ABSTRACT:
The invention provides a shock absorber for wheeled and track type vehicles in which the conventional compression valve is replaced by an acceleration controlled vortex throttle. A beam deflection amplifier introduces fluid radially, tangentially or at an intermediate position into a vortex chamber under control of an accelerometer. The vortex throttle is controlled such that in the presence of acceleration of a wheel relative to the ground shock motion is lightly resisted while long term movement of the wheel toward the vehicle is strongly resisted so that the wheel more closely follows the terrain contour with reduced energy delivered by the wheel to the vehicle body.
