ABSTRACT:
A bi-directional pneumatic conveyance system which relies upon a single pumping element, and which bi-directionally conveys an item therethrough based upon the position of the item is disclosed. Such a system has plural stations, sensors for sensing pressures at a designated area in each station, a connective tube network pressure generator that includes a pneumatic source and a valve device for internally arranging such generator to create pressure or vacuum conditions within the network, depending upon the state of the pumping element and the internal arrangement of the valve assembly. A control device responds to pressure indications from the pressure sensors and to operator commands in order to control the valve assembly and the pumping element to selectively depressurize and pressurize the tube network and thereby convey the carrier. A terminal station for use in such a pneumatic conveyance system also is disclosed, together with each of a pressure generation apparatus, and a controllable pressurization apparatus that are suitable for use in such a terminal.
