420004310 INA VTC hydraulic pivot element

The INA hydraulic pivot element (MPN: 420004310) is a precision-engineered component designed for use in the valve train system of engines. Originating from Romania, this part measures 47.0 x 143.0 x 24.0 mm and is utilized in high-performance applications where low friction and precise control are essential. By incorporating this pivot element, engine builders can enjoy enhanced reliability and longer component lifespan. Dimensions are provided by the supplier and may include packaging dimensions. Valve rods and rockers are critical components of an engine’s valve train, translating rotational motion of the camshaft into linear motion to open and close intake and exhaust valves. Rocker arms pivot on a fulcrum, amplifying camshaft lift and transferring it to the valve stem via the valve rod (or pushrod in OHV engines). These components are located within the cylinder head and engine block, operating in a high-temperature, high-stress environment. Manufacturing typically utilizes hardened steel alloys for durability and resistance to wear. Precise machining and heat treatment are essential for maintaining valve timing and engine performance. Variations include roller rockers to reduce friction and different length pushrods to accommodate aftermarket camshafts.
