Abstract
A non-mechanical leak proof coupling for use on a gas carrying pipe having two pipe sections which are moveable relative to each other. The coupling includes a first pipe section having an upstream end in flow communication with a stationary gas source and further includes a second pipe section having a downstream end in flow communication with a vibrating distribution chamber. A downstream end of the first pipe section and an upstream end of the second pipe section are disposed in closely spaced relation to define a gap therebetween. The first pipe section downstream end is in flow communication with the second pipe section upstream end such that the pressurized gas is communicated between the first pipe section to the second pipe section for discharge to the vibrating distribution chamber. The coupling includes structure to cause the gas to be accelerated from a first velocity to a faster second velocity as the gas travels across the gap between the first pipe section and the second pipe section, which thereby creates a negative pressure differential relative to ambient air pressure to prevent the gas from escaping through the gap.
