ABSTRACT:
A spring system for applying a restoring force to a reciprocating member such as an exhaust or intake valve of an internal combustion engine, comprising: a helical spring having open ends and consisting of titanium or an alloy thereof; and a spring seat supporting one of the two ends of the helical spring. Since this helical spring is provided with open ends, mutual striking of the coil wire can be avoided and, thereby, the durability of the helical spring can be ensured in addition to the advantage obtained from the low-mass and high transverse elastic modulus of titanium or its alloy.
