Reed valve cooling apparatus for engine

摘要

A reed valve is fitted in an intake port member formed on a crankcase of an engine and the flange of the reed valve is placed between the respective joining surfaces of the intake port member and an intake manifold. A water jacket is formed in a circumferential wall of the intake port member or the intake manifold, or water jackets are formed on both the intake port member and the intake manifold to cool the reed valve by cooling water for a forced cooling. When the water jacket is formed on the intake port member, a gasket of a metal is placed between the joining surface of the intake port member and the flange of the reed valve. The reed valve cooling apparatus can effectively cool the reed valve with cooling water.
