Patent ID: 7478708

Claim:
A shock absorber comprising: a cylinder having a first end, a second end and a piston chamber extending between said cylinder first end and said cylinder second end, said piston chamber being separated into a liquid filled first piston sub-chamber extending toward said cylinder first end and a liquid filled second piston sub-chamber extending toward said cylinder second end; a first piston received in said first piston sub-chamber, said first piston being axially displaceable through said first piston sub-chamber; a first dampener providing for dampened axial displacement of said first piston through said first piston sub-chamber; a first piston rod extending through said cylinder first end, said first piston being mounted on an end of said first piston rod; a second piston received in said second piston sub-chamber, said second piston being axially displaceable through said second piston sub-chamber; a second dampener providing for dampened axial displacement of said second piston through said second piston sub-chamber; a second piston rod extending through said cylinder second end, said second piston being mounted on an end of said second piston rod; mountings for securing said first and second piston rods to a body and wheel suspension of a vehicle, respectively; and a sealed gas chamber that is isolated from fluid communication with said first and second piston sub-chambers by axially displaceable dividing pistons.
