Abstract:
1. A temperature controlling valve comprising a base including a first end wall, a second end wall, and a peripheral wall; among the first end wall, the second end wall, and the peripheral wall being defined a receiving groove, the peripheral wall passing through a first tunnel to flow hot water and a second tunnel to flow cold water at two different axial positions respectively and to communicate with the receiving groove, the peripheral wall including a first passage arranged on one side thereof proximate to the second end wall so as to communicate with the receiving groove; a temperature control set installed in the receiving groove of the base, and between the temperature control set and the receiving groove being defined a first external chamber to receive the hot water and to communicate with the first tunnel, and a second external chamber to receive the cold water and to communicate with the second tunnel; the temperature control set including a first internal chamber to receive the hot water and a second internal chamber to receive the cold water, both of which are in communication with the first passage; the temperature control set further including a casing, and a valve core movably contacting with the casing to be driven to rotate at an original position; a water supplying means used in the casing and the valve core of the temperature control seat, and including a first pore to flow the hot water and to communicate with the first external chamber and the first internal chamber, including a second pore to flow the cold water and to communicate with the second external chamber and the second internal chamber, including a first shield to close the first pore, and including a second shield to close the second pore; a part of the first pore where is not closed by the first shield being defined a cross sectional area to flow the hot water, and a part of the second pore where is not closed by the second shield being defined a cross sectional area to flow the hot water; a cross sectional area of the first pore to flow the cold water and the cross sectional area of the second pore to flow the hot water are relatively increased or decreased with the rotation of the valve core in the casing.
