ABSTRACT:
A slide out actuating mechanism for selectively extending and retracting a slidable section of a slide out assembly fixed to a vehicle body includes at least two double acting fluid actuated actuators. Each actuator has a cylinder and an extendible ram. Each cylinder is fixed relative to one of the vehicle body and the slidable section, and each ram is fixed relative to the other of the vehicle body and the slidable section. At least one flow divider having at least two fluid ports directs fluid to and from the cylinders. One of the fluid ports is in fluid communication with one of the cylinders and the other of the fluid ports being in fluid communication with the other of the cylinders, wherein the flow divider maintains the flow of fluid flowing through the ports at substantially equal flow rates to synchronize movement of the rams when moving the rams relative to the cylinders.
