ABSTRACT:
A composite follow valve for internal combustion engines such as an intake and an exhaust valve and the method for producing the same are disclosed. The valve is produced by integrating into the whole a valve head portion molded from a lightweight, heat-resistant material selected from a group of titanium alloys and titanium-aluminium alloys, a stem portion molded from a high-strength alloy steel, made hollow inside to reduce weight, and a stem end portion molded from a hard material selected from a group of martensitic stainless steel, silicon nitride and silicon carbide ceramics. Since the different materials of the separate valve components are selected to meet the requirements of their particular functions and operating condition under which they are placed. Also, because of this separate arrangement, the valve can be produced at a relatively reduced cost, since the use of expensive materials is saved. Furthermore, the valve is molded, not in a whole body, but in separate components, there is no use for expensive isothermal forging machines as in the case of prior art production methods.
