Abstract: A hydraulically operated actuator is provided for controlling a roll of a vehicle that includes an actuator connected between a first mass and a second mass of the vehicle. An upper mount assembly is coupled to the first mass and a lower mount assembly is coupled to the second mass. A high-pressure chamber is disposed between the lower mount assembly and the upper mount assembly. The high-pressure chamber has a variable volume of hydraulic fluid disposed therein for selectively restricting the movement between the upper mount assembly and the lower mount assembly. A low-pressure accumulator includes a portal for receiving hydraulic fluid from the high-pressure chamber.

An anti-aeration assembly for minimizing gas bubbles from transitioning between the high pressure chamber and the accumulator, the anti-aeration assembly being disposed with the accumulator.
