Claim:
A ride control suspension control system for a vehicle comprising: a plurality of sensors providing sensor signals indicative of a plurality of conditions; a suspension control unit mounted between a sprung mass and an unsprung mass, said suspension control unit including a damper having a compression chamber and a rebound chamber, said suspension control unit further including a fluid control circuit selectively providing fluid communication between said compression chamber and said rebound chamber, said fluid control circuit including a single pressure regulator to selectively restrict flow of fluid from said compression chamber to said rebound chamber and from said rebound chamber to said compression chamber; a controller for controlling operation of said pressure regulator as a function of said sensor signals; wherein said pressure regulator includes an inlet and an outlet; said fluid control circuit including a first fluid path interconnecting said inlet and said compression chamber, said first fluid path including a first one-way component preventing fluid flow directly from said inlet to said compression chamber; and wherein said fluid control circuit includes a second fluid path interconnecting said outlet and said rebound chamber, said second fluid path including a second one-way component preventing fluid flow directly from said rebound chamber to said outlet.
