Abstract
The capability of this shock absorber or damper changing the energy of motion into heat progressively increases as the suspension components progressively wear and become more flexible over their service life. This is accomplished by the use of flow controlling concentric seats of different heights on the rebound valve element. As the outer and higher seat wears down, the working area of the valve element decreases with the inner seat being operative to increase the load to generally compensate for the reduction in friction in the suspension thereby providing a more consistent ride as a function of use.
