Abstract
A valve device for a silence opens a bypass passage provided in the silencer to flow exhaust gas through the bypass passage when exhaust gas pressure rises to a certain pressure. The valve device includes a base having a valve opening through which exhaust gas flows, and a plate-like valve for opening and closing the valve opening. The plate-like valve is fixed to the base at its proximal portion, and is bent at both edges thereof in a certain range extending from its distal end toward the proximal portion.
Claims19
A valve device for a silencer, which opens a bypass passage provided in the silencer to flow exhaust gas through the bypass passage when exhaust gas pressure rises to a certain pressure, the valve device comprising:
- a base having a valve opening through which exhaust gas flows;
- and
- a plate-like valve for opening and closing the valve opening, the plate-like valve being fixed to the base at its proximal portion,
- wherein
- the plate-like valve is bent at both side edges thereof in a certain range extending from its distal end toward the proximal portion.
A valve device for a silencer, which opens a bypass passage provided in the silencer to flow exhaust gas through the bypass passage when exhaust gas pressure rises to a certain pressure, the valve device comprising:
- a base having a valve opening through which exhaust gas flows;
- a plate-like valve which opens and closes the valve opening;
- a stopper which restricts a degree of opening of the plate-like valve;
- and
- a plate-like spring which urges the plate-like valve toward a closed position thereof;
- the plate-like valve being fixed to the base and the stopper at a proximal portion of said valve;
- and
- the plate-like valve is reinforced against deflection in a certain range extending from its distal end toward the proximal portion.
