Disclosed is a shock absorbing suspension system supporting a seat on a flo or of a vehicle The suspension system includes a hydraulic bag filled with a liquid and coupled to support the seat on the floor, the hydraulic bag having an upper orifice. Th e suspension system also includes a reservoir partially filled with liquid, having a lowe r orifice, an upper orifice, and a baffle positioned adjacent the lower orifice to impede the liquid from escaping through the upper orifice. An adjustable valve supports the reservoir on the hydraulic bag and has an internal passageway communicating with the hydraulic bag via its uppe r orifice and the reservoir via its lower orifice to allow the liquid from the hydraulic bag t o pass into the reservoir. The passageway is sufficiently small to dampen motion of the seat toward and away from the floor. The reservoir includes a supply of gas in direct communicati on with the liquid, the gas being compressed when the liquid enters the reservoir through the valve, thereby providing additional shock absorption. The reservoir is positioned above the hydraulic bag, such that gravity keeps the gas above the liquid and out of the valve withou t requiring a diaphragm to maintain gas/liquid separation.
