摘要

The shell (2) has side walls (6) movably fastened at a basebody (4), where the basebody is supported at a supporting arrangement over three accurate supporting points lying in a common plane. The supporting arrangement is formed by a chassis arrangement for moving the shell. The chassis arrangement includes an impeller (14c), where the shell is movable to the impeller. The impeller is connected with the basebody over an individual axis. A chassis axis connects other two impellers each other.
