Abstract
A device for conveying powders through pipelines including at least one pumping device which in turn includes a suction inlet and a delivery outlet and a tubular chamber with opposite ends connected respectively to the suction inlet through an input valve and to the delivery outlet through an output valve. A vacuum source and a pressure source are connected upon command to the chamber in axially distanced positions to create a vacuum respectively and alternatively in the chamber in relation to the environment upstream of the device and a pressure in relation to the environment downstream of the device.

Device for conveying powders through pipelines, said device comprising
- at least one pumping device including, in turn, a suction inlets, and a delivery outlet,
- a tubular chamber having opposite ends connected respectively to said suction inlet through an input valve and to said delivery outlet through an output valve,
- an outlet hole of the chamber and an inlet hole of the chamber for connection to only a vacuum source and to only a pressure source, respectively,
- said outlet hole and said inlet hole being located in axially distanced positions along a longitudinal axis of the chamber to create respectively and alternatively a vacuum in the chamber relative to an environment upstream of the device and a pressure in the chamber relative to an environment downstream of the device,
- the outlet hole being located adjacent to the output valve and the inlet hole being located adjacent to the input valve, the outlet hole being located downstream from the inlet hole.
