Abstract
A concurrent leveling system includes a pressurized air source. A manifold block, having a body defining an air feed inlet, is disposed between air springs and the pressurized air source. The body includes front and rear suspension valves. Each of the suspension valves defines a suspension valve orifice having a first predetermined diameter. The body includes at least one restrictor valve parallel to and in fluid communication with the front suspension valves. The at least one restrictor valve includes a first check valve and a first blocker valve orifice defining a first orifice diameter. The first check valve and the first blocker valve orifice are disposed parallel to one another and in series with the front suspension valves and in fluid communication with the air feed inlet and the front suspension valves for reducing fluid back flow to allow the vehicle to be lowered in nominal loading conditions.
