INA Valve Tappet
Ensures the right movement
All valve tappets do the same thing. They keep the play between the camshaft and the gas-exchange valves – resulting from wear and thermal expansion – as small as possible, which allows for safe power transmission. With classic hydraulic and mechanical bucket tappets this is realized via cam stroke which strikes the valve directly. This gives rigid drive attributes and achieves very fast valve response.
INA is the world’s largest supplier of valve tappets to the automotive industry. Through a specially-developed 3CF architecture and state-of-the-art coating, INA tappets operate with a minimum of friction. INA’s product portfolio here ranges from mechanical and hydraulic bucket tappets, to mechanical and hydraulic pivot elements, all the way to hydraulic insert elements.
