Abstract (en)

[origin: EP0957238A1] A valve spring (1) is used in a valve operating mechanism for moving a poppet valve (6) up and down in an internal combustion engine of an automobile. The terminal end of the uppermost portion (9) of the valve spring (1) extends in a tangential direction to go away from an axis of the valve spring (1), thereby avoiding contact with a retainer (2) to prevent wear. <IMAGE>
