  • Device for braking containers of pneumatic tube transport installations
    Patent number: 4135685
    Abstract: The present invention relates to pneumatic transport installations and more particularly it relates to a device for braking a container train in a pneumatic transport installation. The tube of the pneumatic transport installation has a plug which seals off the tube, and a hole for the discharge of propelling air. The plug may be constituted either by the end wall of the receiving station, or by a previously braked container. Before the plug the tube is provided with a flow-restricting hole intended to let out the air compressed between the container and the plug, the air braking the container in the braking zone. To ensure the optimum braking conditions, the flow-restricting hole is provided with a controllable bypass valve. The valve is actuated by a special control system.
