Mubea Automotive India Pvt Ltd is among the leading producers of valve springs worldwide. Innovative development, high quality and economical, fully inter-linked production systems assure this prominent position. The valve springs are among the most highly stressed components in the car engine. They fulfil requirements, some of which seem to be contradictory. Reduction of spring forces, installation height and moving mass. The spring forces must close the valve reliably and prevent it from lifting off the surface of the cam during movement. Conversely, the spring forces affect the friction level in the engine, and therefore the amount of fuel consumed. For this reason, the spring forces should be kept as low as possible. The optimisation of the dynamic behaviour through reduction of the moving masses, ensures the reliable functioning of the engine at high speeds (rpm). For this reason, Mubea develops both cylindrical springs with symmetrical or asymmetrical coiling and tapered springs or so-called beehive springs. All spring types can be made from wire with round or profiled cross sections. The stress limits for springs of different material types and treatment processes are determined in our own test facilities to ensure that the design criteria are based on a firm foundation. Mubea has developed simulation and measuring techniques to optimise the dynamic behaviour of the valve drive system. In order to validate new designs, prototype springs are manufactured on machinery similar to that used in production and then dynamically tested on engine test benches (towed or fired).

We provide engine valve springs. Racing engines often fail at high rotational speeds because mechanical springs are unable to retract the valves quickly enough to provide clearance for the piston. Renault's pneumatic valve technology replaced steel springs with light weight compressed air bellows. These could retract valves more quickly and reduce the possibility of piston-valve interference, as long as pressure could be maintained. Additionally, the amount of seat tension required to keep a coil sprung valve under control results in greater peak lift loading, with added stress to the entire valvetrain as a result. Pneumatic systems, sharing a common reservoir of pressure retain a more static level of force, controlling the valve effectively, without any attendant peak lift load increase.
