1. Device for mixing mortar cement and like viscous materials in a mixing vessel (1) having a mixing mechanism, and also for feeding the mixed material by means of air pressure produced by a compressor (8) supplied to the mixing vessel (1), which has a motor (7) serving to drive the compressor (8) as well as the mixing mechanism, and a pressure conduit (13) leading to a lower air conduit (14), characterised in that a shut-off valve (19) is arranged in known manner in the intake conduit (18) of the compressor (8) and that an air outlet (5) is provided, which can be coupled to the shut-off valve (19) for exhausting the pressure conduit (13) when the shut-off valve (19) is closed during the mixing phase in the wall region of the mixing vessel (1) adjacent the pressure conduit connection. |
