HIGH EFFICIENCY DAMPER FOR BICYCLE SUSPENSION

摘要

A shock absorber has a valve controlling the flow rate of fluid between a first chamber and a second chamber. The shock absorber may include a blocker that has a variable profile. The blocker may be rotatable using an external adjuster to position the blocker to variably occlude an aperture and vary the damping of the suspension. A bias may also be positioned adjacent the blocker to allow force from the fluid to move the blocker and expose the aperture, thereby allowing fluid to flow through the entirety of the aperture.

主权项

1. A damped bicycle suspension containing a substantially incompressible fluid, comprising:
a valve body defining at least one aperture having a shape and size and allowing passage of the substantially incompressible fluid between a first chamber and a second chamber; a blocker configured to be capable of rotational movement about, and axial movement along, an axis of rotation, wherein each of the axial and rotational movements is substantially independent of one another; a bias positioned against one end of the blocker and axially urging the blocker toward a blocking position; and an adjuster connected to the blocker and configured to rotationally move the blocker;
wherein the blocker is rotationally positionable in a fully open position, where an opening defined in the blocker is maximally adjacent the at least one aperture; andwherein the blocker is rotationally positionable in a fully closed position, where the opening defined in the blocker is maximally away from the at least one aperture.
