Valve Springs are valve train components. The valve train controls the gas or charge exchange in combustion engines based on the reciprocating principle. The camshaft rotates in the valve’s axial motion around the longitudinal axis via an eccentric cam. The valve springs are responsible for ensuring a frictional connection between the valve and cam over the entire engine speed range. High-tensile materials and streamlined production processes save installation space and costs and make it possible to reduce the weight on the cylinder head by up to 10%.

Today’s passenger vehicle engine auxiliaries are usually poly-V belt driven. These are subject to temperature and age-induced changes in length and are prone to engine cycle irregularities and vibrations. Automatic Belt Tensioner Systems are used in today’s accessory drives to compensate for differences in the belt length, to dampen belt vibrations and to ensure reliable transmission of power.

Constant Tension Hose Clamps are self-locking sealing components made of hardened spring band steel. They provide a secure and maintenance-free seal of hose neck connections in coolant and heating circuits as well as in servo systems, fuel delivery systems, air intake systems and charge air systems.
