Abstract
A control system for a container chassis latching assembly of a trailer provides for initial pressurization of the latching assembly via the trailer supply line. Once a trailer reservoir is sufficiently charged, pressure is maintained for the latch assembly by the trailer reservoir. A preferred control valve interconnects the supply line with a supply port of the valve to provide the desired pressure at a delivery port. A control port of the valve is connected with the trailer reservoir and shuts off this flow once the trailer reservoir has reached a predetermined pressure. Thereafter, the latch assembly is maintained via air supplied from the trailer reservoir.
