초록 ▼

An pneumatically actuated transportation system for use in moving cargo or passengers on a load carrying vehicle or coupled train of vehicles which are disposed along a fluid sealed duct. Load carrying vehicles are motivated within sealed duct sections by a differential air pressure between the front and rear of the vehicular train, the differential air pressure being achieved by propelling or forcing air into the duct section increasing air pressure behind the vehicle while simultaneously evacuating air from the duct section in front of the vehicle. A plurality of air pumping stations are disposed at intervals along the main transport duct, with each station extracting air from a portion of the duct on one side of the pumping device while forcing the air into the portion of the duct on the opposite side of the pumping device. At each station, a system of air pumps and duct valves permit the build-up and reduction of air pressures within adjacent duct sections necessary for propelling the vehicle at a designed speed, with the valve openings being related to the position of the vehicle along the duct itself.

대표청구항 ▼

A pneumatic transportation system comprising: a transport duct which is pneumatically sealed along its length; a vehicle having front and rear sealed portions disposed within said duct, said sealing providing a pneumatic seal between the interior surface of the duct and the vehicle itself; means coupled to said duct for providing air pressure, said means including an intake conduit connected to said duct and an exhaust conduit connected to said duct, said intake conduit withdrawing air from a portion of said duct and said exhaust conduit disposing said air into another portion of said duct; a duct valve connected within said duct disposed between said intake conduit and said exhaust conduit from said air pressure means; a control means for opening and closing said duct valve means as a function of vehicle location within said duct; an intake conduit valve disposed within said intake conduit and an exhaust conduit valve disposed within said exhaust conduit and a by-pass conduit disposed around said air pressure means, said intake conduit valve and said exhaust valve providing for stopping the flow of intake and exhaust air into said duct, said intake conduit valve and said exhaust valve connected to said control means for stopping air flow through said intake conduit valve and exhaust conduit valve as a function of vehicle location.
