Abstract
A vacuum receiver for a pneumatic conveyor for conveying, e.g., plastic pellets, having a receiving vessel with a material inlet, a material outlet and a conveying gas outlet. A first valve member is provided for opening and closing the conveying gas outlet, and a second valve member is provided for opening and closing the material outlet. Both valve members are connected to a common valve shaft and actuated by a single actuator mounted on a vessel lid. The vacuum receiver of the invention has the advantage of affording positive control and sealing of the material discharge valve while at the same time being economical to manufacture and easily cleaned.
