A vehicle energy absorbing system for a vehicle having a suspension system, a frame and an axle, wherein the frame is spaced apart from the axle in a vertical direction and the suspension system mechanically couples the frame to the axle. The system includes an expandable air bag mechanically coupled to the frame and to the axle, a distance indicator for indicating a vertical distance between the frame and the axle attached to the vehicle, an air bag pressure control valve fluidly connected to the air bag and coupled to the distance indicator, and a source of air under pressure attached to the vehicle and fluidly coupled to the air bag pressure control valve through a control panel. When the indicator indicates a first distance between the frame and the axle, the valve is positioned in a first position supplying air from the source of air to the air bag at a first air pressure, and when the indicator indicates a second distance between the frame and the axle, the valve is positioned in a second position supplying air from the source of air to the air bag at a second air pressure.

Automatic air bag suspension control system

A multiple filter bag assembly wherein top access is had for removal and replacement of the filter bags through openings in the cell plate subdividing the filter housing into an upper clean gas plenum chamber and a lower baghouse, wherein use is made of tapered filter bags and a cage for easing the passage of the filter bags through the openings in the cell plate during installation and removal.
