In vehicles, different driving characteristics have required the use of shock absorbers having a complexity of adjustable parts. To reduce such a complexity of parts, a shock absorber has its valve and actuator located within the shock absorber's piston and piston rod assembly (40, 38) which is mounted for reciprocation in cylinder (42), the piston (40) dividing the cylinder (42) into upper and lower chambers. A floating inner piston (122) is slidably disposed in a fluid reserve chamber (120) of the piston (40) for movement between first and second positions to selectively open and close fluid passages (142, 144, 146) associated with the assembly to vary the resistance to damping fluid moving through the assembly and between the chambers. The floating piston (122) movement is controlled by a solenoid-plunger and, when the floating piston is in a first position, provides "soft" compression and rebound strokes and, when the floating piston is in a second position, provides "firm" compression and rebound strokes. |
