Abstract
An actuator for a vehicle suspension system comprises a first member connectable to one of a sprung mass and an unsprung mass of the vehicle. The first member has an opening with an inside wall of predetermined dimension. A second member is connectable to the other of the sprung mass and the unsprung mass of the vehicle. The second member has an outside wall of a predetermined dimension. The dimension of the outside wall of the second member is adapted so as to be telescopically received within the opening of the first member thereby defining a fluid chamber. A source of pressurized fluid is connectable to the fluid chamber. A fluid seal is located near an end of the first member form a fluid seal between the first member and the second member. Bearings are operatively mounted between the inside wall of the first member and the outside wall of the second member for maintaining the inside wall of the first member spaced form the outside wall of the second member thereby defining a fluid manifold between the inside wall of the first member, the outside wall of the second member, the bearings, and the fluid seal. The bearings permits fluid pressure in the fluid chamber to communicate …
