Self-Adjusting Shock Absorber Having Staged Metering
View pageUS Patent:
42841771, Aug 18, 1981
Filed:
May 14, 1979
Appl. No.:
6/038932
Inventors:
John A. Domek - Wheaton IL
Assignee:
Efdyn Corporation - Geneva IL
International Classification:
F16F 948
US Classification:
188280
Abstract:
In a fluid displacement-type shock absorber, a piston responding to an impacting load moves within a cylinder, forcing hydraulic fluid therein out of one or more orifices into a reservoir. The resistive force of the piston depends upon its velocity, and the area of the orifice or orifices which control the rate at which the fluid can be displaced. The total available orifice are a for discharging fluid from the cylinder is progressively reduced as the piston is displaced from its initial position upon impact. The fixed orifice structure defines successive control regions, each of which is designed to provide a predetermined resistance profile and related deceleration control for a respective load system or mass system. The lightest mass system, traveling at its maximum velocity within the design range, reaches its limiting deceleration rate in the first control region. The heaviest mass system traveling at its lowest velocity within the design range, reaches its limiting deceleration rate in the last control region.
