| description | A device for transport of material between chambers at different pressures, comprises a feed chamber, a main chamber having an upper housing with an inlet and a lower housing with an outlet. The feed chamber is coupled to the main chamber at the inlet, and a first slide valve opens and closes the inlet. A second slide valve for opening land closing the outlet may be provided. At least one hollow gasket with an essentially closed wall, preferably an inflatable gasket, is provided between the upper housing and the first slide valve for sealing the inlet; and, at least one gasket with an essentially closed wall, preferably an inflatable gasket, may be provided between the lower housing and the second slide valve for sealing the outlet. Alternatively, a first flap valve for opening and closing the inlet is provided which is pivotally coupled to the upper housing at one side. At least one hollow gasket with an essentially closed wall, preferably an inflatable gasket, is coupled between the upper housing and the first flap valve for sealing the inlet. |
