Abstract
A hydraulic damper for adjusting the damping force which incorporates a piston operatively for stroking movement within a cylinder and partitioning the cylinder into separate chambers with first fluid flow control valving interconnecting said chambers for determining said damping force of said unit and fluid bypass passage extending through said neck portion of said piston for controlling the effective passage area of the bypass passage and generating a family of curves for controlling and selecting the damping force of the damper.
