20140255122 | PNEUMATIC SYSTEM - A pneumatic cargo stabilization system includes a first line configured to be coupled to a dunnage bag and configured to selectively convey a flow of a gas from a source to the dunnage bag, a second line in fluid communication with the gas in the dunnage bag, and a valve coupled in series with the first line, between the source and the dunnage bag. The valve includes a body that defines pressure supply port, a container port, and an exhaust port, a diaphragm assembly, and a spring member positioned to apply a biasing force to a first side of the diaphragm assembly, the second line conveying a feedback to a second side of the diaphragm assembly that opposes the biasing force. | 09-11-2014 |
20140202586 | PNEUMATIC SYSTEM - A pneumatic system includes a first line configured to be coupled to a container, and to convey a flow of gas from a source to the container, a second line in communication with gas in the container, a valve coupled in series with the first line, between the source and the container, and a spring member. The valve includes a body having a first port, a second port, and an exhaust port, and the valve includes a moveable element in communication with the second line and is configured to control the flow of gas through the first line as a function of the pressure of the gas within the container. The spring member is positioned to apply a biasing force to a first side of the moveable element, and the second line provides a feedback to a second side of the moveable element. | 07-24-2014 |
20120315105 | PNEUMATIC SYSTEM FOR USE WITH DUNNAGE BAGS - A pneumatic system for use with dunnage bags includes a manifold configured to communicate pressurized air from a source and a station. The station includes a conduit coupled to the manifold and having an outlet configured to communicate the pressurized air with a dunnage bag. The station further includes a valve coupled to the conduit. The valve is biased closed and configured to open at a pressure corresponding to a predetermined fill pressure of the dunnage bag. | 12-13-2012 |
