Abstract
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.
Claims18
A reed valve cooling apparatus for cooling a reed valve fitted in an intake port member formed on a crankcase of an internal-combustion engine, the reed valve having a flange placed between a joining surface of the intake port member and a joining surface of an intake pipe, the reed valve cooling apparatus comprising:
- a water jacket formed in a circumferential wall of the intake port member;
- a highly heat-conductive gasket placed between the joining surface of the intake port member and the flange of the reed valve;
- and
- wherein the flange of the reed valve is heat-conductively connected to the joining surface of the intake port via the heat-conductive gasket in order to transfer heat from the reed valve to the intake port cooled by the water jacket via the heat-conductive gasket.
