<P>PROBLEM TO BE SOLVED: To make compact a supercharging device for compressing charge air for an in internal combustion engine having a scroll compressor by simplifying the bearing support of the supercharging device and in particular reducing the dimensions of a front bearing. <P>SOLUTION: A displacement scroll 5 is connected to a supercharger shaft 6 by way of an eccentric arrangement between the front bearing 2 and the rear bearing 3 of the supercharger shaft 6, an externally driven drive element such as belt pulley is provided outside the housing 1 of the supercharging device, and the supercharger shaft is connectable to the externally driven drive element by means of a controllable clutch element. A simpler bearing support and a front bearing of a smaller diameter are achieved by arranging all connections of the drive and/or guide elements for the displacement scroll between the front bearing and the rear bearing. <P>COPYRIGHT: (C)2012,JPO&INPIT |
