A shock absorber includes a gas compartment within its reservoir compartment. The gas compartment contains gas at a pressure beyond atmospheric pressure. The gas compartment may be defined by an elastomeric bladder which separates the fluid and gas in the shock from one another, and prevents the fluid from becoming aerated during operation of the shock. Because the shock absorber is pressurized beyond atmospheric pressure, the shock absorber provides a "spring assist" to the main suspension spring. The bladder acts as diaphragm and pressure in the bladder is directly transmitted to the fluid. As the main chamber of the shock absorber is replenished with fluid from the reservoir chamber, the gap in the reservoir chamber is taken up by the ever-expanding bladder, and no cavitation occurs in another embodiment, the bladder is replaced by a member mounted for reciprocal sealing movement within the reservoir compartment.
