摘要： PURPOSE:To perform the changeover of plural fluids to plural objects by a single exhaust change-over valve by forming plural inlets and outlets at a valve body, and disposing a rotary valve body, provided with plural passages, inside the valve body. CONSTITUTION:In an exhaust change-over valve 30, a first inlet 34 and a first and a second outlets 36, 37 are formed at a valve body 33, and a rotary valve body 38 rotated around plural rotary valve stems 41, 45 is mounted into the valve body 33. The inlet of a second passage 44 passing the rotary valve stems 41, 45 is communicated with a second inlet 35, and the outlet of the second passage 44 is opened to the side face of the rotary valve body 38. When the outlet of the second passage 44 is communicated only with the second outlet 37, communication between the first inlet 34 and the second outlet 37 is cut off, and the first inlet 34 is communicated with the first outlet 36 by a first passage 43. When the outlet of the second passage 44 is communicated only with the first outlet 36, communication between the first inlet 34 and the first outlet 36 is cut off, and the first inlet 34 is communicated with the second outlet 37 by the first passage 43.

摘要： PURPOSE: To prevent a stain by soot by reducing exhaust gas leaking outside through a clearance between a bearing and a shaft. CONSTITUTION: A washer 9 loosely fitted to a shaft 5 with a clearance not more than 32.5μm in a difference of a diameter, is pressed to the left end of a bearing 4 by an arm 2 under pressure of exhaust gas in a condition of having no clearance. When a temperature rises by exhaust gas, the shaft 5 becomes a higher temperature than the washer 9, and a clearance between the washer 9 and the shaft 5 is eliminated, and both are tightly fixed to each other. In this state, the washer 9 acts as a sealing member to prevent leakage of exhaust gas.

摘要： PURPOSE:To provide an exhaust control valve for eliminating biting of a valve body in an adhered material, and for preventing malfunction or reduction in sealing characteristic at the time of full closing, even when the adhered material is formed on the inner surface of a valve housing. CONSTITUTION:A butterfly-type valve element 2 is arranged in a valve housing 1 so that it can be rotated, and the flow of exhaust is controller by rotation of the valve element 2 by an actuator 8. A blade part 3 is formed on the edge of the valve element 2, and an adhered material adhered or formed on the inner surface of the valve housing 1 is scrapped by the blade part 3 at the time of rotation of the valve element 2. The valve element 2 will not be bitten in the adhered material adhered or formed on the inner surface of the valve housing, and the sealing characteristic at the time of full closing is thus improved.
