Claims29
A valve cartridge for a faucet comprising:
- a valve housing;
- a first fluid flow member received within the valve housing, the first fluid flow member including a first sealing surface configured to rotate about a longitudinal axis;
- a second fluid flow member received within the valve housing and restrained from moving, the second fluid flow member including a second sealing surface, and at least one fluid opening extending into the second sealing surface, the first sealing surface sealingly engaging the second sealing surface to define a common interface including an outer portion having an inner boundary and an outer boundary, the inner boundary defined by the at least one fluid opening;
- a stem extending along the longitudinal axis, the stem being operably coupled to the first fluid flow member and configured to rotate the first fluid flow member about the longitudinal axis;
- and
- at least one cleaning channel formed within at least one of the inner and outer boundaries of the common interface and configured to collect debris from between the first fluid flow member and the second fluid flow member and expel the debris radially from the common interface.
