Abstract
An improved spring damper assembly is disclosed which comprises a helical coil spring having a generally cylindrically shaped sleeve member fitted thereto. The sleeve member has resilient sidewall portions which are designed to frictionally engage surfaces of the coil spring so as to dampen the oscillatory movement of the spring member whereby resonance of the spring is attenuated. The sleeve member includes a continuous integrally formed radially extending flange portion at one end thereof which overlies the end coil of the spring and operates to prevent excessive wear and/or gouging of the seating surface against which the spring is intended to bear due to rotational movement of the spring assembly during cyclic operation thereof.
