Suspension system with pitch and roll adjustment

A suspension system for supporting a body relative to at least four points, the at least four points including a front left point, a front right point, a back left point and a back right point, the suspension system including:

• a front left support arrangement between the front left point and the body, a front right support arrangement between the front right point and the body, a back left support arrangement between the back left point and the body and a back right support arrangement between the back right point and the body,
• each respective front left, front right, back left and back right support arrangement including a respective control ram, each control ram including a respective compression chamber and a respective rebound chamber,
• the front left compression chamber and the front right rebound chamber being in fluid communication and forming at least a part of a front left compression control volume,
• the front right compression chamber and the front left rebound chamber being in fluid communication forming at least part of a front right compression control volume,
• the back left compression chamber and the back right rebound chamber being in fluid communication and forming at least a part of a back left compression control volume,
• the back right compression chamber and the back left rebound chamber being in fluid communication forming at least part of a back right compression control volume,
• a control arrangement including a first diagonal fluid transfer device for displacing fluid between the front left compression control volume and the back right compression control volume and a second diagonal fluid transfer device for displacing fluid between the front right compression control volume and the back left compression control volume, each of the first and second diagonal fluid transfer devices having a forward direction and a reverse direction, and
• wherein four possible permutations exist for simultaneously driving the first and second diagonal fluid transfer devices in the forward and backward directions, each permutation corresponding to causing the body to one of:
• roll left,
• roll right,
• pitch to a front of the body, or
• pitch to a back of the body.
