Abstract
A shock absorber for providing a linear decelerating force to a machine part by the use of a piston which forces fluid through a series of metering orifices formed by coaction of holes in the piston cylinder and internal annular grooves formed in a metering sleeve which fits over the cylinder. An infinite number of adjustments in the shock absorber characteristics are achieved by moving the grooves in the metering sleeve in orbital pattern relative to the holes in the cylinder. The annular grooves have a semicircular cross section to provide smooth flow through the metering passages and to concentrate the pressure drop in the shock absorber as turbulent flow occurring at the metering point defined by the overlap between the semicircular annular grooves and the associated holes in the cylinder.
