ABSTRACT:
A shock absorber for providing a linear decelerating force to a machine part by means of a piston which forces fluid through a series of orifices formed by co-action of holes in the piston cylinder and holes formed in a sleeve forming a metering tube which fits over the cylinder. An infinite number of adjustments in the shock absorber characteristics is achieved by moving the holes in the metering tubes in orbital pattern relative to the holes in the cylinders.
