SUSPENSION DAMPER HAVING INERTIA VALVE AND USER ADJUSTABLE PRESSURE-RELIEF

摘要

A modern suspension damper, for example, a shock absorber or a suspension fork, including an inertia valve and a pressure-relief feature is disclosed. The pressure-relief feature includes a rotatable adjustment knob that allows the pressure-relief threshold to be externally adjusted by the rider “on-the-fly” and without the use of tools.

主权项

1. A suspension damper operable between a compressed position and an extended position, comprising:
a compression chamber having a volume reducing in response to operation of the suspension damper from the extended position to the compressed position; an inertia valve having an inertia mass slideably moveable relative to a first fluid path, the inertia mass at least substantially closing the first fluid path when in a closed position and movable to an open position in response to acceleration of at least a portion of the suspension damper; a blowoff valve at least substantially closing a second fluid path when in a closed position and movable to an open position in response to pressure in the compression chamber equaling or exceeding a first pressure threshold; and a pressure relief valve at least substantially closing a third fluid path when in a closed position and movable to an open position in response to pressure in the compression chamber equaling or exceeding an adjustable second pressure threshold.
