VALVE‐SPRING MATERIALS AND DESIGN

Abstract

The function of an internal combustion engine valve spring is to provide sufficient force throughout the engine cycle to maintain the tappet in contact with the cam at all speeds within the engine speed range. However, it must not exert such force that will produce unacceptable contact stresses between tappet and cam. The performance requirements of a valve spring are that it must not fail by fracture or, by load relaxation, lose so much of its controlling force that it fails to maintain control between tappet and cam.
