Ikenoya, Y; Hirano, M; Miura, S

An exhaust gas cleaning device for internal combustion engines, comprising an exhaust system having an exhaust port, a secondary air supply system having an upstream secondary air supply passage communicating with the atmosphere and a downstream secondary air supply passage communicating with the exhaust port for supplying the exhaust system with secondary air, and a reed valve device disposed in the secondary air supply system and adapted to open and close in response to the pulsations of the exhaust gas pressure in the exhaust system. The reed valve device includes a valve housing constituted by a housing structure formed on the cylinder head cover of the engine and a cover member secured to the housing structure, the cover member having a plurality of projections projecting inwardly from the inner surface thereof. The reed valve device also includes a reed valve member clampingly held between the upper surface of the housing structure and the projections of the cover member. The reed valve member divides the space in the valve housing into the upstream chamber connected to the upstream secondary air supply passage and a downstream chamber connected to the downstream secondary air supply passage. The planar area of the reed valve member facing the reed valve member is greater than the area of the reed valve member.
