PURPOSE: A waste gate valve of a turbo-charger is provided to control an exhaust pressure applied to a turbine by installing a diaphragm, which is operated by the exhaust pressure, in an exhaust pipe. CONSTITUTION: An inlet of an exhaust pipe(3) formed at an upper portion of a combustion chamber(2) is connected to a turbine(10) of a turbo-charger. In addition, the inlet of the exhaust pipe(3) is also connected to an exhaust device(13) through a waste gate valve(6), so as to control the exhaust pressure of the combustion chamber(2) applied to the turbine(10). The waste gate valve(6) is installed in the exhaust pipe(3) such that a partition wall formed with a plurality of pores is positioned vertical to a length direction of the exhaust pipe(3). A diaphragm supported by a spring is mounted on a center of the partition wall, thereby controlling the exhaust pressure applied to the turbine(10). |
