Abstract
A hydropneumatic shock absorber includes an inlet valve and an outlet valve. The inlet valve opens when the piston moves in a contracting direction so that fluid is sucked into a pump chamber, and the outlet valve opens when the piston moves in an extending direction so that the fluid is discharged from the pump chamber into a high-pressure operating chamber. Thus, the pressure in the high-pressure operating chamber does not increase when the wheel bounces, and the oscillation encountered while the vehicle is traveling is properly absorbed so that good riding comfort is realized.
