An appliance for dispensing of bulk material includes a circular-cylindrical stationary cellular housing with individual chambers of a cross-section in the form of a segment of a circle, which are closed in an upper and lower region by respective upper and lower rotating cover plates each having an orifice in the form of a segment of an annulus, the dispensing appliance having in its upper and lower region respective receiving flanges for supporting and guiding the rotating cover plates external of the housing. The upper receiving flange and the lower receiving flange for the respective cover plates are formed by respective flanged plates facing away from the cellular housing and respective flanged plates confronting the cellular housing, between which the respective cover plates are supported and mounted rotatably on bearings provided in each of the respective flanged plates axially opposite one another. The appliance further includes a common eccentric drive for rotating the upper and lower cover plates arranged laterally of the cellular housing.

Appliance for the dispensing of bulk material

A ring seal on moved machine parts, in particular for use on a rotary slide valve, is proposed, which is formed by a pressurized annular channel (11) with a ring seal (12). In a connection flange (10), for this purpose an annular channel (11), parallel to the center axis (19), is formed with a pressure space (15) for pressurization of the ring seal (12).
