Intake valves that control the flow of gas to the combustion chamber made up of a mixture of fuel and air. Exhaust valves that control the flow of high-temperature gas generated within the combustion chamber. Both of these types of valves require strength, wear-resistance, corrosion-resistance and oxidization-resistance in the face of extreme temperatures.

Lightweight and strong titanium compounds are used to satisfy the requirements of high performance, low fuel consumption and silent operations.
These are produced for use in normal cars available on the open market through to racing cars.

By making the frame hollow and injecting it with sodium to act as a coolant, these valves are able to withstand high temperatures. They are used in such vehicles as luxury cars, sports cars and racing cars.

It works to transmit force from the valve spring to the valve through the cotta. Having developed an aluminum retainer for weight reduction, we have also succeeded in developing a light-steel retainer with comparable performance characteristics, which permits further weight reduction, by reducing plate thickness and size.

These components work together with the valve to open and close routes in order to suck in the mixture of fuel and air, and to ventilate the combustion gas exhaust. These must not only be wear-resistant, corrosion-resistant and oxidization-resistant, they must also have low levels of thermal expansion in order to prevent them falling off through expansion and shrinking, and high levels of thermal conductivity to allow the valve’s heat to escape to the cylinder head.

These are attached to the grooves at the ends of the valve frame and join the valve to the retainer. These products are manufactured by cold-forming, which is then followed by surface treatment, quenching and tempering, which enables them to maintain their wear-resistance when in contact with other parts, and because the inside is pliant, it helps them mold themselves to the shape of other parts to make them perfect for joint applications.

The valve rotator is used to rotate the valve in order to prevent blowing or burming of the valve face due to local overheating,to protect the face against partial abrasion due to nonuniform temperature distribution, and to reduce the discharge of hydrocarbons caused by the leakage of unburned gas. FUJI OOZX has the market monopoly for these components in Japan.
