FIELD: transportation. ^ SUBSTANCE: invention refers to air transportation of loose materials, namely to machines for continuous air transport of loose materials, and can be used at loading and unloading operations in different branches of industry. Machine consists of chamber feeder, lock chamber in a form of bunker and located between them device for material supplying from the zone with one pressure to the zone with the other pressure. The device is performed in a form of horizontally located cylinder with unloading opening with moving piston rigidly connected with the rod with the possibility of horizontal movement. Chamber feeder is equipped with additional opening located symmetrically to the existing opening in relation to vertical axis. The said cylinder is equipped with additional unloading opening located symmetrically in relation to the existing unloading opening of this cylinder. Cylinder unloading openings are located in relation to chamber feeder openings. The cylinder has spring-operated valve at the ends. Between the valves there is the said moving piston. ^ EFFECT: invention provides improvement of production capacity. ^ 2 cl, 1 dwg |
