  • Patent number: 10816106
    Abstract: An adjustment and temperature limit assembly for a mixing cartridge includes a first piece and a second piece selectively moveable relative to the first piece. The first piece is configured to be attached to a mixing cartridge housing and includes an abutment defining a maximum temperature limit for water exiting the mixing cartridge. The second piece is configured for attachment to a rotating stem extending outwardly of the housing. The second piece is selectively movable relative to the first piece between a plurality of temperature limits that are less than or equal to the maximum temperature limit. A fixing element is configured to be selectively attached to at least one of the first and second pieces to fix an operating temperature at one of the plurality of temperature limits or to set a reduced maximum temperature limit that is less than the maximum temperature limit.

  • Patent number: 10633843
    Abstract: A faucet includes a housing defining hot and cold inlets and an outlet and hot and cold fluid conduits in communication with the hot and cold inlets. A mixer within the housing receives fluids from the fluid conduits and outputs one of the fluids or a mixture thereof. The mixer includes a valve and an actuator configured to move the valve to different positions establishing various ratios of fluids output by the mixer. A temperature actuated flow reducing device within the housing downstream of the mixer restricts a flow of fluid to the outlet when a temperature of the fluid exceeds a predetermined temperature. A first pressure compensating flow regulator upstream of the mixer controls a flow of fluid from the hot fluid conduit to the mixer while a second pressure compensating flow regulator downstream of the mixer controls a flow of fluid through the outlet.

  • Patent number: 10519642
    Abstract: A sensing device for a plumbing fixture includes an electronics housing including a rear wall. The rear wall includes a tool passage therethrough and a fastener head pocket in communication with the tool passage. The device further includes a fastener including head carried in the fastener head pocket of the rear wall of the electronics housing and a body extending away from the head and establishing a fastener axis. The device further includes a sensor assembly including a sensor housing having a first portion coupled to the electronics housing and a second portion carried on the body of the fastener and configured for movement relative to the electronics housing along the body of the fastener.
