for use in sanitary fittings, comprising: a generally cylindrical housing having a proximate extent for support within a housing of a sanitary fitting within which said cartridge is disposed, a distal extent from which water leaves said cartridge and a longitudinal body extending therebetween, said body having a thickness delineated by an outer peripheral surface and an inner peripheral surface, said inner peripheral surface further defining an elongated lumen within said body; said housing further including an annular aperture that connects said outer and inner peripheral surfaces of said body and accommodates placement of a driving member therethrough, said driving member rotating about a longitudinal axis of said housing and correspondingly achieving translational movement through said aperture, said aperture having opposing extents that operate as stops for said driving member and define open and closed positions of said valve cartridge; a rotating disk rotationally disposed relative to a stationary disk wherein said stationary disk has at least one aperture for through flow of cold water, hot water or a combination thereof; and at least one protrusion depending outwardly from a portion of said inner peripheral surface adjacent said proximate extent so as to define at least one each of a corresponding proximate seat and a distal seat therein, said proximate and distal seats supporting an additional valve element in said lumen.
