Claim 0:
1. A suspension system, comprising:
a front left damper including a first compression chamber and a first rebound chamber;
a front right damper including a second compression chamber and a second rebound chamber;
a back left damper including a third compression chamber and a third rebound chamber;
a back right damper including a fourth compression chamber and a fourth rebound chamber;
a first hydraulic circuit including a first cross-over hydraulic line that extends between and fluidly connects said first compression chamber of said front left damper and said fourth rebound chamber of said back right damper;
a second hydraulic circuit including a second cross-over hydraulic line that extends between and fluidly connects said second compression chamber of said front right damper and said third rebound chamber of said back left damper;
a third hydraulic circuit including a third cross-over hydraulic line that extends between and fluidly connects said first rebound chamber of said front left damper and said fourth compression chamber of said back right damper;
a fourth hydraulic circuit including a fourth cross-over hydraulic line that extends between and fluidly connects said second rebound chamber of said front right damper and said third compression chamber of said back left damper;
a first comfort valve positioned to open and close a front left bridge hydraulic line that extends between and is connected to said first cross-over hydraulic line and said third cross-over hydraulic line;
a second comfort valve positioned to open and close a front right bridge hydraulic line that extends between and is connected to said second cross-over hydraulic line and said fourth cross-over hydraulic line;
a third comfort valve positioned to open and close a back left bridge hydraulic line that extends between and is connected to said second cross-over hydraulic line and said fourth cross-over hydraulic line;
a fourth comfort valve positioned to open and close a back right bridge hydraulic line that extends between and is connected to said first cross-over hydraulic line and said third cross-over hydraulic line,
each of said comfort valves being electromechanical valves that control fluid flow between said first and third hydraulic circuits and between said second and fourth hydraulic circuits; and
a manifold assembly with first and second manifold valves that are arranged in fluid communication with a pump assembly and first and second manifold comfort valves that are arranged in fluid communication with said first and second manifold valves by first and second manifold conduits,
wherein said first hydraulic circuit includes a first manifold hydraulic line that extends between and fluidly connects said first cross-over hydraulic line and said first manifold conduit and said second hydraulic circuit includes a second manifold hydraulic line that extends between and fluidly connects said second cross-over hydraulic line and said second manifold conduit,
wherein said suspension system further includes a first fluid passageway that extends between and fluidly connects said first manifold comfort valve and said fourth cross-over hydraulic line and a second fluid passageway that extends between and fluidly connects said second manifold comfort valve and said third cross-over hydraulic line.
