ABSTRACT:
An air lock for discharge of solid particulate material, for example, cut tobacco, from a vacuum line to atmospheric pressure conditions without ingress of air to the vacuum line consists of a radially bladed rotor, an upper inlet, a lower outlet and arcuate side walls, located between and connected to the inlet and outlet, in engagement with the radial extremities of the rotor blades. The side walls are made flexible so that the vacuum in the vacuum line acting through the inlet draws the side walls into sealing engagement with the radial extremities of the rotor blades.
