Abstract:
1. A valve cartridge for a faucet comprising: a valve housing defining a longitudinal axis; a first fluid flow member received within the valve housing, the first fluid flow member including a blind connecting recess and a first sealing surface extending around the connecting recess, the first fluid flow member being configured to rotate about the longitudinal axis; a second fluid flow member received within the valve housing and restrained from moving, the second fluid flow member including an inlet opening, an outlet opening, a sealing bridge positioned intermediate the inlet opening the outlet opening, and a second sealing surface extending around the inlet opening and the outlet opening, the first sealing surface sealingly engaging the second sealing surface; a stem extending along the longitudinal axis and operably coupled to the first fluid flow member for rotating the first fluid flow member about the longitudinal axis to provide selective communication between the inlet opening and the outlet opening through the connecting recess; a cap including a limit stop and supported for rotational adjustment relative to the valve housing independent of the stem; and an engagement member supported for rotation with the stem and configured to selectively engage the limit stop to limit rotation of the stem and the first fluid flow member; wherein rotation of the first fluid flow member above the longitudinal axis changes the position of the connecting recess with respect to the inlet opening and the outlet opening of the second fluid flow control member, thereby adjusting the flow rate of fluid from the inlet opening to the outlet opening; and wherein rotational adjustment of the limit stop relative to the stem and the valve housing to a first position provides a first rotational path to the first fluid flow member, and rotational adjustment of the limit stop relative to the stem and the valve housing to a second position provides a second rotational path to the first fluid flow member, the second position of the limit stop being angularly offset from the first position of the limit stop by 90 degrees.
