Abstract: PURPOSE: An EGR(Exhaust Gas Recirculation) valve is provided to prevent a diaphragm having low intensity against heat from aging by interrupting heat transfer thereto and to improve durability by inhibiting carbon from flowing back. CONSTITUTION: A diaphragm(11) is moved to a vacuum chamber(13) by compressing a return spring(16) as a strong negative pressure is applied to the vacuum chamber. A valve(4) is separated from a valve seat(3) and interlocking with the lifting of an upper and a lower disk member(12,10). Thereby, a return line is opened and exhaust gas is supplied to an intake system. The hot exhaust gas heats the valve, a working rod(5), a housing(2), and particularly, a ceramic filter(mesh filter,20) by flowing through the housing. Herein, an insulating material(19) is mounted between the ceramic filter and a bush(18) to isolate heat transfer to a diaphragm housing(6) through the bush. If the negative pressure gets smaller, the diaphragm descends by the elastic repulsive force of the return spring. The opening of the valve seat is reduced or closed completely. A washer(15) is useful as a buffer even though vibration is generated from the frequent lifting of the diaphragm. Therefore, the working rod is not separated.
