Temperature control device

Temperature control device comprising:

• a body having a first inlet for hot water, a second inlet for cold water and an outlet,
• a chamber to receive the hot water and the cold water,
• a diffuser in the form of a disc having a plurality of openings therethrough to disrupt the flow of hot water after it enters the body via the first inlet, the diffuser being disposed within a fluid flow path extending between the chamber and the first inlet, the entire diffuser being upstream of the second inlet,
• a piston movable in the body between a first position and a second position,
• a single seat in the body against which the piston seats in the first position and from which the piston is spaced in the second position, the cold water able to enter the chamber when the piston is spaced from the seat, wherein movement of the piston controls only the flow of cold water into the chamber but the flow of hot water into the chamber remains constant despite movement of the piston between the first position and the second position, and
• a temperature sensitive device responsive to changes in the ambient temperature,
• wherein, in use, the hot water and the cold water are melded together in the chamber resulting in tempered water which is discharged from the outlet, and wherein when the ambient temperature of the water around the temperature sensitive device increases to a preset temperature level, the piston is at the second position.
