Patent No. EP3578273 (titled "Mounted Compressor") was filed by MTS Maschinentechnik Schrode on Jun 4, 2019. The application was issued on Aug 11, 2021.
An add-on compactor with a rotating mass mounted on the drive shaft to be pivotable about a transverse axis, the pivot position being adjustable by an adjusting device. The rotating mass is coupled to the shaft in a rotationally fixed manner and can be referred to as a "swash plate" or "wobble shaft". The compactor includes a drive motor coupled to the drive shaft by a freewheel, allowing the unbalance generator to continue rotating without interruption when the compactor is moved.
