Abstract
A shock absorber wherein the piston of the piston-piston rod assembly divides the internal space of the cylinder into first and second chambers. The piston has first and second passages for the flow of fluid between the chambers in response to shifting the assembly relative to the cylinder and/or vice versa. One of these passages is controlled by a first check valve which prevents the flow of fluid through the one passage from the first chamber into the second chamber. A second check valve prevents the flow of fluid through the other passage from the second chamber into the first chamber. The piston-piston rod assembly further defines a plurality of bypasses each of which is controlled by a solenoid valve as well as by a pressure-responsive valve.
