摘要： A pneumatic conveyor tube booster valve constructed from an annular tapered rubber sleeve in line with the tube and a sealed pressurized housing surrounding the sleeve portion of the tube. Pressurized gas introduced into the housing escapes past the rubber sleeve when the tube pressure drops below the housing pressure by a predetermined amount and enters the tube in substantially the same direction in which material in the tube is moving. Annular lips on the conveyor tubes supports the rubber sleeve against pressures in the tube.
