Plastic integrated anti-scald device

A fluid supply assembly comprising:

• a faucet housing comprising a spout opening, a base adaptor, and an outlet conduit;
• a polymeric manifold housing housed within the faucet housing and mounted to the base adaptor of the faucet housing, the polymeric manifold housing comprising an anti-scald cavity, a mixing cavity, a hot water inlet, a cold water inlet, a mixed water outlet, and an actuator cavity housing a valve, wherein a longitudinal axis of the anti-scald cavity is at an angle from about 5 to about 85 degrees relative to a longitudinal axis of the actuator cavity;
• an anti-scald device housed within the anti-scald cavity of the polymeric manifold housing, the anti-scald device comprising a thermal actuator coupled to a plunger, wherein the thermal actuator and the plunger are held in an open position within the anti-scald cavity with a bias spring,
• wherein, when the valve is actuated, mixed water from the mixing cavity is configured to flow to a sensing region of the anti-scald cavity and to the mixed water outlet, the mixed water being formed by cold water that is configured to flow from the cold water inlet to the mixing cavity and hot water that is configured to flow from the hot water inlet to the mixing cavity,
• wherein, when a temperature of the mixed water reaches or exceeds a pre-set temperature in the sensing region of the anti-scald cavity, the thermal actuator is configured to expand such that the thermal actuator moves the plunger of the anti-scald device along the longitudinal axis of the anti-scald cavity to a closed position to close off the hot water inlet, and
• wherein the longitudinal axis of the anti-scald cavity is at an angle from 10 to 85 degrees relative to a longitudinal axis of the actuator cavity.
